Which of the following weeds is classified as a winter annual?

The correct classification for henbit as a winter annual stems from its life cycle, which completes itself within a year but specifically thrives during the cooler months. Winter annuals typically germinate in the fall or early winter, establish themselves during cooler temperatures, and then flower and produce seeds in the spring before dying off as temperatures rise.

In contrast, mouseear chickweed and yellow nutsedge are categorized differently; mouseear chickweed is often treated as a winter annual as well due to its growth pattern, but it can behave like a perennial in certain regions. Yellow nutsedge is classified as a perennial, capable of surviving across multiple growing seasons. Crabgrass is primarily a summer annual, germinating in spring and completing its life cycle before cooler temperatures arrive.

Understanding these classifications is crucial for effective weed management and the timing of herbicide applications in agricultural practices and lawn care.
