One form of the plant, "T. grandiflorum" f. "roseum", opens with light pink petals instead of the common white. It is generally found very rarely throughout its range but in the Blue Ridge Mountains of Virginia it can be found somewhat frequently in mixed or sometimes pure colonies. The white flowers of the common pure white variety of "T. grandiflorum" turn a very distinctive pink and remain so for several days just prior to the wilting of the flowers. Plants bearing these pink flowers are often mistaken for a "pink variety" of trillium.
