Overview

Appearance
Kochia scoparia is an annual weed that grows to 4 ft. (1.2 m) tall.
Foliage
Leaves are gray-green, alternate, entire, 0.25-2.5 in. (5-60 mm) long, up to 0.5 in. (10 mm) wide and usually covered with small hairs. The upper leaves are sometimes glabrous.
Flowers
Flowering occurs in July to October. Flowers are apetaloid, sessile, inconspicuous and occur along spikes.
Fruit
The fruits are utricles that contain one flattened, 0.1 in. (2 mm) wide seed.
Ecological Threat
Kochia scoparia is a native of Eurasia and occurs along roadsides, fields, and other disturbed places. In the winter, when the plants senesce, the plant breaks off at the base and tumbles in the wind, effectively spreading its seeds.
