About plant names...

Vasey's trillium is native to the southeastern United States.

Identification: Plants have one to two round stems, and are 12-26" (30-65 cm) tall. Three leaves form a whorl atop each stem. Leaves are almost triangular in shape, sometimes wider near the base than they are long, 4-8" (10-20 cm) × 2-8" (6-20 cm) in size. While the flower appears above the leaves in many species of Trillium, these droop below, on a short petiole. Each flower is maroon (rarely yellow) in color, with three petals, 1-2½" (3-6.5 cm) × 1½-2" (4-6 cm). Each flower has a mild sweet odor. Fruits are dark reddish maroon, generally oval but sometimes with flattened sides, ⅜-½" (1-1.4 cm) × ⅜-¾" (1-2 cm).
