I have from the Southeast Citrus Expo 2005 a Tai Tri . Because I
speculate on winter hardiness I want to know whether it is from seed of
Poncirus or from C. taiwanica . Although we have no winter up to now
it lost all leaves like Poncirus trifoliata .
I think that indicates a (Poncirus trifoliata x C. taiwanica) = Tri -Tai
A Tai Tri seed from a hp C. taiwanica = Tai Tri
will be less winter hardy ???
Who owns a C. taiwanica x P. trifoliata and experienced winter hardiness ?

I can tell you this. Tai Tri is (Poncirus tifoliata x Citrus taiwanica.)

Hallo Jost,

if your tai-tri tree is flowering and is giving fruits, can you send me some seeds?
I'll pay for the seeds and postage.

I have a tai tri and never had any problems with winter hardiness. I do not know if the seed originated from a poncirus or taiwanica fruit. The lowest temperatures mine has seen was about 13 degrees. It does stand out amongst my other citrus trees in that it is the first to enter a dormant state by shedding its leaves very early. I would imagine that this tree could handle at least a few more degrees of freezing and prolonged freezing because of this fact. My regular trifoliate and flying dragon trees currently still have all of their leaves but my tai tri is already bare. Mine has bloomed the last three years but has yet to set any fruit so I am unable report on its flavor.

G, you should try spraying the tai tri blooms with GA3 to set the fruit. - Millet (459-)

You're right Millet. I do have some GA3 and spray other blooms but seem to always forget to spray that tree. I guess I always assumed that the pollen from all the other citrus in the yard would take care of it but no dice so far. I'm gonna try and make sure I do it next spring.

this is an old thread but it might be for some interest...
I read about a grower in Germany that his taitri seedling withstand 2 weeks of frost around -12°C (10°F) with lows to -17°C (1,4°F) without protection the same frost killed old Citrumelos.

this plant is a seedling of TaiTri from Dr.Inhulsen...
