Roemer’s Acacia

Senegalia roemeriana

“This is a prickly, 3-7 ft., round-topped shrub or, more rarely, a small tree to 20 ft. with spreading branches. Branchlets with scattered straight or recurved prickles. Leaves divided into numerous leaflets 1/2 inch long or less. Fragrant, cream to greenish flowers 3/8 inch wide arising mostly from the axils of the leaves are followed by a narrow, leathery fruit. Fruit a brown to reddish, flat, curved pod up to 4 inches long and 1 1/8 inches broad. Young trunks are covered with smooth bark, becoming scaly with age. Twigs are armed with short, curved prickles; hence the common name, Catclaw.”

Roemer’s acacia is a shrub that can grow from 15 to 20 feet in height and has a spread of 10 to 15 feet. It is a perennial, deciduous shrub that prefers sand, clay, gravelly, rocky, or limestone soil types. It requires full sun, and, once established, requires very little water to survive. It blooms in the Spring. Flower color varies from white to green. It provides both nectar and seeds for wildlife.

Leguminosae (Fabaceae)

“Roemer Acacia grows in dry limestone or gravelly soils. In good, deep soil it grows to 15′-20′, although on thin limestone hillsides in Edwards County it is a scraggly shrub of 3′ to 6′. It is drought resistant and fairly cold hardy, as are Gregg and Wright Acacia. Its globe-shaped flowers are a good source of honey.”
