State Rank Reason (see State Rank above)
Aquilegia coerulea has been found in scattered locations within montane and subalpine habitats of southwestern Montana. Additional observations have been reported in the Bob Marshall Wilderness, but their identification needs verification. Locations of older and newer observations does not suggest a change in its distribution within southwestern Montana. Threats or concerns for Aquilegia coerulea's viability have not been identified and habitat does not appear to be a limiting factor. Current information on locations, population sizes, and threats for Aquilegia coerulea is needed.

General Description
PLANTS: Herbaceous perennial forbs. Stems grow 20–60 cm. tall. Source: Lesica et al. 2012.
LEAVES: Primarily basal leaves with long-petioles and twice ternate single blades. The ultimate leaf segments are 1-3 cm long. Leaves are glaucous (covered with a whitish-bloom). Source: Lesica et al. 2012.
INFLORESCENCE: An open, leafy-bracted raceme with several, erect flowers. Sepals are 5, petal-like, white to pale blue, and about 3 cm long. Petals are 5, white, smaller than sepals, but expand behind their point of attachment into a nectar-bearing spur. The spur is gently curved and about 3-4 cm long. Source: Lesica et al. 2012.
Montana’s plants are variety ochroleuca.
