Description

The dusky onion, Allium campanulatum, grows from a gray-brown bulb one to two centimeters wide which may extend tiny rhizomes and produce small daughter bulblets. It rises on a stout stem and has usually two long, thin leaves that wither before the flowers bloom. On top of the stem is an inflorescence of 10 to 50 flowers. Each flower is half a centimeter to one centimeter wide and is pink, purple, or less often white, and each tepal has a dark-colored base. The tepals are variable in shape, from narrow and very pointy to spade-shaped. Anthers are purple; pollen yellow.[6][7]
