A loose, airy shrub which often forms dense thickets. grey-green pinnately compound leaves. A nitrogen-fixing member of the legume family. Spikes of tiny, purple to dark blue flowers with bright yellow protruding stamens make for a stunning flower – and the bees thinks so too! Similar in appearance to lead plant (A. canescens), but is much taller and prefers to keep its roots moist. Spreads by seed-seeding and suckers. Great for naturalizing.
Larval host. Attractive to wildlife. Special value to native bees.
