Amorpha nana (Dwarf false indigo)
Wasowski, Sally and Andy
Fragrant indigo-bush is a low-growing shrub, 1-3 ft. tall. Its finely textured, pinnately compound foliage gives a cloud-like appearance. Dense, terminal racemes of purple, pea-like flowers with showy, orange anthers are showcased against the bright-green 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.
