Lead plant (Amorpha canescens) is a perennial, flowering shrub, a wildflower in some states, that grows to 3 feet in height. Lead plant blooms only after it has reached three years of age. Flowers are purple and clustered on 2 to 6 inch long spikes in late summer to early fall. A member of the bean family, lead plant adds nitrogen to the soil. If deer and rabbits frequent your garden you may want to create some sort of protection for the plant. Lead plant is also attractive to bees and grasshoppers and is hardy to United States Department of Agriculture Hardiness Zones 2 through 9.
Grow the lead plant in sandy soil.
Allow the soil to dry completely before watering the lead plant. Do not get water on the foliage.
Deadhead (remove dead flowers) the lead plant as the flowers die. This will encourage the plant to continue blooming.
