This trillium has a slender stalk with a whorl of three large, blue-green leaves. The flower, white with purple markings, is borne above the leaves on a short, arching stem. The erect, stalked flower has an inverted, pink V at the base of each white, wavy-edged petal.

The flower is followed by fruit in early fall. The fruit is a fleshy, berry-like capsule that starts off green and changes to bright red.
