I have two grafts one on pure poncirus and one on tai-tri. The tai-tri grew vigorously.
So far both grafts look alive in zone 7a after lows of 1f and 5f. The one grafted on pure poncirus, 2 years old, grows very slow.
After 1 year the graft on tai-tri is twice the height.
It's said to be a chimera of flying dragon and satsuma, the lanky habit probably comes from the flying dragon. I will update more in the late spring to be sure that they are actually alive.
