USDA Symbol: NOBI2
USDA Native Status: Native to U.S.
This early spring flower is one of the first to appear on lawns, meadows, or roadsides throughout the state. Often it blooms again in the fall. It grows from a bulb and looks much like the wild onion, but has fewer and larger flowers on long stems and lacks the onion odor. The leaves are all at the base of the plant, about 1/8 inch wide, but often quite long, 4–15 inches. The white flowers have 6 tepals with a green to brown stripe, and 6 stamens. Individual flowers are 1/2 inch across and grow in loose clusters on stalks 8–16 inches tall.
