Today I found a Redbud (Cercis canadensis) tree covered with dried seedpods. I grabbed a dozen and will start a few trees this winter.
I like to eat the flowers, pods, and dried seeds. The flowers are a welcome sight in late winter, the tree is covered in purple blooms. Dried, the blooms are a nice addition to tea. As the pods form, use much like snow peas. I harvest a pound or two of dried seeds for cooking like lentils.
I admit that I rinse the dried beans before cooking and drain.
