Re: Xanthoceras and Sinojackia
Don, I've grown Yellowhorn for the last 3 or 4 years. It hasn't died back since
the first year, it did flower last spring, but it suckers quite a bit, seems to
need constant staking and hasn't seemed sturdy enough to leave our nursery and
try to survive on campus.It is growing in sandy soil along a river bottom that
gets our lowest temps for this area. I am in z.4 but we have had 2 if not 3 z.5
winters in a row. This spring and last have had excellent forsythia flowers, a
sure sign that we had a very mild winter. Steve
