Prairie Lupine (Lupinus lepidus lepidus)

Prairie lupine is a widespread and variable species in much of the North American west. All parts of lupines are toxic, especially spring foliage, flowers, and fruits. Lupine consumption by pregnant females can cause birth defects. Cows and goats that eat lupines can pass toxins through their milk and cause deformities. Death from lupine poisoning is rare among humans but livestock that eat lupine in great quantities may die. Photo from near Ellensburg Washington. April 2000
