Description

Nodding Trillium is a perennial herb found from Canada south to northern Virginia and is the most northern of all the Trilliums. It has 1 or more unbranched stems that grow from underground rhizomes with a whorl of 3 bracts below the white to rarely pink 3 petaled flower. The flower is on a curving stem that often hangs below the bracts.

It is a long-lived woodland plant needing humus-rich moist soils and part to full shade. This trillium is not a good choice for the southeastern USA.

Insects, Diseases, and Other Plant Problems:  No serious problems.  Slugs and snails are occasional pests and leaf spot, rust and smut are occasional disease problems. It does not transplant well.
