I ? yesterday but no answer. I live in zone 9a according to your chart. First planted in large pot. and set in NE area on my lot.
Didn't seem to flourish. after 1 year. Landscaper took it out of pot and planted it in ground at NE corner of home. plant about 2.5 feet tall very few leaves. has been in this location aprox 1 year. have see no change. need help.

That's odd ? It should be growing like gangbusters.
If it's not root-bound.
It probably needs more water.
