Trillium grandiflorum, commonly known as great white trillium or wood lily, is one of the most familiar and beloved of the spring woodland wildflowers in eastern North America. Leaves, petals and sepals all come in groups of three. From an underground rhizome, a stout, unbranched, naked stem rises in spring topped by an whorl of three prominently-veined, green leaves. From the center of the leaf whorl emerges a single flower. The flowers acquire pink tones with age.

Growing and Maintenance Tips
Trilliums are easy to grow in deep, rich, humusy, moist but well-drained soils in part shade to full shade. They need regular moisture so a mulch is beneficial. They spread very gradually if left undisturbed. They go summer dormant espcially where the soil dries out. Seed is dispersed by ants.
