Cold Hardy Citrus / Re: Ichangensis froze to death, then bloomed.

19F/-7C seems weak. Any true Citrus ichangensis should be able to take more. I think Ilya said that Citrus ichangensis breaks dormancy quickly and is subsequently more vulnerable to (late) frosts and can be easily damaged at much higher temps than normal. I have never had this with my Citrus ichangensis but it is grafted on Poncirus. There is a fella near Cologne (GER) who has a seed-grown, fruiting tree which he claims is very coldhardy (also, the fruit are rather large and nearly seedless).
