Camassia
Camassia is a genus of plants in the asparagus family native to Canada and the United States. Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth.
It grows in the wild in great numbers in moist meadows; they are perennial plants with basal linear leaves measuring 8 to 32 inches (20 to 81 cm) in length, which emerge early in the spring. They grow to a height of 12 to 50 inches (30 to 127 cm), with a multi-flowered stem rising above the main plant in summer. The six-petaled flowers vary in color from pale lilac or white to deep purple or blue-violet. Camas can appear to color entire meadows when in flower.
