Default OOPs...

OOPs .... That one is Deadnettle. Apparently it is different than Henbit. I know there are two different ones. Both related to mint but the leaves are differerent. First picture is deadnettle second is henbit. We get both. Deadnettle seems to grow taller.



(See also Henbit)

Purple (or red) deadnettle is a winter annual often confused with henbit (Lamuim amplexicaule). Both weeds have square stems and belong to the mint family. The leaves of purple deadnettle are triangular in shape and less deeply lobed than henbit. The upper leaves of deadnettle are red to purple in color. The leaves of purple deadnettle have petioles with the petioles of the lower leaves being longer than the upper leaves.

The flowers of purple dead nettle are light purple in color. The flowers are arranged in whorls and form in the axis of the upper leaves. Purple deadnettle spreads by seeds.
Purple deadnettle is found throughout the United States and Canada.

Henbit, a member of the mint family, is an upright winter annual that blooms in the spring. The leaves are rounded on the end with rounded toothed edges that grow opposite one another on square stems Upper leaves lack petioles. Henbit can grow from 4 to 12 inches tall on weak stems. Although an upright plant, weak stems sprouting from the bottom may lay almost horizontal.

Henbit can be confused with purple deadnettle. The leaves of purple deadnettle, however, are more pointed at the end and are slightly scalloped. The lower leaves of purple deadnettle are on long petioles, the upper leaves are on short petioles.
The flowers of henbit are purple, tubular shaped and form in the whorls of the upper leaves. Henbit spreads only by seed and is generally not a problem in dense, vigorous turfgrass sites.
Henbit is found throughout the United States.
