Kochia (Kochia scoparia)

Summer annual broadleaf

Kochia
 

KochiaAn erect, much-branched summer annual weed of agronomic crops, pastures and roadsides. Seedlings have cotyledons that are narrow, essentially linear in outline, dull green in color and covered with hairs. Mature plants have leaves that occur alternately along the stem and are linear to lanceolate in outline, ranging from 1 to 2 inches in length and tapering to a point. Leaves do not occur on petioles and usually have hairs only along the leaf margins. Flowers are inconspicuous and occur in clusters at the ends of stems and in the leaf axils. Flowers have distinctive hairy bracts beneath, which tends to give the flowering stems a "prickly" appearance.
