General Information

Goat's-rue has a history of use as a bee plant, forage and medicinal plant (USDA-ARS 2016Footnote 3). It was initially introduced into Utah in the 1890s as a forage plant, but was found to contain an alkaloid toxic to livestock (Tingey 1971Footnote 6).

Since its introduction, this species has infested moist, waterlogged and acidic soils in pastures and old fields in Utah. It is proving difficult to eradicate in those habitats (Lasseigne 2003Footnote 7).
