Field locoweed is a perennial wildflower of prairies, meadows and rocky slopes in cool northern and mountain regions, with yellowish flowers and pinnate leaves. Grown mainly as an ornamental in cool climates; it is best kept in the ground rather than as a container plant.
Oxytropis campestris, the field locoweed, is a plant native to Northern Europe, the mountains of Central and Southern Europe, the Northwestern United States and all of Canada, sometimes grown as an ornamental plant.
It is found in prairies, woods, and meadows, and prefers gravelly and rocky slopes, where it grows most abundantly. The plant has numerous variants. It is a larval host plant of the small blue butterfly
The Oxytropis campestris plant is poisonous and may cause loco disease in livestock. From this it derives the common name field locoweed or some other variations. However, Mountain goats eat it freely.
