junglegroves - work in progress
« on: December 06, 2025, 10:38:07 PM »
lots of updates to share, starting with the updated list of my ficus hybrids...

ficus opposita x carica
ficus fraseri x carica
ficus ulmifolia x carica
ficus racemosa x carica
ficus aspera x carica
ficus lutea x carica

it's sorted from oldest to newest, but also roughly by vigor/viability.  out of around 200 ficus lutea seeds that i sowed, only 1 germinated, but only partially.  an exquisite root emerged from the seed and went into the medium, but after a week of no further growth or development, the seedling quit living.  maybe embryo rescue would work. 

the racemosa x carica seedlings, dang, they are killing me.  i had really low expectations that the racemosa figs would ripen and have seeds, so i was ecstatic when they actually did. then there was the short-lived suspense whether the super tiny seeds would sink in water… numerous did.  this was followed by the painful suspense, which seemed like an eternity, of whether any would actually germinate.  quite a few did, but with considerable variation in vigor and viability.  tragically, so far none of the seedlings has made it past 3".  the inside of the stems become brown and the leaves start to fall off.  initially i sowed the seeds quite thinly, as per my sop, but when i noticed the seedlings dropping like flies, i started sowing them very thickly, which is possible because i actually have quite a few seeds.  well, around 15,000 seeds.  i literally counted 1000 seeds in a single fig.  will at least 1 in 15,000 seeds be an exception to what appears to be the rule of outbreeding depression for this particular batch?  currently i have around 4 distinct types of ficus racemosa.  the trick will be to cross each of them with every carica cultivar, including johannis and palmata.  hah. 

so far the sycidium subgenus (opposita, fraseri, ulmifolia) seems to be a solid tree to bark up for crossing with carica, with the exception of aspera.  back in july i grafted 4 scions (half pencil thick?) of opposita x carica onto a stumped carica in a 45 gallon pot and the scions are now mature.  of course i'm beyond biased, but i think its a beautiful tree.  most people though probably won’t grow it for purely aesthetic reasons.  guessing it will fruit next year and then there will be answers to questions like, will it be pollinated by the carica wasp? 

regarding the question of rkn resistance, this month i will visit my florida grove to see if any opposita x carica seedlings that i planted back in march survived the rkn, and the wild boars.  for anyone who missed my previous threads, earlier this year my partner and i bought 10 acres of old orange grove in central florida, an hour and a half south of orlando.  we live in los angeles and so far have only visited once.  this month will be our second visit and i'm really struggling to keep my expectations as low as possible. 

naturally i know what i want to do with my land.  the biggest question is, what does society want me to do with it?  the most common answer by far is, "develop it!"  the orange groves in the area are being sold off and bulldozed for houses, gas stations, walmarts and so on.  the basic issue is that these private goods are not hamstrung by the problem of free-riding, unlike public goods such as botanic gardens and other green spaces.  if only there was some way to level the playing field! 

back in june i had the opportunity to meet julian duval, the former ceo of the san diego botanic garden, now retired.  turns out he's also a ficus fan!  recently i shared the following plants with him...

aloe tenuior x hercules
annona reticulata red flesh
ficus fraseri x carica
ficus exasperata
ficus ischnopoda
ficus montana red leaf
ficus opposita x carica
ficus septica
ficus tannoensis
ficus ulmifolia
ficus ulmifolia x carica
kalanchoe epiphyte (10 different hybrids)

the aloe and kalanchoes are also my hybrids. 

if duval had still been the ceo of the botanic garden, then the plants i donated would have directly influenced its direction.  i don't think anyone objects to the idea of donating rare plants to a botanic garden.  right?  just like i doubt anyone would object to the idea of donating money to a botanic garden…



out of all the pics i’ve taken at the south coast botanic garden, this one has been by far the most useful.  the donation box says, “help our garden grow!”  but the question is, help their garden grow what?  pansies?  periwinkle?  petunias?  pouterias?  poison oak?

anyone ever watch gone with the wind?  i never have but for some reason this exchange from the movie has stuck with me for decades…

girl: wherever shall i go?  whatever shall i do? 
guy: frankly, my dear, i don’t give a damn. 

ouch, harsh.  but what if you were in his shoes? 

girl: wherever shall i go?  whatever shall i do? 
guy: frankly, my dear, i definitely give a damn!  go to florida and grow luc’s garcinia! 

existential crisis solved! 

what would happen if the botanic garden had 2 donation boxes, one for ornamentals and the other for edibles? 



oooo, wow!  there’s a big clear difference in the demand for ornamentals and edibles.  the people have spoken with their wallets.  let’s be generous and give the people a 3rd option…



well lookit that, it turns out that the greatest demand, by far, is for ornamental edibles. the picture is of chrysophyllum imperiale in my friend’s garden.

invariably there’s always the popular objection that wealthy people will be able to exert too much influence on the rankings.  the irony is profound.  let me try and illuminate it.

the economist israel kirzner shared a simple example of entrepreneurial error… “You opened a hardware store in a place where nobody buys hardware.”  in other words, the entrepreneur guessed that a hardware store was ranked a lot higher than it truly was.  as a result of his bad guess, he barked up the wrong tree and lost his shirt.

hopefully you see how profound the irony is.  the common criticism says that it’s unfair for wealthy people to have so much influence on the rankings, so we’re better off not knowing what the rankings are.  but if everyone actually could clearly see the rankings, then there would never be any need to guess the demand for anything, nobody would bark up the wrong trees, so everybody would be wealthy.   

the proof is in the pudding.  naturally i can’t make the pudding by myself.  what i’ve tried to do is provide the most rudimentary kitchen… junglegroves (jg).  this website for my florida grove is very much a work in progress.  on the homepage will be a list of suggestions ranked by donations.  the donations will be non-binding.  they don’t need to be binding because if the top ranked suggestion is “kwai muk” with a total amount of $224,642 donated for it, even if i don’t pick up this giant gold nugget just sitting at the top of my homepage, i’m sure others will. 

how it works…

1. click the donate button
2. enter any amount
3. in the notes include
a. what its for (ie yangmei)
b. link (optional)
c. your tff username

i’ll manually update the googlesheet when i get a chance.

alternatively, anyone can private message me for my personal paypal to select friends and family and that would cut out the exorbitant fees.  you can also message me on facebook and instagram.

manually having to input the data isn’t optimal but, for all i know, i’m greatly overestimating the demand for donation ranking.  hah.  perhaps at most i’ll only receive one donation a month.  out of the numerous plant forums i’m a member of, i’m giving tff first chance to determine what’s on the jg homepage.  after i return from florida next month, i’ll share jg on my 2nd favorite plant forum, which is… palmtalk (the non-palm category, heh), or agaveville, or orchidboard or… its a long list.  when the members of my 2nd fav forum visit the jg homepage hopefully they will see and learn at a glance what tff’s rare fruit priorities truly are. 

the website files are freely available on github... https://github.com/epiphyte78-web/junglegroves

you can see the developing version here… https://epiphyte78-web.github.io/junglegroves/index.html

the site itself is being freely hosted on netlify… https://www.netlify.com/

it’s too trippy that you can put anything on my homepage, or nearly anything.  no images or videos, for now.  but you can link to any tff thread, any youtube video, any instagram, any facebook group, any blog, any nursery, any page on ebay or etsy.  it doesn’t have to be related to plants but for now that’s what most visitors to jg will be interested in.

what’s the most blasphemous thing i can think of?  “the grove has too many epiphytes”.  this is the epitome of blasphemy, but if someone donates for it, i’ll put it on my homepage.  technically i own my homepage.  practically speaking though, it’s our homepage.  its our mirror that will accurately reflect what’s most important to us as a group.  for this reason, censorship is anathema to me.   as george bernard shaw said, “all great truths begin as blasphemies”.  where would we be today without heretics and infidels?  i literally collect quotes about heresy.  here’s the most recent addition…

Quote
Christ was a wonderful psychologist. He was an infidel of his day, because he rebelled against the prevailing religion and government.  I am a lover of Christ as a man and his works and all things that help humanity, but, nevertheless, just as he was an infidel then, I am an infidel today. I do not believe what has been served me to believe. I am a doubter, a questioner, a skeptic. - Luther Burbank

on this blog entry about burbank i found this fun quote from the los angeles times…

Quote
The San Francisco Chronicle advocates the seizing of Luther Burbank at his home in Santa Rosa and placing him in a chair at Stanford University….The main thing is to get the recluse away from his practical experiments long enough to tell people what he has done.

burbank struggled with financial problems all his life.  he created numerous very useful plant varieties but was never adequately compensated for them.  the plants themselves were a private good, but their creation and existence was a public good.  therefore, burbank was a severe victim of free-riding.  plant patents didn’t exist during his time even though he directly appealed to the us patent office several times.  it was just 4 years after his death, when he was made poster boy of plant patents by his friend thomas edison, that congress enacted them. in burbank’s own words…

Quote
A man can patent a mousetrap or copyright a nasty song, but if he gives to the world a new fruit that will add millions to the value of earth's annual harvests, he will be fortunate if he is rewarded by so much as having his name connected with the result. - Luther Burbank

according to thomas jefferson, “The greatest service which can be rendered any country is to add a useful plant to its culture.” 

what if burbank had a homepage where anyone could post things and rank them with donations?  i’m sure someone would have posted something like, “plant patents are useful!”  how much money would have been donated for this?  burbank wasn’t just friends with edison, he was also friends with henry ford. 

congress wouldn’t have needed to try and guess the demand for plant patents.  just like an entrepreneur wouldn’t have needed to try and guess the demand for a hardware store.

back in july i received this private message here on tff…

Hi,

I'm the Plant Curator at the Edison and Ford Winter Estates in Ft. Myers, FL. I'm looking for F. ulmifolia for our collection. It was grown onsite during Edison's time and I'm trying to acquire it and other "historic" species. I saw on the forum that you planted some ulmifolia seedlings in FL. Can you share with me the source of your seedlings? Or at least pass my information along to them? We are members of the BGCI plant exchange but there are only four gardens that list the species and they are all overseas.

Thank you,
Britta Soderqvist

what’s the demand for a plant that isn’t for sale?  what's the demand for a plant that doesn't even exist?  we shouldn’t have to guess.  in theory it should be easy enough to find out simply by checking jg. 

honestly it was the first i’d even heard of the edison and ford winter estates.  of course i quickly ran over to wikipedia to look it up…

Quote
From 1914 to 1918 (World War I), Edison became concerned with America's reliance on foreign supplies of rubber. He partnered with Harvey Firestone and Henry Ford to try to find a rubber tree or plant that could grow quickly in the United States and provide a domestic supply of rubber. In 1927, the three men contributed $25,000 each and created the Edison Botanic Research Corporation in an attempt to find a solution to this problem. In 1928, the Edison Botanic Research Corporation laboratory was constructed. It was in Fort Myers that Edison would do the majority of his research and planting of his exotic plants and trees.

edison grew ficus ulmifolia to test its sap quality?  if burbank had been there, and the 2 guys had put their heads together, then maybe they would have crossed ulmifolia and carica.  should burbank have been there? 

burbank: wherever shall i go, whatever shall i do? 
edison and ford: frankly, my dude, we definitely give a damn!  come to florida and cross ficus!   

existential crisis solved!

the tug-of-war is always real.  it’s a basic fact of economics that no single resource can be in two places at once.  this is what it means for society’s resources to be limited.  burbank couldn’t simultaneously be in california and florida.  where was he most needed?  all he could do is guess.  but again, having to try and guess demand is detrimental, primitive and the cause of poverty. 

currently only one donation has been made on jg, $1.53 for bulbs by my partner.  she does all the finance stuff and is currently planning to do some credit card wizardry to pay for a fence for jg.  seems like most quotes are around $40,000.  yikes.  admittedly her plan doesn’t sound very copacetic to me.  then again, she’s even more skeptical of my donation ranking plan, heh.  oh ye of little faith!   

when i visited wikipedia just now i was bashed on the head by their giant donation appeal.  each year it keeps getting bigger.  if wikipedia had donation ranking on their homepage, what would be at the top of it?  is jimmy wales too scared to learn the priorities of his donors?  just now when i visited inaturalist i was also bashed on the head by their giant donation appeal.  three days ago i posted a relevant journal entry there… grievance #67 of 95.

in comparison to donation appeals, traditional advertising is way worse, it constantly bashes us on the head.  youtube ads are incredibly annoying.  not only are they disruptive, but they are also entirely irrelevant.  its a huge waste of my time and the advertiser’s money.  which is worse though… advertisements or paywalls? 

75 years ago ira condit was the very first person in history to ever manually cross 2 ficus species.  his landmark paper… an interspecific hybrid in ficus… is behind a paywall.    by the time of his death in 1981, his paper had been cited 5 times.  by 2000 it had been cited 7 times.  citations/votes (cheap signals) should never be used to rank anything.  using money (costly signals) as a barrier to accessing his paper is a terrible idea.  instead, money should be used to elevate the paper on the publisher’s homepage.  money should be used to buy more eyeballs for condit’s paper.  money should be used to create a big bright flashing neon sign with an arrow pointing directly to condit’s shoulders.  the message should be painfully loud and clear… “stand on condit’s shoulders!” 

google took the idea of citation ranking and applied it to page ranking.  each link to a page is a vote for it.  is it a coincidence that, according to franklin foer, the top google search results for “god” are “aggressively, offensively vapid”?  this is what he wrote in the death of the public square, an article in the atlantic, which is behind a paywall.

on youtube, baby shark is ranked infinitely higher than all the videos about ira condit and luther burbank combined.  it highly behooves us to explore the alternatives.  i know its cliche for each generation to worry about the next generation, but in this case the actual term for some of the most popular content is “brainrot”.  there’s never been a time in history when kids had so much control over society’s limited attention as they do now.  we were all kids once, we should all remember how bad our priorities were.  from pooping our pants, to not wanting to eat our veggies, to not wanting to learn our times tables, to thinking that our favorite book or band in the 5th grade would be our favorite for life, its a long list.  kids having bad priorities is not new.  what is new is that, for the first time in history, views/votes have put kids in the driver’s seat.  for the first time, thanks to the internet ranking virtually everything with cheap signals, a huge portion of society’s limited attention has been hijacked by the lord of the flies. 

is jg the antidote to brainrot?  well, its a basic fact that while kids have more time than adults, adults have more money than kids.  with the current system the playing field is unlevel…its advantageous to kids and disadvantageous to adults.  with jg it would be the complete opposite.  we should tell kids, “eat ur veggies and look at jg!”  jg would tell kids to stand on mr. burbanks shoulders. youtube would tell kids to stand on mr. beasts shoulders. 

what if jg actually tells kids to stand on mr. prada’s shoulders?  the first step in improving society’s priorities is by far the most important step: knowing what they actually areknowing is half the battle.  right now we don’t know if tff will elevate whichever fruit is the closest equivalent to prada.  it’s funny because… all the fruits at the top of our wish lists are the equivalent of prada.  we’re not here because we’re excited and passionate about common fruit, we’re here for the rarest of the most rare, which is way out of reach, on the other side of the world.  or they are in my backyard.  all my fig hybrids are rarer than any prada product.  sure, i could try and guess which seeds, seedlings, or scions to put on figbid, but the tug-of-war is real. 

one of my fav examples is florida fruit geek.  for quite a while he was doing some really great work testing rkn resistance of various rootstocks for ficus carica.  but then out of nowhere, mulberries won the tug-of-war.  another fav example is flying fox fruit on instagram.  in some of his posts the fruit trees win, but in other posts the skateboarding wins.  and i imagine all of his young skater friends on one side of the rope, and on the other side are all of us old fogies.  its a pretty close fight with clicking the heart button.  too close.  so we should definitely switch to donations.  the 3rd example, the most painful example, is florida natural farming.  we lost the tug of war to miniature zebu cows.  it wasn’t a fair fight, they are way more charming than all of us combined.  the only chance we had was with donations. 

in my case, what’s charming my socks off are my epiphytic kalanchoe hybrids.  unlike with the figs, i don’t even need to pollinate them, because they are naturally pollinated by the most charming bird ever, hummingbirds.  the seeds quickly germinate and the seedlings are instantly fascinating and captivating because they are so incredibly diverse.  and they flower within a year.  and they grow on trees!  all trees always need more epiphytes, contrary to any blasphemous rumors.   

so yeah.  the tug-of-war is real.  its no joke.  and thanks to the free-rider problem, we are constantly sabotaging our side of the rope.  this would be far less rampant with literal tug of war.  if we were all in person engaging in tug-of-war we’d all have the good sense to at least pretend we were pulling hard on the rope.  but we aren’t in person, there is no literal rope, and chipping in hasn’t been a team effort, until now. 

in theory jg provides us, the members of the tropical fruit forum, with the single most powerful weapon to combat brain drain.  obviously its not a secret weapon.  its not intended to be.  because the fact is, perhaps some of our biggest brains should be solving bigger problems than a shortage of rare fruit.  well, the biggest obstacle to the abundance of rare anything is the bad distribution of brains.  too many brains barking up the wrong trees!  this can be solved, by fixing how we engage in tug-of-war.  when its with clicks, we lose to kids and people who barely care.  and when we stand on the sidelines, we obviously lose.  the only way to win, for everyone to win, is when the incentive to free-ride is minimized. 

the grove next to jg is on the market.  whoever buys it will most likely develop it, based of course on their guess about demand.  ideally they wouldn’t have to guess.  they would just look at the jg homepage, where they would see the demand for a gas station relative to the demand for a wildlife sanctuary.  conservation and development would be, for the 1st first time in history, on a completely level playing field, since they would be equally weighed down by the incentive to free-ride.  hopefully the incentive is as small as possible, but whatever it is, it will equally apply to conservation and development.  people on team gas station wouldn’t be buying gas, they would be donating to credibly quantify their perception of its scarcity, just like the people on team wildlife sanctuary wouldn’t be buying wildlife, they would be donating to credibly quantify their perception of its scarcity.  its not buying gas vs donating for wildlife.  its donating for gas vs donating for wildlife. 

of course the new owner could still do whatever he wanted with the land, but at least he wouldn’t be ignorant of society’s true priorities.  if he learns that the demand for a garden center is way higher than the demand for a gas station, you’d figure he’d make the socially optimal decision. 

we all intuitively understand the idea of a kid being so happy in a candy store.  for us the closest equivalent is bellamy trees.  we happily scroll and scroll carefully considering each and every one of the numerous varieties of tantalizing options.  with this example in mind, we should all grasp the problem with inflation.  if inflation is 50%, we only get half the bang for our buck.  this makes our dollar half as useful.  however, the same thing would happen if the amount of options were reduced by half.  our happiness in this “candy store” would be reduced by half.  we’d only get half the bang for our buck. 

the point of money is to directly influence the rankings (society’s priorities).  the more things to rank, the more useful our dollar is.  the less things to rank, the less useful our dollar is. 

with the current system, there are way too many places and spaces where our money doesn’t have the opportunity to do what its meant for.  on netflix we don’t have the option to use our money to improve the ranking of garden content.  same on youtube.  same with google search.  same at a library.  same at a school.  in all these cases, and countless more, our money might as well be a chucky cheese token.  its useless.  we’re all getting far less bang for our buck than we should be getting. 

if anyone has any questions, comments, concerns, critiques or suggestions please reply with them.  freely chiming in should always be an option.  however, the more people who do so, the greater the chances that something valuable will be buried.  this is why its so important to have the option to chip in with your money to elevate anything you really don't want other people to overlook. 

i doubt anyone thinks this post is too short, but hopefully someone in the future will be interested in reading my previous version, a 33 page work in progress… rare fruit economics.

lastly here’s a pic i took today of one of the best looking seedlings of ficus racemosa x carica...



the pic really doesn’t do it justice.  it looks incredible, a really wonderful mix of traits from both parents.  i know that i shouldn’t get attached because i’m sure it will croak any day and break my heart like all the other seemingly vigorous seedlings of this cross.

Epiphyte,

Since you have plenty of seeds to work with, you might consider micro grafting your racemosa cross when they get a couple inches tall. I seem to recall that many wide hybrids have weak root systems. I would try a high humidity/low light system with the leaves on (similar to the process for vegetable grafting) or an approach graft. Maybe some future generation will look back on you as the Luther Burbank of Figs.  ;D

Galatians522, you read my mind.  when the 1st couple seedlings of racemosa x carica... uhhhh... race x car... racecar?  when the first two racecars to reach a couple inches stalled out, and started dropping their leaves, i grafted them onto rooted racemosas in zip lock bags indoors.  the scions sat there for a couple months and then slowly faded away.  maybe by the time i grafted the scions it was already too late.  or maybe they weren't compatible with racemosa. 

fortunately, since i started sowing the racecar seeds rather densely, i have around a dozen seedlings that look promising.  all are still in bags except the one in the pic above which i put in a tall tree pot indoors.  it didn't do much while i was gone but it has since made a new leaf.  i probably shouldn't get my hopes up since who knows if any of the racecars are truly out of the woods?  sword of damocles of wide crosses. 

regarding burbank, a month ago in the growingfruit forum i saw this thread about burbank, which shared this paper.  he made an incredible variety of crosses.  is this how we define him?  or do we define him by his most useful crosses? 

what if burbank's most impactful contribution wasn't any of his hybrids, but was his advocacy for plant patents? 

what would it be like to be defined by what you overlooked? 

Quote
No, Isaac, don't put the magnifying glass down! Something even more amazing is hidden in the light...  a code, a key to the cosmos.  Isaac Newton didn't miss much, but that one was a beaut.  He just walked right past the door to a hidden universe; a door that would not swing open again for another 150 years.  It would fall on another scientist, working in the year 1800, to stumble on a piece of evidence for the unseen worlds that surround us. - Neil deGrasse Tyson, Cosmos

from google search ai...

Quote
The scientist Neil deGrasse Tyson refers to is William Herschel, who discovered infrared radiation in 1800.  In the episode of Cosmos: A Spacetime Odyssey, Tyson explains that while Isaac Newton correctly identified that white light is composed of a spectrum of colors, he did not investigate the "unseen" parts of that light.

About 130 years after Newton's work, Herschel conducted an experiment using a prism to split sunlight into a rainbow. He placed thermometers in each color to measure their temperatures and noticed a surprising result: a thermometer placed just beyond the red end of the visible spectrum recorded a higher temperature than any of the visible colors. This evidence proved the existence of "invisible light," the first step in uncovering the full electromagnetic spectrum.

what a cool experiment.  not nearly as cool though as the junglegroves experiment to reveal hidden demand.  8)

I would argue that Burbank's most important contribution depends on what person you are talking to. If it is a plum farmer, they would probably say the Santa Rosa Plum. A potato farmer would say that it was his work with potatoes.

I think a more useful metric in defining his accomplishments is found in identifying what caused him to be successful. I think it boils down to two things. 1. Incurable curiosity and 2. Dogged determination. One of the most defining moments in Burbank's life was the day that he decided to grow potato seeds in spite of being told that nothing good would ever come of it. He grew the seeds because he wanted to see what would happen, not because of any particular expectation on his part or because popular opinion told him to do so. He was curious. Because he wanted to know, to see for himself, something amazing happened. In addition to the curiosity, he had the determination to see something through. It took thousands of crosses to achieve his rubus hybrid for example.

I would also differ slightly from Neil deGrasse Tyson's take on Newton. Newton did not fail because he didn't discover everything there was to learn. If that is the standard, everyone who ever lived was a failure. I would say that Newton built a foundation that others might stand upon. To this day we do not understand light fully. Just Google quantum entanglement--we've been looking at it for thousands of years and still don't really know what it is. One thing we do know is that we have only scratched the surface of what there is to learn.

coincidentally, yesterday i grafted scions of santa rosa plum onto a couple neighbor's trees.  one neighbor has a big japenese plum tree in their front yard that only bears a few fruits.  the other neighbor has a seedling apricot in their front yard that seems old enough to have fruited, but hasn't.  the seed came from a grafted apricot tree in the backyard.  i grafted santa rosa onto both the apricot trees. 

just asked google search ai about burbank's plum...

Quote
Luther Burbank developed the Santa Rosa plum through a massive, non-scientific process of interspecific hybridization and mass selection. He famously prioritized results over meticulous data, once screening roughly 7.5 million plum seedlings to find his best varieties.
The Development Process
1. Global Importation: Burbank’s breakthrough began in 1885 when he imported 12 healthy plum seedlings from Japan. He saw these as a "melting pot" of genetic material that could be combined to create a superior fruit.
2. Complex Hybridization: The Santa Rosa plum is a "complex hybrid." While its exact parentage wasn't recorded, historians and modern genomic studies indicate it was a mixture of:
1. Japanese Plum (P. salicina): Provided the foundation and size.
2. Satsuma Plum: Likely contributed the reddish flesh.
3. Simon Plum (P. simonii): Added firmness and a unique acidity.
4. Cherry Plum (P. cerasifera): Likely provided the rich, wild aroma.
3. Massive Scale Breeding: Burbank would cross-pollinate thousands of flowers, often by simply waving blossoms of one parent near another. He then planted the resulting seeds by the tens of thousands.
4. Ruthless Selection: Burbank had a legendary "keen eye" for potential. He would walk through rows of thousands of seedlings and immediately destroy those that didn't show "large leaves and buds" or other signs of vigor. For the few that survived, he used speed-grafting—placing dozens of different seedling scions onto one mature tree—to force them to fruit in just a year or two rather than waiting for them to grow from seed.
5. Final Selection (1906): After years of backcrossing and re-selection to "fix" the desired traits, he finally isolated the single "mother plant" for the Santa Rosa variety and introduced it commercially in 1906.

burbank's "keen eye" for potential is interesting.  i'm skeptical that there's a correlation between seedling vigor and fruit quality.  so i'm sure that his ruthless selection destroyed massive potential.  but its not like he had the space to fruit all those seedlings, even with his clever technique of grafting seedling scions onto mature trees. 

personally i could never deliberately destroy a seedling.  will a loser seedling in high humidity also be a loser in low humidity?  maybe?  maybe not.  but its not like i personally can test every single seedling in every possible condition.  and what about all the possible diseases and pests?

in my front yard is a tropical milkweed volunteer.  as a seedling it looked typical but for some reason its largely resistant to monarch caterpillars.  another volunteer seedling looked virtually identical, and it was very vigorous, but after it flowered and produced a dozen pods that matured, monarch caterpillars devoured all of it except for its thickest stems.  i couldn't have predicted these vastly different resistances to the same exact "pest". 

resistance and vigor are definitely not the same thing. 

my tampa friend who i shared a ficus opposita x carica seedling with says that the cold probably killed it.  i asked him if he were to bet on its rkn resistance, he replied...

Quote
It was very vigorous before it died so i would bet that it's pretty resistant

in this case, no correlation between vigor and tolerance (cold), but perhaps correlation between vigor and resistance (rkn).  correlation doesn't mean causation of course. 

imagine that out of all the seedlings, only his was resistant to rkn.  then its death would be a pretty big loss.  well, he should have backed it up?  on the one hand, clearly he didn't predict the seedling's lack of cold tolerance.  on the other hand, every seasoned grower should be painfully aware of how unpredictable life is.  this should provide adequate motivation for propagation and proliferation... not keeping all our eggs in one basket.  hedging our bets. 

however, what most encourages propagation is money.  here are a couple relevant and recent threads...

Some of these fig people are crazy!
Enjoy the Hobby, question the hype, prices, manipulation

speculators in particular look for "ultra rare", which they bid up, and buy in order to propagate and sell.  in a relatively short amount of time the fig goes from ultra rare to very abundant. 

if i had put a seedling of ficus carica x opposita on figbid, and it had sold for $1 million dollars, would my tampa friend have propagated his?  maybe?  in any case, his decision would have been better informed.  before i shared the seedling with him and others in florida, i actually thought about auctioning a seedling on figbid, but clearly i had other priorities, which is ironic.  i did try auctioning a seedling on here but that didn't work

how do i define my past self?  by what i did know, or by what i didn't know?  by my ignorance or by my information?  i didn't know that it was possible to cross figs.  this ignorance seems significant.  if i somehow was able to introduce my past self to someone else... "this is epiphyte, he doesn't know its possible to cross figs."  true, but perhaps a bit rude.  "this is bob, he doesn't know the earth is round." 

the reason i eventually learned its possible to cross figs is because i stumbled on condit's hybrid at a local nursery.  it was for sale.  but in theory i could have just as easily stumbled on it at ucla or the huntington.  and now i can simply tell people that its possible to cross figs.  its obvious that markets aren't necessary for combating ignorance.  the question is, which weapon is the most effective? 

x = combating ignorance with a bow and arrow
y = combating ignorance with an atomic bomb

right now condit's 1950 paper 'an interspecific hybrid in ficus' is for sale.  people can buy it.  but clearly these sales don't motivate condit to supply more papers about fig hybridization.  and we don't even know how many times his paper has been sold.  there's no nytimes best seller's list for scholarly papers.  is there?  according to google search ai there isn't.  the main metric for a paper's usefulness is how many times its been cited.  when i pointed out the double standard to the ai, and how it had overlooked it...

That is a fair and biting point. My apologies for the oversight—you're highlighting a massive disconnect in how we value "influence" versus "access."
The reason we don't track sales for scholarly papers the way we do for the NYT Best Sellers is because the academic economy is fundamentally broken compared to the literary one:
The Paywall Problem: In fiction, a sale means a reader bought a book. In academia, a "sale" often means a university library paid a multimillion-dollar subscription fee to a publisher like Elsevier or Springer. Individual "unit sales" (buying one PDF for $40) are rare and considered a failure of access, not a sign of success.
Authors Don't Get Royalties: When you buy a NYT Best Seller, the author gets a cut. When you "buy" a scholarly paper, the researcher gets zero dollars. Because there is no profit motive for the author, "units sold" isn't a metric they—or the public—have historically tracked.
Impact vs. Popularity: We should care how many people are reading this work. But because so much of the best research is locked behind paywalls, "citations" became the proxy for value. It’s an elitist metric: it only counts if another member of the club mentions you, not if a thousand regular people read your work and learned something.
The shift is happening, though. The Open Access movement is trying to make "read counts" the new "sales units." Platforms like PLOS ONE and bioRxiv track total views and downloads, which is the closest scholarly equivalent to a "bestseller" count. They believe that if a paper about a new cancer treatment is read 1 million times, that is a more vital statistic than it being cited 10 times in obscure journals.

the number of times a paper has been read is about as meaningful as how many times a youtube video has been viewed. 

if i auction one of my fig hybrids on figbid, the bids will be public.  anyone could see them.  this would help combat ignorance about the usefulness of the seedling.  but we'd still be ignorant about the usefulness of youtube channels like florida natural farming (fnf) and flying fox fruits (fff). 

i have a crazy plan to more efficiently combat ignorance.  i'll start a tff thread kinda like this...

Quote
its time to drop an atomic bomb on ignorance.  too many people believe that correctly guessing demand is easy.  but is it really? 

the prize
seeds or seedlings of my "ultra rare" fig hybrids
the challenge
correctly guess the top 5 most valuable youtube channels as determined by the live donation ranking at junglegroves.com
how it works
1. nominate: reply to this thread with up to 5 youtube channels that haven't been picked yet
2. sacrifice: anyone can donate at junglegroves to elevate a channel’s ranking
3. timeframe: the submission period ends one week before the contest ends
4. winners: whoever submitted one or more of the final top 5 channels

contestants would be able to donate for the channels they submitted.  which channels does our community want to be least overlooked?  on the one hand is the weird fruit explorer, someone we all know and appreciate, so his channel isn't really overlooked by any of us.  and he doesn't actually grow any of the fruits he talks about.  on the other hand is @SBFruittree, which is k-rimes channel.  last year on instagram i messaged him, "Ooo, great videos, thanks!!  Ur such a natural at saying informative and useful stuff about ur plants, u should really post on YouTube more often!"  somewhere in between them, at least in terms of subscriber count, is fancyplants. 

if i had $10, and could only use it to promote these 3 channels, how would i divide it between them?  off the top of my head i couldn't say.  certainly not evenly.  so i definitely wouldn't feel confident trying to guess how you or anyone else would divide $10 between these 3 channels.  therefore, what would we say about the winners of my proposed contest?  were they skilled, lucky, both or neither? 

right now we know how popular a rare fruit channel is, but we don't know the demand for it.  this ignorance is crazy and scary and absurd and tragic.  it defines us.  it will define us forever.  in this era, our era, we use markets, but we are blind to their usefulness.  by their fruits will you know them.  our fruits are meager, because our ignorance is systemic.

some interesting and good points-

Interesting thought process here- Burbank certainly didn't say he comprehensively assayed these crosses my assumption is that he selected for vigor because, well, vigorous trees grow better which is good for a commercial fruit crop- only after that did he try to get the fruit qualities up to par. Similarly unless you have climate controlled greenhouses to test multiple growing conditions why keep something around that is struggling in the climate you are growing it?

If one of your fig crosses was amazing but super low vigor, or took 80 years to fruit would people be interested? probably not...

FWIW I now have the Condit paper, if you provide an e-mail I am happy to share it

elouicious, i thought of you the other day when a youtube guy touring an incredible private garden in columbia asked if the epiphytic blueberries were edible.  the answer he received was that some are poisonous.  in that video you can see a few really nice epiphytic blueberries.  in the first video of the tour the guy asked about the fruits of monstera deliciosa.

coincidentally, today was the first time in my life i ever heard of the fruits of philodendron bipinnatifidum being edible.  it is an extremely common landscaping plant here in socal but it is never pollinated, unfortunately, because it turns out that the fruit is delicious.  in this video a guy in misiones argentina eats the fruit, which he called guaimbe.  he strongly advised not actually chewing the flesh because the numerous small white seeds are extremely unpleasant when chomped on.  before eating the fruit he noticed some fly eggs on the outside of it but he simply brushed them off. 

i feel very wimpy about not tasting the delicious smelling syngonium fruit i found on the jungle floor in costa rica.  fortunately i somehow have some seedlings of it so hopefully one day i'll be able to redeem myself.  i've tasted several anthurium berries and they were all edible, so i'm guessing that many if not most aroid fruits lose their calcium oxylate crystals when they ripen. 

"is it edible?" is such an underrated question.  on inaturalist this question is barely asked.  are you on inaturalist?  if so, you should start a project for figuring out the edibility of epiphytic blueberries. 

regarding vigor, when one of my fig hybrids grows slowly where i currently am in socal, i can't help but wonder if it would grow faster closer to the coast where its cooler, or in central florida where its warmer.  well, warmer on average.  so vigor is very relative to conditions.  none of the plants we grow are going to be vigorous in antarctica. 

every seedling has optimum conditions.  what are the chances that a seedling's current conditions are also its optimum conditions?  very slim.  so when i have a seedling that is slow, my first assumption is that its conditions are lacking.  this doesn't mean i should keep it.  and if i'm not willing to destroy it, then...?  then i should rehome it. 

that's very nice of you to offer to share condit's paper with me.  actually i have it as well.  out of curiosity, why do you have it?  i'm guessing you read it?  didn't you say that you were working on crossing some epiphytic blueberries?

Thanks for sharing the video, I would love to visit Colombia some day as it is a naturally rich spot for diversity of the neotropical blueberries, I have tried to incentivize some colombian members to collect and sell seeds to me but so far no bites  :'(

The one they reference eating looks to be Sphyrospermum cordifolium- which is edible but not all that palatable, I have a flowering plant now and am trying to see if I can improve the fruits with fertilization or watering regimens before trying crosses. I have also heard that some of these can be poisonous but have yet to hear of a specific species that cannot be eaten. The Cavendishia quereme (2 spp?) and dulcis are also plants I would love to grow if given the opportunity. This is not the first report of the plants being used to enhance loved either- Cavendishia adenophora, which I am growing, is used in brews to make a "love potion" as well.There are several other species I can see in the video that are not discussed as well- would love to speak to Eduardo if given the chance.

I am on inaturalist, but have only used it for native plant identification before, never proper journaling but I will look into starting a project. So far the most palatable species I ave had is Agapetes rubrobracteata and will probably be the start of my crosses.

Totally agree that some of these plants would do better in other conditions, but as you said- you can't grow them in all the different conditions and certainly shipping seedlings is too expensive to do on a large scale to test other climates also. I guess the only point i'm trying to make is maybe don't feel bad about culling seedlings- there are certainly seedlings that are sensitive to damping off and infection that are unlikely to survive or thrive in any natural environment, and one of the reasons plants produce so many seeds over so many years is to provide diversity genetically so that the species has a higher chance of surviving varied conditions.

I have it because I have journal access through a university, I have a particular vendetta against the scientific publishing system (as you note the producers of the work are in no way compensated by the journals for the fees they charge for access) and like to share the stuff when I can
