Native wisteria at Mt. Cuba, Hockenville, DE.

Native wisteria was developed by Longwood Gardens from a specimen sent in from the south of the US by an anonymous person

These wisteria species are hardy in the eastern United States. They bloom in May.  I noticed no fragrance but there may well be such.
