Trillium albidum
Also called Freeman's Trillium, Sweet Trillium, White Toadshade
Trillium albidum is a perennial woodland wildflower from western North America that grows from underground rhizomes and bears a single fragrant, stalkless white flower above three large leaf-like bracts. It is grown mainly as a shade garden plant and needs cool, moist, shaded conditions with rich, humus-filled soil.
Trillium albidum is a species of flowering plant in the bunchflower family Melanthiaceae. It is the only trillium characterized by a stalkless white flower. The species is endemic to the western United States, ranging from central California through Oregon to southwestern Washington. In the San Francisco Bay Area, it is often confused with a white-flowered form of Trillium chloropetalum. In northern Oregon and southwestern Washington, it has a smaller, less conspicuous flower.
Trillium albidum was first described by John Daniel Freeman in 1975. The specific epithet albidum means "white", a reference to the uniformly white flower color of this distinctive species. It is commonly known as the giant white wakerobin or white toadshade.
Trillium albidum has the widest range of any sessile-flowered trillium in western North America, from central California through Oregon to southwestern Washington. In northern California, its range extends eastward from the Pacific coast through the Klamath Mountains into the Sierra Nevada. The type specimen was collected in Josephine County in southern Oregon. The southern edge of its range overlaps with that of T. chloropetalum in the San Francisco Bay Area. The intermediate populations found in this region may be due to hybridization of the two species.
