JOINT VENTURE X (ZERZURA x JEHOSAPHAT'S RELIANCE) maybe. This was the only
one that suggested the pollen parent given might be correct.
Adam, these were very uniform in height at 27' to 30'. I expect they won't
be that height in future years. Here, after maiden bloom, things tend to be
downsized. Once they are no longer being treated as seedlings, they have a
leaner diet due to being dependent mostly on nature to give them H2O. My
best guess under my growing conditions is that they'll settle out to the
18" - 24" range in height.
