(Trillium undulatum)

Species Description
Description:
Widely considered the most beautiful of the trillium family, the Painted Trillium is a striking woodland perennial. While other trilliums are solid white or deep red, this species features a crisp white flower with a vivid, "painted" splash of hot pink or ruby-red at the center of each petal.
Habitat in the ANF
In the Allegheny National Forest, the Painted Trillium is a specialist of cool, acidic, and moist forests. Unlike the common White Trillium which prefers rich limestone soils, this species is almost always found in the company of Eastern Hemlocks, Red Spruces, and White Pines. Look for it along the shaded, mossy banks of high-elevation streams or tucked into the acidic leaf litter of the North Country Trail.
Ecology and The Ant Express
The Painted Trillium relies on a fascinating partnership called myrmecochory (seed dispersal by ants). Each seed has a fatty, nutrient-rich attachment called an elaiosome. Ants find these seeds on the forest floor, carry them back to their underground nests, and eat the fatty treat. They then discard the actual seed in their "trash chambers"—which happen to be perfectly fertilized, protected underground nurseries for the next generation of trilliums.
Identification
The "Painted" Petals: Each of the three white petals has a distinct, wavy (undulated) edge and a brilliant pink-to-red V-shape radiating from the center.
The Foliage: Like all trilliums, it has three leaves, but these are distinctly petiolate (they have short stalks connecting the leaf to the main stem). The leaves are dark green and often have a slightly bluish or bronzy tint compared to other species.
The Fruit: After blooming in late spring (May to early June), it produces a bright, shiny red berry that stands upright, looking like a small jewel atop the three leaves.
The Stature: It is generally smaller and more delicate-looking than the large-flowered Great White Trillium (Trillium grandiflorum).
