Horticultural Information

NCBG trait

Intro: Erect or ascending perennial that branches as it ages; found widely in forests, woodlands, roadsides and pastures/disturbed areas.

Stems: Stems smooth, sometimes hairy, reddish-green; leaking milky sap when broken.

Leaves: Leaves opposite, ovate to lance-shaped, to 5 in. long by 2 in. wide, smooth-green with a notably pale mid-vein and whitish coating; leaking milky sap when torn.

Inforescence:

Flowers: Flowers in loose clusters at tips of branches and in leaf axils, white to greenish-white, less than ¼ in. long, tubular-bell-shaped with 5 erect to spreading lobes with recurved, pointy tips.

Fruits: Fruit paired drooping, slender, linear, slightly curved follicles containing silky-tufted seeds.

Comments: North American native peoples used fiber from the stem of this plant for sewing, twine, nets and bowstrings; the milky sap of stem and leaves is toxic.

Height: 1-4.5 ft.
