Summary of Invasiveness

Top of page

Galega officinalis forms dense thickets and competes with and reduces yields of forage plants. Goatsrue produces a toxic alkaloid, galegin, which lowers blood pressure and paralyzes the central nervous system.

G. officinalis was added to the US Federal Noxious Weed list in 1983 and is regulated in 12 US states (USDA-NRCS, 2011).

Description

Top of page

G. officinalis is a shrubby, herbaceous perennial that can reach 2 meters (6 feet) in height. It is multi-stemmed with alternate pinnately compound leaves. Purple to white pea-like flowers are arranged in terminal or axillary racemes that bloom from June to July. These flowers give way to fruits, which are short pods containing up to 9 seeds.

Distribution

Top of page

G. officinalis is a herbaceous perennial native to the Middle East. In 1891, it was intentionally introduced into the USA for study as a forage crop at Utah State University. When researchers discovered that the plant was unpalatable and toxic to cattle and horses, the research ended but the experimental stands of the plant were not destroyed. Over time, the plant spread following Utah’s valley irrigation systems. It now occupies areas of Washington, Maine, Massachusetts, Connecticut, and New York, in addition to Utah. Goatsrue grows best in wet disturbed areas, including streambanks, low pastures, and ditches.
