    I see this Indigobush once-in-awhile in swampy areas or near a pond in the wild in southeast PA and northern IL. Its native range is from southern New England & New York down into central Florida to east Texas up to southern Manitoba, and there are some spots in the southern Rocky Mountains, some spots in Arizona, and in southwest California, growing in bogs, swamps, bottomlands, and along watercourses or ponds and lakes. Some native plant nurseries sell some for naturalistic landscapes, but I've never seen it sold at conventional nurseries or seen it planted in yards.

    Amorpha fruticosa is a native perennial here in Florida. Desert False Indigo can attain heights to 12 feet; a broad, densely branched, spreading shrub with large, showy flower spikes of many small deep purple blooms with bright yellow anthers. Amorpha in Greek means "deformed" referring to the single flower petal which deviates from the typical blooms of the Pea and Bean family. In appearance the blooms seem to be a tube shape but are actually a single petal, wrapped to form a tube. "False" is because of the poor quality of indigo dye obtained from this plant.

    Desert False Indigo has large showy flowers that attract many pollinators and the foliage acts as a host plant for the caterpillars of the Silver Spotted Skipper and the Southern Dogface Butterfly.
