Coast Trillium

Coast trillium (Trillium ovatum) is a spring-flowering perennial herb in the family Melanthiaceae, native to moist, shaded forests of western North America from British Columbia and Alberta south through the Pacific states to central California and east to Montana and Idaho. It grows in mixed conifer and deciduous forest understories, redwood forest, riparian woodland, and coastal range foothills, typically in deep, humus-rich, well-drained soils. Like all trilliums, it produces a whorl of three broad leaves, a single three-petalled flower that opens white and turns pink to deep rose with age, and takes many years to reach flowering maturity from seed. Seeds are dispersed by ants (myrmecochory) attracted to the oil-rich elaiosome attached to each seed. Coast trillium is assessed as Least Concern by the IUCN, though it is a legally protected plant in some US states due to its slow reproductive rate making populations sensitive to disturbance. Illegal collection from the wild for horticulture remains a concern. It is one of the most beloved wildflowers of the Pacific Northwest and is widely cultivated in woodland gardens.
