North America , fromTexas east toFlorida .These woody-based shrubs grow from 1-3 m (3 to 10 feet) tall. It is usually much branched in the upper portion. Branches are thin and widely spreading. The medium green leaves are alternate, deciduous, and pinnately compound. There are typically 12-24 leaflets, and occasionally as many as 60 are found. Each leaflet is oblong shaped and 2-3 cm (about 1 in) long. The orange-yellow, pea-like
flower s occur in a droopingraceme on a long stem. They are often found with red lining. The seed pods are four-sided, four-winged, and about 10 cm (4 in) long. The peas rattle inside, giving this plant its common name of Rattlebush. Inside the pods, theseed s are separated by transverse partitions.These plants flower from May to October, usually retaining many of the seed pods, which remain attached until the plant dies back to ground level for the winter.
This plant prefers moist
soil s of ditches and frequently-inundated meadows, as well as depressions and the open edges of lakes, ponds and streams.The seeds are
poison ous, containing the toxinsesbanimide . Animals raised with the plant learn to avoid it because of the foul taste of the green and flowering plants. However, naivecattle ,goat s orsheep placed on pastures containing dried plants in late fall and winter are frequently poisoned. Sick animals often die within 24 hours.This species is named in honor of the Scottish-born naturalist
Thomas Drummond (1790-1835). Other common names include Sennabean and Drummond Sesbania.References
