[Wikipedia] Range, Pollinators, Threats: Lilium rubescens is an uncommon species of lily known by the common names redwood lily and chaparral lily.[2] It is native to northwestern California and southwestern Oregon, where it is known from the Coast Ranges from Lane County to Santa Cruz Counties.[3] As its names suggest, it is a member of the flora in redwood forest understory and chaparral habitat types. The flowers are probably pollinated by bees and the pale swallowtail (Papilio eurymedon).[4][5] This plant is threatened by a number of factors, including development, logging, non-native species, road maintenance, and horticultural collecting of the bulbs and flowers.[6] (link added by Mary Ann Machi)
