Delphinium glaucum
is a species of larkspur known by the common names Sierra larkspur, mountain larkspur, and waxy pale larkspur. This wildflower is native to western North America from Arizona to Alaska. It grows in moist mountainous environments, such as riverbanks and meadows. This plant sprouts one to several tall, stout, pale green erect stems which may approach three meters in height. The lobed leaves are generally found only at the base of the plant. The top of the stem is a large flower cluster which may itself be over a meter long. It usually contains over fifty widely spaced flowers, with each flower on a pedicel a few centimeters long. The sepals are flat and extend to the sides or point forward. The sepals and petals are dark blue to deep purple, although the top two petals may be lighter in color to almost white. They may be somewhat wrinkly. The spur is about two centimeters long.
