Yes, Henbit (Lamium amplexicaule) is edible. The leaves and flowers of the plant are edible and have been used in salads, soups, and teas.  However, like with any wild plant, it's important to properly identify it and avoid consuming any that have been sprayed with pesticides or grown in contaminated soil. It's also recommended to consume henbit in moderation, as large quantities may cause digestive issues.
