Amorpha Fructiosa

This shrub, which often forms thickets on riverbanks and islands, can be weedy or invasive in the northeast. Another False Indigo (A. herbacea) has whitish to blue-violet flowers in fan-like masses on top of the plant and gray-downy foliage with up to 40 leaflets. The genus name, from the Greek amorphos (formless or deformed), alludes to the fact that the flower, with only a single petal (the banner or standard), is unlike the typical pea flowers of the family.

Cold Hardy to USDA Zone 4
