Sierra onion, dusky onion
The mountains of California and Oregon; also small areas of Nevada and Washington
Mountains, wooded slopes
Narrow, few in number, growing at the base; may be absent when blooms appear
Allium campanulatum is found in medium to high elevation areas (up to 8,500 feet), from the coastal mountains near San Diego north into far south Washington, but especially in the Sierra Nevada, hence its common name of Sierra onion. The single stalks support an umbrel of delicate flowers (10 to 50 heads) with narrow tepals, (usually) strongly pointed at the tips. Most open just a little way, but some spread wide, resulting in a more conventional flower shape. The tepals are pink or purple in color, darker at the base.
