Henbit reproduces via seeds, which germinate in early spring and fall. As a member of the mint family, this plant has square stems. The mature stems are green with some taking on a purple color. They range in height from 4 inches to over a foot. The vein pattern on the upper surface of the foliage gives it a wrinkled appearance. Leaves are opposite and have rounded teeth.
The flowers are quite small, yet highly visible and purple to pink in color and most common in spring. One plant that looks similar to henbit is ground ivy. Ground ivy is a perennial though with creeping stem, and though it has square stems, it roots at each node. Henbit has a fibrous root system, which makes hand weeding difficult.
