Hello all,
The other week I picked up a bean from a tree near our library. It had a ve lvety surface. It had been on the dinner table for the past week or so. Ton ight when we were having some snacks all a sudden it exploded with a crack and spilled its seeds into the kitchen!
We first heard the noise but couldn't figure out what exploded. Then saw th e pod split into half.
What is this plant? Does anybody know?
Picture is here:
Thanks,
(I think I am in Sunset zone 15.)
