They are all over Nor Cal. I find most of the seedlings (sold as ornamental) taste great. I have two named varieties and two seedlings and I like them all. Enjoying them more than my passionfruit right now (although I've been eating those for two months so it's a law of diminishing returns I think...)
Hi, our 3 trees are flowering right now, this is one from the frontyard:
the petals are exquisite, I agree; a friend tried them and he liked them a lot too.
the last season we tried fruits from 2 of these trees and were very tasty; this season we will try fruits from another one on the backyard too that had not fruited yet.
Also, a man gave me feijoas from an unknown tree (bigger fruits) and they were horrible; so, it's true they vary a lot from seedling to seedling.
Very easy to grow from seed, I sow almost 60 and now I have 30 happy little feijoas growing here; and sometimes they were neglected...
