Trillium chloropetalum
Also called Giant Trillium, Giant White Trillium, Sessile Trillium
A clump-forming woodland perennial from California with a thick underground rhizome, whorled leaves and a large single flower. It needs cool, moist, shaded conditions, much like a native woodland wildflower.
Trillium chloropetalum, also known as giant trillium, giant wakerobin, or common trillium, is a species of flowering plant in the family Melanthiaceae. It is endemic to the western U.S. state of California, being especially frequent in and around the San Francisco Bay Area.
