This stunning wild-flower arrives in mid-spring and makes the forest floor come alive with the mixture of white and magenta.  Like in other trilliums, leaf-like bracts are arranged in whorls of three at the top of stem (scape). Each bract has a short petiole. The solitary flower rises above the leaf-like bracts on a one-inch stalk.

Grows in cool, shady forests in acidic soil.

Found in counties other than south-east, south-central and a few south-western counties.
