Amorpha fruticosa is a species of flowering plant in the legume family Fabaceae, known by several common names, including desert false indigo, false indigo-bush, and bastard indigobush. [2] It is native to North America.

Description

Amorpha fruticosa is a perennial shrub. [3] It grows as a glandular, thornless shrub which can reach 5 or 6 m (16 or 20 ft) in height and spread to twice that in width. It is somewhat variable in morphology. The leaves are made up of many hairy, oval-shaped, spine-tipped leaflets. The inflorescence is a spike-shaped raceme of many flowers, each with a single purple petal and ten protruding stamens with yellow anthers. The fruit is a legume pod containing one or two seeds. [4]

Distribution and habitat

The native range extends through much of the United States and south into Mexico. [5] Its native habitats include stream and pond edges, open woods, roadsides and canyons. [3]

The species has escaped cultivation elsewhere and is present as an introduced species in Europe, [6] Asia, and other continents. It is often cultivated as an ornamental plant, and some wild populations may be descended from garden escapes.

Flowers

Chemistry

6'-O-β-D-glucopyranosyl-12a-hydroxydalpanol, a rotenoid, can be found in the fruits of A. fruticosa. [7] Several members of the amorfrutin class of compounds have been isolated from the fruits. [8] Amorfrutins as well as other secondary metabolites from A. fruticosa have displayed favorable bioactivities counteracting diabetes and the metabolic syndrome. [9]

Ecology

It is a larval host to the clouded sulphur, gray hairstreak, hoary edge, Io moth, marine blue, silver-spotted skipper, and southern dogface. [10] The plentiful seeds are a food source for bobwhite quail. Both bees and butterflies use the flowers as a nectar source. [11]

Cultivars

  • 'Albiflora', with white flowers
  • 'Crispa', with curled leaves
  • 'Lewisii', with narrow leaves
  • 'Pendula', with arching branches, forming a dome shape
