After trying to find this species for about 3 yrs, I kept getting the same plant, B. armeniaca, mislabeled as the true Peanut butter fruit (B. argentea).
It turns out that B. argentea is much harder to find.
After locating the real plant, I'm curious to see how it performs in FL.
I've read that these Bunchosia species (armeniaca and argentea) both come from areas that have higher elevations. I'm wondering if it might present a similar problem that the cherimoya does, where the plant grows wonderfully, but has trouble making fruits at low elevations.
I wonder why B. argentea is so obscure, especially if its a superior fruit? The B. armeniaca isn't hard to locate, and grows well here in FL, so maybe that's a good sign.
