Exquisite ultramarine, loosely spaced blue flowers have a white petal in the interior, essentially the reverse of another native, Delphinium pavonaceum.This is a wonderful native from the lower elevations of Western Oregon and California and this particular group is from a Benton Co. collection. Clumping and up to 4' tall, it blooms May–July in partial or dappled shade. Larkspur attracts butterflies and hummingbirds but keep in mind that it can kill livestock if ingested.
