sericea lespedeza
(Lespedeza cuneata (Dum.-Cours.) G. Don)

Overview

Appearance

Lespedeza cuneata is an upright semi-woody forb reaching 3-6 ft. (0.9-1.8 m) in height with one to many slender stems. Stems are often gray green with lines of hairs along the stem.

Foliage

Leaves are thin, alternate, abundant and three-parted. Leaflets have wedge-shaped bases and are 0.5-1 in. (1.3-2.5 cm) long and hairy.

Flowers

Flowering occurs from July to September, when small, creamy-white flowers with purple throats develop in clusters of two to four.

Fruit

Fruit is a flat ovate to round single-seeded pod 0.12-0.15 in. (3-4 mm) wide. Pods are clustered in terminal axils, scattered along the stem, and clasped by persistent sepals.

Ecological Threat

Lespedeza cuneata is an extremely aggressive invader of open areas and out competes native vegetation. Once established, Lespedeza cuneata is very difficult to remove due to the seed bank which may remain viable for decades. Native to Asia and introduced into the United States in the late 1800s, it has been widely planted for erosion control, mine reclamation and wildlife habitat.
