Delphinium trolliifolium, Giant Larkspur new 12–18" tall clumpExquisite, ultramarine, loosely spaced blue flowers have a white petal in the interior, essentially the reverse of another Western native, Delphinium pavonaceum. This exquisite native is from the lower elevations of Western Oregon and California, and this particular group is from a Benton Co. collection. Clumping and upright, it blooms late spring mid summer in partial or dappled shade. Larkspur attracts butterflies and hummingbirds, but keep in mind
