Oxytropis campestris is a plant native to the western United States and Canada, sometimes grown as an ornamental plant. The plant grows perennially, with an acaulescent forb reaching 20 to 50 cm in height and has a taproot. It is found in prairies, woods, and meadows, and prefers gravelly and rocky slopes, where is grows most abundantly. The plant has numerous variants.

It blooms flowers from May to July. These are racemes that are capitate or oblong, 4 to 15 cm in length. The plants have 8 to 32 flowers that rise from a scape. The actual flowers have five lobes and form a calyx tube. They are of a cream to yellowish color, but sometimes of pink, blue, or purple, with hairs that are usually black. The keel petals are pointed, and often have purple blotches. The plant also produces fruit which matures from July to September. These are legumes which are oblong-ovate 1.5 to 2 cm in length. They are mostly sessile and dehiscent from the tip. The fruit has membranous and contains many seeds.

Leaves grow alternately in a pinnate fashion and are usually 8 to 40 cm long. The leaves are dimorphic, with primary leaves short ovate leaflets, and secondary leaves with 11 to 33 leaflets. These secondary leaflets are 1 to 2.5 cm long.

This plant is poisonous and may cause loco disease in livestock. From this it derives the common name field locoweed or some other variations. It is therefore worthless as food and is consumed only when other forage is not available.[1]
