This little onion is native to low to mid-elevations of the mountains of Northern California. Its range includes much of the Pacific Northwest and southern British Columbia. It grows in typical allium fashion with a whorl of grass-like basal leaves emerging in late winter and early spring. Once the bulb matures, a flower stem ascends topped with an umbel of magenta flowers. Mature allium bulbs will divide with age, forming an independent plant. Over time a clump will form which can be lifted and divided. Strangely, this allium is like many native bulbs in being somewhat difficult to establish. Taper tipped onion prefers a sunny location in well-draining soil.
