A woodland perennial with three-petalled white flowers in spring
White trillium is a perennial wildflower found in forests of eastern North America, especially in rich woods from northern Quebec to Georgia and west to Minnesota. Its large, three-petalled white blooms appear above three broad leaves in late spring. The plant often forms dense colonies and is known for its striking spring displays.

What does White trillium look like?
White trillium grows from a short underground stem called a rhizome and sends up a single stalk, usually 20–40 cm tall, topped with three broad, green leaves arranged in a whorl. Above these leaves sits a single, showy flower with three large white petals and three green sepals. The petals are often 4–7 cm long, curving outward and sometimes turning pink as they age. The flower has no scent and stands out against the forest floor, especially when many plants bloom together.
Where does White trillium come from?
This species is found in the forests of eastern North America, stretching from northern Quebec through the Appalachian Mountains to northern Georgia and west to Minnesota. Smaller, separate populations exist in places like Nova Scotia, Maine, southern Illinois, and Iowa. The plant was first described in the early 1800s and its name, grandiflorum, refers to its large flowers. White trillium is part of a group of related species and does not readily hybridize with other trilliums.
When and how White trillium blooms
White trillium blooms in late spring, usually from late April to early June, depending on location. It prefers moist, well-drained soils in mixed hardwood forests. The plant grows slowly, often taking seven to ten years to flower from seed. Seeds are spread mostly by ants, which carry them short distances, and occasionally by deer, which can move them much farther.
How White trillium is used
People admire white trillium for its springtime displays in woodlands and gardens. It is often seen carpeting forest floors in dense clusters. In some regions, it is considered a symbol or emblem, and its presence is used to gauge the health of woodland habitats. The plant is not known for use in religious or culinary traditions.
Kinds of White trillium
While most white trilliums have pure white petals, a rare form called Trillium grandiflorum f. roseum opens with salmon-pink flowers, especially in parts of Virginia. Double-flowered forms with extra petals also occur, but these are usually sterile. Some plants show unusual green markings or leaf-like floral parts, often due to disease.
What White trillium means

Large colonies, such as those in Virginia's Blue Ridge Mountains, attract visitors each year. The plant is sometimes used as a regional emblem and is monitored by ecologists as an indicator of forest health.
