The deep blue flowers are arranged in a loose raceme, which may be as long as 50 cm. The flowers are uniquely shaped, with the upper sepal being both blue and helmet-shaped, and forming a hood which hides the upper 2 petals. The lower two petals are small or may be lacking.

Habitat:

Columbia monkshood is a plant of moist open woods and alpine meadows. It is often found along streambanks.

Range:

Columbia monkshood is generally found in mountainous areas from the Cascade Mts east, although it can be found in and west of the Cascade crest in southern Oregon.
