Sierra larkspur
Delphinium glaucum
Delphinium glaucum is a species of "tall" larkspur known by the common names Sierra larkspur, mountain larkspur, and glaucous larkspur. Although Ewan, in his survey of North American Delphiniums, treated D. glaucum and D. brownii as two separate species, some taxonomists now seem inclined to treat D. brownii as a local form of D. glaucum. However, the matter does not yet appear to be completely resolved. This wildflower is native to western North America from Arizona...

Description
D. glaucum is a "tall" larkspur, which sprouts from one to several tall, stout, pale green erect stems which may approach 3 metres (9.8 ft) in height. The lobed leaves are generally found only at the base of the plant. The top of the stem is a large inflorescence which may itself be over 1 metre (3.3 ft) 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.
Toxicity. Larkspurs have long been associated with livestock poisoning in North America, and D. glaucum (under the name D. brownii) has caused problems in the rangelands of Alberta, in western Canada.
