Erythronium hendersonii, Henderson's Fawn Lily, is a member of the Lily family that is endemic to southwest Oregon, and barely reaching into Northern California. It can be locally very abundant within its range which is basically restricted to the Rogue River, and Applegate River drainages in Josephine County and Jackson County in Oregon, and barely into northern Siskiyou County in California. It blooms early in the southern part of its range starting in February, with some locations carpeted by E. hendersonii in the thousands in March, where it often blooms with Dodecatheon hendersonii. It blooms at higher elevations through May. It is most abundant in dry, open woodlands of Ponderosa Pine, Garry Oak, and Madrone. E. hendersonii has a pair of mottled leaves, and its scape can bear up to eleven blossoms, but more commonly 1-4. The flower color is distinctive among all western North American Erythroniums. The color of the recurved petals varies from a deep velvety purple, to lavender. The base of the petals is dark purple, and surrounded by a tinge of white or yellow. The stigma is unlobed to shortly three-lobed, and the anthers are purple to brown.
