Common name: Purpleleaf Willowherb
Botanical name: Epilobium coloratum    Family: Onagraceae (evening primrose family)

Purpleleaf Willowherb is 1-4' tall, branching occasionally. The stems are square or round, and usually pubescent where new growth occurs, becoming glabrous with age. The hairless leaves are opposite or alternate along the stems, sessile or with short petioles, and up to 5" long and ½" across. They are narrowly lanceolate in shape, and sometimes have purple veins or spots. There are 4-8 teeth per centimeter along the margin of each leaf. The 4 notched petals are white or light pink, and span about 1/3" across. At the throat of the flower, there is a prominent pistil that is often knobby at the end, which is surrounded by several stamens. These flowers bloom for about a month during late summer or early fall. The calyx tube matures into an elongated seed capsule, which splits open to release a multitude of tiny seeds with small tufts of reddish brown hair.
