Henbit is the common name for a very common weed here in New England: Lamium amplexicaule. It has similar properties and quite a similar look to it as another common weed: purple dead nettle. However, I have noticed that henbit prefers to grow in extremely rich soil, whereas PDN can be found just about anywhere.
For myself, I will throw bits of henbit into a salad or stir fry. I also have dried some to add to teas, as it can act as an inflammation modulator in the body and help manage rheumatic pain. It’s an easy to find, easy to identify herb/weed that is chock full of vitamins. Try adding some to scrambled eggs, pesto, or an herbal butter. The flavor is not entirely bland, but not unpleasant by any means. Enjoy!
