Allium unifolium (One-leaf onion) - Native California bulb that forms clumps of grass-like slightly flattened 16 inches tall leaves with taller stalks bearing an umbel of 1/2 inch long lavender pink flowers from late May into July with papery tepals surrounding developing fruit that prolongs the display. Plant in full sun in most soil types - does particularly well in clay soils. Irrigate in spring (if natural rainfall is light) to early summer - allow to go dry when dormant. Allium unifolium is native to moist grasslands along forested and chaparral areas along the coastal ranges of California from Humboldt County south to San Luis Obispo County. The specific name "unifolium" and common name One-leafed onion is misleading as there are usually 2 and sometimes 3 or 4 leaves instead of one as these names would imply.  This description is based on research and observations of this plant as it grows in our nursery, in our nursery garden and in other gardens that we visit. We also incorporate comments received and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Allium unifolium.
