Description

The plant produces an erect, hairy or fuzzy stem which may be red to green in color. Arranged at wide intervals along the stem are long, lance-shaped leaves, the lowermost sometimes toothed along the edges. Atop the stem is an inflorescence of several flowers in white to yellow or orange. Lower flowerheads may branch from the axils of the alternate leaves. Each tubular, flat-faced flower is 2 or 3 centimeters wide with 5 curving, light-colored petals and 5 stamens tipped with anthers which bear blue pollen. The fruit is a capsule containing sticky seeds.[3]

Uses

Some Native Americans used the roots and leaves for medicinal purposes.[4]
