DESCRIPTION:
Henbit is a winter annual weed with square stems and opposite leaves. Seedling leaves are small and oblong, with entire margins. The first true leaves are rounded and coarsely toothed with visible netted veins. On mature plants, lower leaves are attached to leaves by short stalks (petioles), while upper leaves are sessile (lacking a petiole) and encircle the stem. Slender, tubular, 2-lipped flowers, 1/2 to 3/4 inch (13 - 19 mm) long, are in whorls between the stem and the upper leaves. Flowers have a reddish or purplish color. Plants produce triangular seeds.
