Woody stem, purple flowers that hang off the stem. The flowers looks like sweetpea flowers but the leaves and stem are different.
Hi Clay,
I don’t know where you found this, but I am pretty sure this is Robinia boyntonii, which is uncommon in the NC and SC mountains, mostly. It differs from black locust, Robinia pseudoacacia by its pinkish flowers, and from the bristly locust, Robinia hispida, which also has pink flowers, by the lack of bristles on the stems.
Sincerely,
Steven Hill, Ph.D. Botanist SCNPS
