Great white trillium (Trillium grandiflorum)
TRILL-ee-um gran-dih-FLOOR-um
Genus:  Trillium
This showy spring-blooming trillium has large white blossoms up to 3 inches long, which fade to soft pink and from cup-shaped to open and recurved. Its veined leaves are solid green, and it grows to 18 inches tall and about half as wide.
Noteworthy Characteristics:  Most trilliums are native to woodlands and scrub of North America. They make an elegant understory species planted in groups in a woodland or shady, naturalized area. Since trilliums go dormant in summer, plant them with other shade-loving perennials to share their place until they reappear the following spring. 
Care:  Grow in rich, moist, but well-drained soil with a neutral to acidic pH. Plant in part to full shade and provide an annual mulch of rich organic matter.
Propagation:  Trilliums propagate readily by division (when plants are dormant in late summer or early fall).
Problems:  Smut, rust, fungal spots, slugs, snails.
