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.  The information on this page is based on research conducted about this plant in our library and from reliable online sources. We also take into consideration observations of this plant in our nursery crops, as well as of plants growing in the nursery's garden and those in other gardens we visit. We also will incorporate comments that we receive from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Allium unifolium.
