that tree is looking dapper!
are there two scions on the one tree?
and are you letting the imbe grow at all, or knocking off all the suckers?
it looks very close to fruition, and once they start blooming, it seems like they keep going for a while, mine is setting all sort of fruit, and still has blooms coming on....i counted about 8 fruits set so far, although a few had fell off prematurely already
Here is my Luc's. I grafted scions from Adam onto a cut back Imbe(g. livingstonei) back in June 2017. It is currently 6' or more and in what seems to be a near-constant flush. I'm hoping the large Imbe's maturity and root system will push it to bloom sooner rather than later.
