Horticultural Information

NCBG trait

Intro: Mat-forming annual found on roadsides and in fields, gardens, cracks in sidewalks and pavement, and other disturbed areas.

Stems: Stems branched and prostrate-spreading (mats to 2 ft. wide), dark red, hairy, leaking milky sap when broken.

Leaves: Leaves opposite, sessile, oval to oblong, to 1/2 in. long, edges minutely toothed, usually with a red splotch in the center and both surfaces sparsely hairy (denser beneath).

Inforescence:

Flowers: Flowers solitary or in small, short-stalked axillary clusters. Each "flower" is actually a cup, 1/8 in. wide, that holds male and female flowers, its rim with 4 white to pink, semi-circular, wavy-edged petal-like appendages that bear a greenish-red, thickened gland at the base; male flower anthers are yellow and nearly indistinct, and the single female flower in the cup center consists of a clump of styles sitting atop a rounded, 3-lobed ovary on a short stalk.

Fruits: Fruit a stalked, hairy, 3-lobed capsule.
