General information

Galega officinalis is a perennial herb, 0.4-1.5 m tall. It was introduced to Utah as a possible forage plant, but was unsuccessful and has since infested many acres there. The stems and leaves contain a poisonous alkaloid, galegin, that makes it unpalatable to livestock, and toxic in large quantities. Because of this, it can reduce forage area. Propagation is by seeds, which are spread mainly by water.
