Columbia Onion
Species

    Columbia Onion is a perennial herb, 1-3 dm high and arising from solitary or clustered egg-shaped bulbs with brown or gray honeycombed coats. The 2 sickle-shaped leaves, greater than 5 mm wide and concave in cross-section, arise from near the base of the stem. Pink flowers are borne on 15-24 mm long stalks in a hemispherical inflorescence subtended by 2-3 papery, egg-shaped bracts which arise from the swollen stem top. Each flower has 6 narrowly lance-shaped, petal-like tepals, which are 7-8 mm long, and 6 stamens, which are as long or longer than the tepals.
