- Description

Henbit is a cool season annual weed in the mint family introduced from Europe. The common name, Henbit, comes from the observation that chickens like it. Hummingbirds also enjoy this wild edible for the nectar. Henbit provides valuable erosion control in many cropland fields in the southern U.S. Unlike many of its relatives in the mint family, henbit does not have a strong or distinctive mint scent.
Henbit does well in full or partial sun and moist to mesic soil that is loamy and fertile. Plants become dormant during hot weather.The plant has a shallow taproot that becomes finely branched and reproduces by reseeding itself, or vegetatively by the stems rooting at the nodes. It can spread aggressively.
Henbit is easily confused with Purple Deadnettle (L. purpureum), which has petioled leaves all the way to the top leaves. The middle and upper leaves of Henbit do not have petioles. Henbit leaves are also typically smaller than those of Purple Deadnettle (L. purpureum). The lower leaves have long petioles, while the upper leaves where the flowers occur are sessile and wrap around the stems. The upper surface of the leaves has conspicuous palmate venation and is slightly hairy.
Henbit is an important early-season source of nectar and pollen for honeybees. The leaves, stem, and flowers of the plant are edible and have a slightly sweet and peppery flavor, similar to celery. The long stems, up to 2 feet long, tend to sprawl along the ground.
