Biology:  Henbit (Lamium amplexicaule) is a common winter annual broadleaf weed found throughout the United States. It can often be mistaken for another closely related winter annual broadleaf, purple deadnettle.

The consequences…Read more about Winter Injury Could Cause a Reduction of Flowering on Perennial Trees and Shrubs[Read More]
