Allium tolmiei

Allium tolmiei Baker at the Lawrence Grassland Preserve (Nature Conservancy) near Shaniko, central Oregon, flowering in mid-May. This small onion grows in so-called biscuit scabland, a type of terrain featuring raised mounds of soil surrounded by "moats" of small to medium-sized rocks, and patches of similar rock. It grows only in the rocky spots, surrounded by sagebrush scrub in the deeper soils. Height: 10-15 cm. Photo by Jane McGary.
