According to experiences from grower from Czech Republic, it survived 3 weeks of -7 °Celsius, but the taste is bad, only flowers are big and ornamental.

If you're up for holding a reservation until spring, that's a deal.  :)  I'll take 2 lucs and 2 C. hirsuta.  Just PM me where to send payment.  :)

No payment now, just contact me, when the  appropriate time for shipping come.

Hi,

How old are these plants? You grow inside or put them outside in summer?

Greetings: Ataman

Plants are 3 years old, I grow them indoor in pots, so they grow slowly.


I have interest.  Do you have any other plants or seeds for sale as well?

My only concern is the weather.  I'd have to hope that they kept them warm enough before I could get my hands on them  :(

Maybe some campomanesia hirsuta plants (15€/pot) SOLD OUT.
If you are afraid of the coming weather in the north of Europe, I can reserve some plant, or plants for you, and you can buy them in the better time, in spring or so.

campomanesia hirsuta

In Europe you can buy Sfusato Amalfitano plants from Tintory, but you can not buy the climate to grow such luxurious  fruits  :)
Tintory is also selling Ponzino Amalfitano Lemon that is probably shown on the photo above.

Hello Ilya,
I asked Tintori in the past about lemon Laaz is looking for, from Amalfi coast, and reply was, that this lemon we sell under the name Limone amalfitano ornamentale.

Tropical Fruit Discussion / Banana seeds are tough.
« on: September 14, 2018, 05:39:51 AM »
In 2007, I bought seeds of Musa X sikkimensis "Daj Giant", Ensete glaucum and Musa violacea, some of them I sowed and the rest put in the drawer.
One ensete plant in 2008 from those seeds.:



This year, I decided to clean the drawer  and because I did not want to simply throw old banana seeds to bin I sowed them here and there in pots with plants and....
voilŕ : After 11 years in drawer.

Discussed it here:
http://tropicalfruitforum.com/index.php?topic=11807.msg261361#msg261361
It looks like Ilama forms this fungi like spots often and city water and dry air reinforce it.
I do not know if it is fungi transmitted by seeds, or something with soil, but outdoor conditions with rain water and sun and normal air humidity help to reduce the symptoms and plant does not die.

Sowed the seeds in october 2017, sprouted few weeks ago.

Cold Hardy Citrus / Re: Long term cold hardy citrus breeding project
« on: August 18, 2018, 09:45:20 AM »
Last year I obtained around  400 hybrid seedlings of 5star citrumelo crossed to Morton citrange and Batumi citrumelo. After selection for the absence of poncirus taste of leaves. I have around 50 plants of each cross growing in the ground.
Now I need a good cold winter  ;D to see to what extent cold hardiness  and nasty poncirus aftertaste are linked.

I have a strong feeling, that they are linked to each other. My opinion is that nasty poncirus oil is someting like antifreeze liquid fot the car radiator.
But time will tell .

Cold Hardy Citrus / Re: Yuzu... my new obsession!
« on: August 13, 2018, 10:24:32 AM »
So,

1. it is not strange to buy citrus seeds from seedless cultivar, seedless cultivars have seeds too, but very few, for example 1 seed per 20 fruits.

2. Yuzu does not grow true to type from seed.

3. Because of 2. each village has usually its own cultivar.
Lines are called kei

Important selections are:


1.木頭系(きとう)Kitō-kei (kitō)
2.海野系(かいの)Umino-kei
3.早生種の「山根系」Yamane-kei  やまねゆず(はやしげる)Yamane yuzu (haya Shigeru)
The Yamane - kei was selected in Mr. Yamane 's garden in Anan City.  Fruits are large  and flat.
山根(やまね)
4.平の香(たいらのかおり)Hira no ka (tai-ra no Kaori)
seedling which seems to originate from Yuzu in Kinno village, Naka gun, Tokushima prefecture.
The shape of the fruit is somewhat height compared with the conventional type of Yuzu, and the concave ring around the fruit part protrudes considerably in a disk shape, the peel is yellow orange thick , the fragrance is strong.
5.物部系  Monobe-kei
6.種なしの (多田錦(ただにしき)) Tada nishiki

I was a bit worried because, when seeds arrived in february 2017, there was a frost outdoor. But everything is ok, and after 1,5 year in ground, seeds start to sprout.

Radoslav: Interesting. I've read that some of the less tropical citrus need either a cold period or a dry period - some sort of stress period - to bloom well. Can a dry period substitute for a cold period in terms of pulp coloration or is the cold essential?


To produce good external or internal anthocyanin pigment, chill is required before harvest.
See experiences from Australia for example :
http://www.anfic.com.au/portfolio-view/early-sicily-c1867/
http://www.anfic.com.au/portfolio-view/alkantara-c2191/
To produce good external orange, or yellow colour, non tropical weather is required before harvest too on all citruses.
Some cultivars produce only male flowers if temperture is tropical during flowering.

Not surprised that soilless culture works for them.  :)  But do you know about how their light needs compare to those of the Pavlovsky citrus cultivars?  I know they're famously more shade tolerant than most citrus.  Just trying to get a general ordering of citrus light needs (I'm simultaneously digging through research papers for PPFD saturation values, although that's not exactly the same thing  ;)  )

From my personal experiences, the most demanding citrus plants, when it comes to sum of sunlight and high temperatures to get good fruit are citrus grandis and citrus nobilis, both I consider as tropical, not subtropical species.
Typical marks of citrus fruit grown in deficiency of sunlight and high temperatures are extremely thick albedo, sometimes nearly no pulp, low brix, higher bitterness.
On the other hand, some citruses from blood category need nontropical weather with some hours close to zero celsius and different night and day temperatures to reach good pulp coloration.

17
Thanks for that.  :)  I assume that even finger limes can't approach this level of low-light tolerance?


Finger limes soon will be grown in EU the same way as tomatoes.

Reykjavík is zone 8a, so i guess, it is not easy to get good quality fruit even in greenhouse.


Oh no, we have excellent quality greenhouse fruit, including sun-loving species like tomatoes. The solution is simple: use ridiculous amounts of geothermal / hydroelectric electricity in lighting  ;)  You can see the greenhouses glowing from great distances away**.



Outdoors, though?  Yeah, that's mainly things like root vegetables, some grains, rhubarb, etc.  Nobody is going to be growing citrus as an outdoor plant here  ;)  BTW, our real problem is not our winter lows (which are actually pretty mild), but rather our daily summer temperatures. A typical July high is around ~15° / 60°F. A lot of plants just simply won't grow much if at all in air / soil that's that cool, even though we have tons of summer light. The wind is also a real problem for a lot of plants.  It's normal to get storms with hurricane-force sustained winds in the winter. Several years back we had gusts up to Cat. 5 strength that were really devastating on my land.  To put it mildly, one's outdoor plant selection options are limited  ;)

** - Where we are, light pollution won't be as well tolerated. We're looking at various solutions, from limiting illumination hours to retractable curtains.

Quote
In the first category there is a load of cultivars of bitter oranges and crosses of limon and citron.


In general, if something is to be mostly just for its ornamental aspects**, it needs to be pretty impressive (such as Buddha's Hand). Are there other "mostly ornamentals" that approach that level of "interestingness"?

** - Unless Buddha's Hand citrons are bad from a citron perspective, I wouldn't call them just ornamental. While citron's not an out-of-hand fruit, it makes a great marmelade.  :)  Candied citron is good too.  Of course, out-of-hand fruits are better choices.

Quote
Second category are citruses grown for good fruit. From this category, I recommend lemons, because they are sour and in citruses


Do you have experience with Kannu'on?  I've seen that recommended for its smell, but it doesn't seem to be a very common cultivar.  Are there any specific cultivars you find noteworthy?  And I assume you're referring specifically to C. limon rather than the other lemon-like citruses, such as Meyer?  From what I've come across, C. limon appears to have the nice property of fruiting multiple times or even more or less continuously throughout the year so long as the weather is good.

more sweet means more complicated to grow to reach quality of fruit.
From sweet cultivars the most easy to grow to reach good fruit in your conditions are unshiu mandarins, especially the early cultivars.


I'll need to look up the pollination statuses on these later, thanks.  I assume that this recommendation isn't based on temperature (they'll never experience a cold day in their lives), but other desirable cultivation properties?  Note that if any plant needs chill hours, that's a bad thing; it means either having to vent cold air in, or move plants outside, which would be significant labour.  And/or applying rest-breaking chemicals.  I know that generally citrus doesn't require chill, but I mention this just in case.


1.We have those tomato farms here too. But I guess, you will not put 1000W lamp above each tree in public garden.  :D

2.Except buddha's hand there are some others with unusual shape or colour like:
Citrus auranium "Bizzarria"
https://www.oscartintori.it/prodotto/arancio-bizzarria/
Citrus aurantium "Canaliculata"
https://www.oscartintori.it/prodotto/arancio-amaro-a-frutto-incannellato-o-scannellato/
Citrus aurantium "Fasciata"
http://www.homecitrusgrowers.co.uk/citrusvarieties/fasciata.html
etc.

3. When I said lemons, I meant citruses which normally are sour like citrus limon.
Because sour is sour, there is nothing to spoil because of bad growing conditions.

4. Unshiu mandarins aka satsumas are good choice for sweet citruses, because they accept mild weather and early cultivars are ripe before short winter days start.

5. Last thing is rootstock. For ornamental citruses nurseries like Oscar Tintori use citrus volkameriana, it is not good rootstock for sweet citruses, but ornamental cultivars form nice crown and loads of flowers on it.

Reykjavík is zone 8a, so i guess, it is not easy to get good quality fruit even in greenhouse.
There are 2 categories, ornamental and edible citruses.
In the first category there is a load of cultivars of bitter oranges and crosses of limon and citron.
They are productive and with many shapes of fruit.
Second category are citruses grown for good fruit. From this category, I recommend lemons, because they are sour and in citruses, more sweet means more complicated to grow to reach quality of fruit.
From sweet cultivars the most easy to grow to reach good fruit in your conditions are unshiu mandarins, especially the early cultivars.

Citrus General Discussion / Re: Growing lemons from seed?
« on: May 14, 2018, 07:10:36 AM »
In former Czechoslovakia, it was popular to grow lemons from seeds indoor. It took many years to fruit, but seedlings were adapted to indoor conditions and short days during winters.
Years ago, there was a spot in TV news about one fruiting gapefruit seedling in pot in the Hrebienok ground funicular station right next to the ticket Office. Hrebienok is 1285 meters above sea level. The tree is there for more than 30 years.
Some pictures from that show:






Picture from 2012.


Grapefruit is now under name "Popradsky" expanded in collections.

Fruit trees grown from seed usually take longer to begin producing fruit than those that are grafted.
This is because inducing a slight degree of incompatibility diverts energy from tree growth towards fruit production early on. (Probably because the nutrient to energy ratio for producing fruit is different than growing branches)

?????

What a nonsense.

Grafting is only about mature budwood, nothing else matters.

If you will graft juvenile budwood on juvenile tree, nothing happens.

Cold Hardy Citrus / Re: Japanese kunenbo
« on: April 27, 2018, 09:31:22 AM »
- according to wikipedia it came to Japan during the second  half of  Muromachi Period (1336 - 1573 ), so name has nothing to do with 9. century.
- about cold hardiness, I have never seen it deeper than zone Zone 10a in Japan
(-1.1°C to 1.7°C), so your first step sould be to find plant in open area in colder zone.
Btw. l think, that Kunenbo A is in some collections in EU.

Temperate Fruit Discussion / Re: What citrus is this?
« on: April 25, 2018, 11:34:33 AM »
Move it to citrus section of the forum, here citrus growers can miss the post.

unfortunatley the tree planted in the ground are far from each other so i would need several greenhouses to enclose them all.
Moreover temperatures are constantly high here, it would be a severe challenge to keep acceptably cool inside.
As for now all my trees in the ground are (sigh) unprotected.
I noticed several pomelos affected with greening here in the philippines.
In most cases, non professional growers are absolutely unaware of the disease and its gravity.
Anyway, for some unknown reason (maybe the scorching sun?) noone of the affected trees was severely crippled by the HLB.
Some leaf yellowing, scarce foliage and fruiting and reduced vigour but nothing apocaliptic as i've seen browsing pictures of citrus greening worldwide
I read on web, that according to experiences from Vietnam, pomelo is quite tolerant to greening, it suffers damage, but can survive.

It sounds vert interesting hopefully it has the bright red color of tarocco orange and the woderful taste of clementino :-)

No flowers on my plants now, so I am looking forward for the crop from summer flowering.
Description says, that taste resembles mix of tarocco and clementine.
