A perennial flowering plant of the genus Amorpha, especially Amorpha canescens, native to North American prairies, with greyish foliage and purple flowers.

Linguistics
Semantic Notes

Dialectal Variation
British vs American Usage
Differences
The plant is native to North America and not common in the UK, so the term is used almost exclusively in American English contexts, such as botany, gardening, and ecological restoration.

In American contexts, it connotes native prairie ecosystems, xeriscaping, and ecological conservation. In British English, it is a purely technical/borrowed term with no cultural associations.
Frequency
Extremely rare in general British English; low frequency in specialised American English (botany, horticulture, ecology).
