Malpighiaceae, Bunchosia argenta, peanutbutter fruit
Bunchosia argentea, or the peanut-butter fruit, is native to Panama and tropical areas of Northern South America. The fruit is mostly eaten fresh, also used to make jams and juices. Its taste and smell are very similar to that of peanut-butter, thus the name.
I remember hearing somewhere that the seeds could be toasted and eaten. Not completely sure about that.
A lot of my year-and-a-half-old trees are flowering and fruiting in five gallon buckets. I’ve grown them from seeds and cuttings. Cuttings can be difficult. I have a few air-layers going right now. I’m pretty sure that will work too.
