Answer
Dear JuliaB, good morning. You have photographed Amorpha fruticosa (false indigo-bush), a non-native woody plant that is native to the United States (but has spread to the northeast and is introduced here). The dark purple flowers with only one petal developed (banner petal) is diagnostic for this member of the legume family. Best wishes.
