Lilium occidentale
Also called Eureka Lily
Lilium occidentale is a rare North American species of lily known by the common name western lily. Its species name 'Occidentale' means 'westernmost' and refers to its location along the West Coast. It is native to northwestern California and southwestern Oregon. It grows in coastal prairie habitat, swamps and stagnant bogs with Drosera species, bluffs and sandy cliffs, and seaside spruce forests. This rare wildflower is limited in distribution and directly endangered by a number of environmental factors. It is a federally listed endangered species and it is listed as endangered by the states of California and Oregon.
It is found growing along a narrow 200 mile stretch of coast between Southern Oregon and Northern California usually within sight of the ocean. Its furthest northern distribution is Florence, Oregon to as far south as Eureka, California.
Lilium occidentale grows easily from seed with stratification. It can be easily grown in an artificial type bog or other wetland setting providing its need for constant moisture during the growing season is met. (McRae). There is considerable hybridization with other native lilies, in particular L. columbianum, in areas where the two species grow in close proximity. At some locations the two species grow side by side, with L. occidentale growing in low depressions (drainage ditches) that are clearly flooded during wet periods or periods of heavy rain, and L. columbianum growing just feet away on the steeper slope.(McRae). This leads to confusion with regards to "true" phenotype.
Regardless of its relative ease of culture, Lilium occidentale is a federally protected species under the Endangered Species Act and C.I.T.E.S (Convention on International Trade in Endangered Species of Wild Fauna and Flora) and therefore it is illegal to own or process any plant material (seed, bulbs, leaves, ETC), or sell seed or bulbs without proper documentation and approval of U.S. Fish & Wildlife.
