Trillium albidum, known by the common names giant white wakerobin, white toadshade, and sweet trillium, is a species of flowering plant native to the northwestern United States from Washington to central California. It occurs in forests, woodlands, scrub, and chaparral habitat, becoming common in some areas.
Trillium albidum is a rhizomatous perennial herb with one or more erect stems growing 20 to 70 centimetres (7.9 to 27.6 in) ers in height. There is a whorl of three large leaves generally described as bracts, each measuring up to 20 centimeters in length. They are green and mottled with brownish or darker green spots. Each stem produces one flower, which is held on top of the bracts. The fragrant flower has three lance-shaped green sepals and three wider white or pink- or purple-tinged petals measuring up to 11 centimetres (4.3 in) long.
