Stems are square, creeping, and long. Ground ivy produces nodes that root at leaf and stem axils and that can form new stolons. Flowers are blue or purple and trumpet-shaped. This weed is most common in shaded areas, but it can also grow in full sun. As with other members of the mint family, stems are square.
Flowers are violet to purple and are produced in dense clusters at the tips of branches.
Henbit is a winter annual weed that has oppositely arranged leaves with lobed margins. Flowers occur in the axils of upper leaves. Henbit is found in moist soils and can be especially troublesome in turf during early spring. Mallow is a biennial most often found in poorly maintained and underfertilized turf. Mallow produces sprawling branches that form nodes that do not root.
