Which is in climate zone 8a.
sure the long hot humid Summers help.
-
I wish to have a few seeds or can buy a seedling to grow in Smyrna, GA. Is there anyway that I can obtain some seeds?
Thanks
-
There was and probably still is a lot of fruit on those trees at the arboretum.
-
I am not a student of UGA and of course have no access to the school arboretum. Is there anywhere in GA that sell citrangequat seedling? I have more interest in the leaves of those trees over their fruits.
-
Lavender 87, I can send you seed from Thomasville, but I don't think it is that hard to find. And it will take up to 20 years for first flowers on a Kumquat-hybrid (not sure, but my Kumquat-seedling flowered this year for its first time ab afte twenty years on a PT rootstock)
-
The arboretum is open to the public. It is called "State Botanical Garden of Georgia"
Stan Mckenzie should have plants. http://mckenzie-farms.com/photo.htm (http://mckenzie-farms.com/photo.htm)

Zitrusgaertner, thank you for your info. It was hard to find, and I have tried even Amazon, Ebay, but none of them had any clue about this citrangequat. I did not realize that it would take 20 year to fruit; however, I only need their leaves for cooking and blending medicine, most citrus fruits can be bought from most stores in US but not leaves.
Thank you for your kindness, I will try to search else where to see if I can order a tree, if not I still love to have a seed to try in my area (Atlanta, zone 7b).
-
hardyvermont, thank you for your useful info. I will try to order 2 citrangequat from that website to experiment in my zone 7 region.
-
Why do you believe that leaves of Thomasville are so special?
-
Ilya11, I did not say anything about the specialty of the citrangequat leaves. I just need some types of citrus leaves other than the trifoliate orange for cooking purposes. Unfortunately, there was none survive in my area (Atlanta) zone 7b beside the trifoliate, so I would like to try something difference.
-
Does anyone has this tree in GA?
-
Keraji-Mandarin is hardier than Thomasville (is't it, Ilya) and has very nice smelling leaves (did not eat them)
-
Zitrusgaertner, do you have their seeds?
-

Kumquat hybrids are usually the fastest flowering per the literature. I have a seedling Citrangequat that took 5 years from seed, which is not long at all. It might have to do with the heat units.
Lavender87, I have a few seeds that have sprouted...

Manfromyard, do you have citrangequat seedlings for sale?
I used to grow lemon from seeds in Vietnam, a tropical region, and it take about 3 years to fruit, still don't know why people claimed that it take 20 years for its first flowering?? I would like to get several 5 years old seedlings if you have a lot extra for sale. And by the way, what did you mean by saying "it might have to do with the heat units"?
-
I was talking about my experience. And I ws talking about Kumquat. Might be that Citrangquat flowers earlier. But if you go far leaves I don't know why you are looking for Thomasville.

I contacted Stan, he said that citrangequat is currently out of stock. I have to wait at least 1 year for him to propagate several.
-
Heat units are just a measure of how hot it gets. The southeast and Northwest are classified as the same USDA zone in some parts. You have 7a to 8b in both sports. But it gets hotter for longer in the southeast. That added energy allows plants to grow faster and fruit to ripen more quickly.
And I don't have a lot of old seedlings. These are basically the ones from this pfall. They just started.
I can maybe give you 1 from last season. You could grow it out fro a year or 2, then plant outside..

I'd appreciate it very much if you can pass to me one or 2. I can stop by your location whenever you're ready.
Thanks

Please let me know the price and shipping cost, or I can stop by to pick it up.

There was nothing special about citrangequat leaves, but I would like to grow a reliable tree that can be leaves harvested anytime of the year, of course except for a few months of winter. Moreover, I also wanna see how their fruits taste.
-
Keraji. Much better than Thomasville. Tastes better, earlier ripe, better hardyness.

Oh really. I have never heard of Keraji Citrus. I did a quick search and found very little info about it. Some people claimed that they are sweet and cold hardy, but no one mentioned how cold it could withstand. Thank you so much for the info.
By the way, do you have their seeds? Can I buy some?
-
I found some extra info about keraji hardiness. People claimed that it could withstand a freezing cold down to 12F which is not reliable in zone 7b/8a in GA. The southeastern part of the US is not that cold but pretty much a horible zone for its unstable winter temprature. in 1985, on the Jan-21st, it was recorded at -8F. And the record low for GA according to Wiki was -29F. No one can predict an upcoming dead winter.
I have always been wishing an opportunity to move away from Atlanta. I used to live in Sanjose, LA in CA and Bradenton in FL. Only 3 states so far, Atlanta seemed to be the worst.

Thomasville will be severely damaged after 2-3 nights at 12F without daytime defreeze. -8F will certainly kill it.
-
Ilya, thank you very much for your info which was like a pointy knife poked into my heart, killing my last hope.
Stanley Mckenzie claimed that his citrangequat has been through a night of 8F with no injury. Wiki also claimed that it could withstand 0F if old enough. I will try to graft citrangequat to Flying Dragon rootstock just to increase its cold hardiness.
My neighbor has 2 old flying dragon trees with a lot of strong fragrant fruits but fruits were sour and some were even bitter, and the tree was so thorny that I was afraid to get my hands too close. I was so excited when heard of citrangequat, but finally it might be another junk? LOL.

These are pics of Thomasville citrangequat in Savanna, GA. Very healthy and tall tree. I’ll try to find a picI took of one in Anniston, AL which is due west of Atlanta, GA.
-
Sorry, can’t find pic of Anniston citrangequat. It got deleted fro my photos. But, anyway, the one in Anniston looked like it had been through the war; tall and not well branched, scraggly with a few fruit on it, alive but not impressive ornamentally. If someone in Atlanta wants a citrus nicer than trifoliata, maybe try Dunstan or Swingle citrumelo. I saw some at the arboretum in Raleigh, NC this fall, and they were beautiful with lovely fruit. I do have pics of them:

I guess the US goverment has stop funding research institutions long ago to continue improving the cold hardy citrus. I think the main reason was to discourage the spreading of citrus species in more cold hardy zone areas.
The US government was trying to reserve the balance of natural environment. That might explain why most of best taste cold hardy citrus species came from Europe. And as I remember there were laws that ban the transportation of certain tropical trees from Florida to Georgia as well, so there should be no hope to rely on the US official research institutions to create a better taste and more cold hardy citrus species which could survive in colder zones.

Stanley Mckenzie claimed that his citrangequat has been through a night of 8F with no injury. Wiki also claimed that it could withstand 0F if old enough. I will try to graft citrangequat to Flying Dragon rootstock just to increase its cold hardiness.
Lavender87,
There is a lot of difference when a large mature plant experience one hour drop to such temperatures, accompanied with day time defrost and more moderate cold that is kept during several nights with frozen soil that is quite common for zone 7 climates.
Also, Thomasville is very robust and strongly growing plant. I have one on its own roots that experienced one night drop to -16C (3F), was completely destroyed, but managed to sprout from the roots.
Fortunately next winter was extremely mild and in two seasons it restored its trunk.
Among hardy citruses available in US Morton citrange is more robust than Thomsville and when fully ripe approach acid orange in taste.

That is also true for Europe, citrus industry is not interested in increasing citrus belt to the North.
Most of the progress is achieved by citrus enthusiasts.
Also, the big difference between Europe and USA is a common practice here to grow citruses for decorative purposes and some interest from nurseries that sell plants produced in Italy and Portugal to the Northern Europe.

Thank Ilya11 for the info

My thomasville and citradia and dunstan survived last winter unprotected but mortan, rusk, nansho dai dai, Ichang lemon all died unprotected.

how old was your Thomasville? Did it get any injury?

My Thomasville is one of my oldest citrus trees, planted 6 or seven years ago. It has reached 10 feet tall once and I’ve tried different methods of passive protection to help it and other poncirus hybrids survive winters. It has lost wood and height by half and twice has died down to the ground but has come back from the roots. Although it it currently two feet tall, alongside a citradia, it has outlasted every other “hardy “ citrus I’ve tried to grow outside here without enclosing it in a plastic tent with a space heater. I’ve replaced Swingle, Dunstan, citradia, rusk, mortan, nansho dai dai, many Ichang lemons, Changsha, twice and all have died completely, but this one Thomasville keeps coming back. Last winter I finally took down the high tunnel I had built over my line of citranges/hybrids and just let the few I had left succumbe to winter; all died but the Thomasville and my last citradia came back from the roots. I’m now foolishly protecting them like I do my fruiting grafted satsumas with small space heaters on thermo cubes under plastic domes when freezing temps arrive. I know now they will never get tall enough to bloom unless I build a 15-20 ft tall frame around them, but I respect their resilience and want to preserve the citradia since I can’t obtain another specimen from anywhere. Woodlanders no longer carries them.

I don't believe you are foolishly protecting them. Its your hobby, and a man needs a good hobby. The best to you and your trees.

Oh, that was sad to be in zone 6b. I admired your great passion on citrus. Do you have any plan to move southward to another state like Florida...?
-
Thanks, Millet. I am after all a “citruholic”! I’ve made some excellent satsuma marmalade this winter for the first time! I’ve found those two satsuma trees I have and protect to the gills produce so much fruit every year, I really don’t need more trees than that, but It’s hard for me to let the other unproductive “from-seed” trees freeze to death. I feel sorry for them.

911311, I was born and raised in Manatee county, FL, surrounded by citrus that grew like weeds without a bit of care. I moved to NC to grow something different like apples, peaches, pears, apricot, cherries, plums, crabapple, Rowan, raspberries, blueberries, paw paw, nearly all of which I was told growing up I couldn’t grow in FL because “it doesn’t get cold enough.” I figured I’d have to give up citrus when I moved to the mountains. Then I discovered a poncirus trifoliata at the Biltmore House in Asheville, NC, and then found McKenzie Farms, SC online, and the rest is cold-hardy citrus history.
