DESCRIPTION:
Henbit is a winter annual broadleaf weed with square stems and opposite leaves. Cotyledons (seed leaves) have hairy stalks and are smooth, oval to nearly round, with a round to sharply lobed base and a truncate to slightly indented tip. The first and subsequent leaves are somewhat hairy, on hairy stalks, and are broadly oval with a lobed base, depressed veins, and rounded margin teeth. On mature plants, lower leaves are attached to leaves by short stalks are stalkless, while upper leaves are are stalkless and encircle the stem. Slender, tubular, two-lipped flowers, 1/2 to 3/4 inch (13 - 19 mm) long, are arranged in whorls between the stem and the upper leaves. Flowers have a reddish or purplish color. Plants produce triangular seeds.
