Q.Hi, I brought home a green seed pod from a pepper tree here in Ca.
Not sure if this green pod, which has what looks like little seeds inside is what I plant to grow a pepper tree. Could you please send any info? Such a pretty tree with lots of shade. Someone said it’s the berries that grow. Thank you So much,? Cheryl

Hi Cheryl, Pepper trees don't produce legume seed pods like that. I believe what you have there is mimosa (silk tree, Albizia julibrissin), very common in your area and a very good tree for the climate. You can try to propagate from seeds, but if I were you I would buy a desirable variety from a garden center. There are some good nurseries in that area.
If you really want a pepper tree, you need to differentiate which species. Peruvian pepper (aka California pepper, Schinus molle) is also a great tree for Danville area, as is it's cousin Brazilian pepper (Schinus terebinthifolius).
