Looking for Tephrosia virginiana...

We are trying to collect seed from Tephrosia virginiana, commonly known as goat's rue ... a densely hairy perennial herb growing erect, but only 1 to 2 feet tall.  Leaves are alternate and pinnately compund, flowers are pea-like with yellow, cream, and pink coloring. Flowers of T. virginiana are on shorter stalks than T. spicata.

We are interested to know if the pods (densely hairy) are still intact with seeds inside... flowers from May to June and fruits during July through October.

Tephrosia spp. should be growing in dry, open woods and the best places to collect seed would have been burned this past spring.

Please let us know if you have a nice clump we could collect for our common garden study!
