Description

Locoweed is a genus of 611 species of flowering, herbaceous perennial plants in the bean family and native to most of the northern hemisphere. It is often found in dry prairies. The plants tend to be hairy and produce showy racemes of white, pink, yellow, or purple flowers on leafless stems. The leaves of most species are green and basal.

Locoweed does well in sandy or loamy soils that are well-drained and occasionally dry, and sited in full sun. These plants do not transplant well, but can be grown in a pot and then planted in a permanent spot when still small.

This plant is toxic to grazing animals, especially cattle and horses. Some species of Locoweed have a symbiotic relationship with Rhizobia, a soil bacteria. The bacteria forms nodules on the roots of Locoweed and fixes atmospheric nitrogen. Without the nitrogen, these plants may fail to flourish.

Diseases, Insect Pests, and Other Plant Problems:
