Trillidium undulatum (Willdenow) Floden & E.E. Schilling. Common name: Painted Trillium, Striped Wake-robin. Phenology: Late Apr-May; late Jul-Aug. Habitat: Acidic soils of ridges, slopes, and bog margins, mostly at high elevations and often associated with Rhododendron, Tsuga, Pinus, or Picea. Distribution: NB, e. QC, s. ON, and MI, south to w. NC, nw. SC, n. GA, e. TN, and ne. OH.

ID notes: The leaves are distinctly petiolate, often ca. 1 cm long, and the leaves have a blue-green cast; populations often have a large number of "monillidiums" – 1-leaved juvenile plants. Petals are white with a red blaze, or rarely more or less lacking the blaze (Patrick 1985). Trillidium undulatum occurs in more acidic sites than any species of Trillium.

Origin/Endemic status: Native
