check out this one...I got from a fruit collector in PR.
the leaves of this Plinia aureana look much different than any of the others that I have (maybe 3-4 other varieties)
the tree was very hard to establish..I have seedlings the same age that are more than twice the size.
it took a while, but the trees finally grew out of their chlorosis, and started to get happy.
I still have to drench them with chelated Fe occasionally.
