Yellow Trillium

Trillium luteum, commonly called yellow trillium, has beautiful mottled leaves. The flower (5 cm high) features three erect, yellow petals and three narrow, greenish sepals and appears stalkless atop the center of the three-leaf whorl. Flowers may have a faint lemon scent. It is a clump-forming plant with stems arising from thick, underground rhizomes which will spread slowly if left undisturbed. Foliage will usually die to the ground by mid-summer, particularly if the soil is allowed to dry out.
