The currently accepted scientific name of low larkspur is Delphinium bicolor Nutt. There are no recognized subspecies, varieties, or forms. Matthews, Robin F. 1993.
Low larkspur is toxic to cattle and causes some losses in the spring and early summer.
However, it dries rapidly and senesces after seed set. Low larkspur is less toxic and more palatable to sheep than cattle. Low larkspur is a native, perennial forb with an extensively branched fibrous to slightly fleshy root system. Fruits are many-seeded follicles. It is found on gentle to steep slopes.
