White trillium is a beautiful inhabitant of western Pennsylvania featuring large, pure white flowers that gracefully fade to pink by late spring. Each flower is composed of three white petals, three light green sepals that are shorter than the petals, six stamens, three stigmas, and a central white ovary.

White trillium tends to form extensive colonies that slowly spread across rich woodlands. The main pollinators of this trillium are bees and wasps, while ants are responsible for dispersing its seeds.

Frequent in moist, rich woods. Prefers shade or part shade.

Mostly found in the western half of the state.
