Wild Trillium

Forty-three species of trillium are known worldwide with a startling thirty-eight represented in North America. Within the United States, the bulk of Trillium diversity is found in the eastern states where Terrific Trilliums are among the favorites on many a spring wildflower walk. Their blooms can be either showy or obscure, a dazzling display of color on a hillside, or a chance surprise hidden under a leaf. With their eye-catching flowers, it is hard to imagine anyone not enjoying the sight of a trillium along a trail on a fine spring morning!



The decumbent trillium (Trillium decumbens) is very similar in appearance to the more common Trillium cuneatum with the exception that it seems to have no above ground “stem”. The rhizome of this species is often “s” shaped, arising from the ground several inches from where the bracts lay flat on the ground surface. Known only from a limited range in Alabama, Georgia, and Tennessee, this species often appears to have been “plucked” from its stem and laid on the ground along the side of a trail.

This trillium occurs on well-drained, rich, mesic soils in deciduous or mixed deciduous/coniferous forests.

Great white trillium occurs from southern Quebec and Ontario and then Maine west to northeastern Minnesota; through the central hardwoods to the Appalachian Mountains and thence south on the southern Appalachian Mountains to Georgia.Trillium grandiflorum has a short, thick rhizome from which a sheath (cataphyll) enclosed scape (stalk of the inflorescence) emerges from the ground to15 to 45 centimeters tall with a single, terminal flower on an erect pedicel, 2 to 10 centimeters long; leaves (actually bracts) three, dark green, sessile to sub-sessile, round-ovate to sub-rhombic, acuminate, 10 to 30 centimeters long and 8 to 15 centimeters wide; petals three, white (fading to pink) oblong, 4 to 7 centimeters long, recurved at the middle to form a very funnel-shaped corolla; sepals three, green, dark green streaked with maroon, or occasionally dark maroon, acuminate, flat, spreading, 2.5 to 5 centimeters long; fruit a berry, pale green, ovoid, six-angled, brown seeds.
