Western larkspur (Delphinium hesperium ssp. hesperium)

The western larkspur or foothill larkspur (Delphinium hesperium ssp. hesperium) is a showy wildflower that is both native and endemic to California. Despite the beautiful appearance, however, this perennial herb contains toxic alkaloids, rendering it highly poisonous to humans, cattle and many other animals.
