Lespedeza–commonly called bush clover–is a woody-based perennial with arching branches of blue-green leaves that bear drooping 6-inch clusters of rose pink, sweet pea-shaped flowers in late summer.
Lespedeza can endure hot, dry sites and soil of low fertility. It can grow to 6 feet (1.8m) tall. Lespedeza grows rapidly; flowers appear on new growth. Lespedeza is an excellent late-flowering plant for a mixed shrub border.
Cut Lespedeza to the ground in late autumn or early spring; new growth will appear in spring.
Lespedeza is a genus of about 40 species of annuals, perennials, and small subshrubs. Lespedeza is native to meadows and grasslands in East Asia, Australia, and North America.
