Aquilegia formosa ranges in height from 30 to 100 cm. The stems are pubescent above with the leaves glabrous or pubescent on either surface. The flowers are nodding. The sepals are red, 10 to 25 mm long, and perpendicular. The blades are yellow, very short, 2 to 6 mm long. The spurs are red, 10 to 20 mm long and straight. The stamens extend beyond the blades.

Aquilegia formosa is found growing in moist areas in forests, woodlands, alpine and subalpine meadows.
