 Wyoming is host to many beautiful wildflowers. The native larkspurs with their vibrant blue to purple colored flowers are no exception. Larkspurs can be separated into three main groups based on plant stature. Low, plains, and tall larkspur occupy varying habitats and climatic conditions in Wyoming. These wildflowers are in the Delphinium genus, same genus as larkspur flowers found in many landscapes and gardens. These gorgeous plants add stunning color to Wyoming landscapes, yet they hold hidden dangers. Larkspurs are high in toxic alkaloids. These alkaloids are poisonous to many species of livestock. Cattle are most often the victim of larkspur poisoning, while sheep and horses may be poisoned occasionally. Larkspur species are often misidentified and confused with other native wildflowers, specifically lupine species. Carefully examining the leaves is a solid method for differentiating the two genuses. Larkspur wildflowers receive their name from the spur on the back of the flower. This is yet another way to help identify this plant in the wild.
