Which of the following is NOT classified as a perennial plant?

Common Lambsquarters is classified as an annual plant. Unlike perennials, which live for multiple years and typically go through cycles of growth and dormancy, annual plants complete their life cycle within a single growing season. Common Lambsquarters will germinate, grow, flower, produce seeds, and die all within one year, which is the key characteristic that distinguishes it from perennial plants like Field Bindweed, Hoary Cress, and Henbit.

Field Bindweed and Hoary Cress are both perennials that can persist and grow over several growing seasons. Henbit is a winter annual but often behaves like a short-lived perennial in some climates, as it tends to reseed itself readily. Therefore, Common Lambsquarters stands out in this context as it does not have the perennial life cycle and instead fits the classification of an annual plant.
