- Description
-
Nodding trillium is an herbaceous perennial wildflower found in northeastern North America as far south as northern Virginia. It is a member of the trillium family (Melanthiaceae). It is the northernmost trillium and is found in rich, moist woodlands and forest edges. Several varieties and forms have been described, but these are no longer recognized as distinct from the single, widespread species. The species epithet is Latin for “nodding.”
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 Southeast.
It has one 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.
This is a species for woodland gardens.
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.
