Caimito will not fruit in SoCal.
I got one, the purple kind, a few months back, just because I love the fruits. Going in knowing that the chances of getting fruits are slim to none, I still bought it, just to see it growing. Today I spoke to Champa nursery in El Monte, CA. They confirmed that it will not fruit, they tell this to all their Caimito customers. Oh well, the tree still looks good in the pot, though. 8-)) I'm wondering if it can fruit in So Florida.
