About Allium campanulatum S.Watson
Allium campanulatum, commonly called dusky onion, grows from a gray-brown bulb 1 to 2 centimeters wide. This bulb may produce tiny rhizomes that grow small daughter bulblets. It has a stout stem, and usually bears two long, thin leaves that wither before its flowers bloom. An inflorescence holding 10 to 50 flowers forms at the top of the stem. Each individual flower measures 0.5 to 1 centimeter wide, and is most often pink or purple, and less frequently white. Every tepal has a dark-colored base. Tepal shape varies widely, ranging from narrow and sharply pointed to spade-shaped. The anthers are purple, and the pollen is yellow. This species flowers from May through August.
