Does anybody know where to buy Dimicello and TaiTri?
Is there something to read about in the internet?
I got aware of TaiTri because it has withstand -17°C (1,4°F) for 2 weeks without protection in winter 2011/12 in a private collection in Germany.
This winter was really hard.
If there is something to write about, I am eager to hear about.
Thank you!

I have to do an update

i checked weather charts for the winter 11/12 is was more 2 weeks of -12°C (10,4°F) with lows to -17°C for 1 or 2 nights.
I can`t judged it, but it is still quite cold.
This winter killed citrumelos and other hybrids which survived for up to 10 years until then.

I have seedlings of both plants. But they are very small and they are probably not the original sorts because they are seedlings from monoembryonic seeds.

the mentioned Taitri is also a seedling, so probably also not the true TaiTri like yours.
Where do you get them from?
