Please help keep TSO growing!

IDS Trees and Shrubs Online has become a fundamental source of reliable information about cultivated woody plants, freely available to everyone, everywhere. We hope you find it useful.

For the first time we are asking our users if you could support us.

If everyone who uses TSO during May 2026 gives just £10, we would cover our costs for a whole year, enabling us to accelerate our work.

A low, deciduous shrub about 2 ft high; stems branching, and having little or no down. Leaves pinnate, 2 to 4 in. long, with eight to thirteen pairs of leaflets and an odd one; leaflets 18 to 38 in. long, oval or obovate, nearly glabrous. Flowers purple, fragrant, very closely set in cylindrical terminal racemes 1 to 2 in. long. Pod one-seeded, 15 in. long, glandular.

Native of eastern and central N. America; introduced in 1811. Although some­what similar to A. canescens in foliage, it is really very distinct. It is a true shrub, and has little or none of the grey down so conspicuous in A. canescens; its flower-spikes are also much shorter and not clustered. A rather dainty plant, but scarcely known in gardens nowadays.
