Description
Perennial, flowers from May to July. A creeping plant with compound leaves. Numerous leaflets are oval and covered in hair. Flowers are 1/4 to 1 inch long and orange-red. Many seeds in bladder-like translucent pods.

Impacts
This plant was introduced from Asia and is commonly found in western states in irrigated fields and moist soil in waste places along roadsides and fences. It is a potential threat to grain- and alfalfa-growing areas. The seed is a contaminant in alfalfa seed production; it is the same size, shape and weight, making it impossible to separate.
