I'm not very confident even the rare seedling will show much more cold hardiness than its parents.

(Unless that seedling originated from a heterogenous hybrid involving cold hardy hardy cultivars)

   As I said, we were impossible to select the correct evolved seeds because not all the seeds from a crop would have equal chance to germinate and to prove itself as a worthy one.

   Hybridizing is the only reliable way to improve the quality at this time; however, even inside those fruits from hybrid trees there were self mutated seeds with the quality we wanted, but those rare evolved seeds again might have landed in our trash can.

 Most of trifoliate orange rootstocks used were created from cuttings and of course they were much weaker than trifoliate orange roostocks which were grown from seeds. That might explained pretty well why even grafted citrus trees on trifoliate rootstocks from nursery were usually less cold hardy than the one grown from their own seeds.

  Trifoliate orange is a very slow-grow species, so it is much quicker to multiply by cutting branches from a matured tree than germinating seeds; and that is why people rarely used trifoliate rootstocks from seeds. In normal condition, it would take at least 3 years before a seed-grown trifoliate seedling to qualify as a rootstock, but it only take 8 months to a year to get a ready-to-graft rootstock if we use a cutting from a matured trifoliate orange tree.

  Moreoever, the grafted part often requires at least 2 to 3 years to fully unify with the rootstock it was parasitized on. Most of growers have made the same mistake when they were too hurry in testing out their grafted citrus outside when the grafted part and the rooststocks did not actually unifiy yet, and soon claimed that their citrus from seeds are more cold hardy than the grafted citrus on trifoliate rootstocks.

  Don't use naked eyes to hastily judge the grafting joint. It might look pretty good as if it was 100% succesfully unified, but in fact the rootstock and the grafted part were still adjusting over time and would take years to really accept each other as their own.

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

Hey guys looking to purchase some Standard Trifoliate and Flying Dragon seeds.Thanks

  I have some extra if you want some.

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

   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.

Zitrusgaertner, do you have their seeds?

  Does anyone has this tree in GA?

hardyvermont, thank you for your useful info. I will try to order 2 citrangequat from that website to experiment in my zone 7 region.

  I am looking to get seeds or seedlings of the citrangequat. Please let me know if anyone has some.

 Thanks

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.
