About plant names...

The painted trillium is native to eastern North America. Trilliums are members of the lily family.

Identification: Plants are 4-16" (11-40 cm) high, with dark greenish or maroon stems. A whorl of three leaves forms atop each of the 1-3 stems, each leaf facing straight upward, with a single flower emerging from the center. Leaves are oval or diamond-shaped in shape, wider at the base, tapering to pointed tips, and with even edges, 4½-7" (12-18 cm) × 3-8" (8-20 cm). A flower tops each stem, elevated above the leaves, with three conspicuous white petals tinged with pink near the centers, and large yellow stamens. Each petal is about 1-1½" (2.5-3.8 cm) long and ½-¾" (1.3-1.9 cm) wide. Fruits are ⅜-¾" (1-2 cm), roughly pear-shaped or shaped somewhat like a prism, and scarlet in color.
