Common chickweed description includes winter annual habit and star-shaped flowers; growth habit?

• A. Winter annual; star-shaped flowers; trailing growth habit
• B. Winter annual; star-shaped flowers; upright growth habit
• C. Winter annual; star-shaped flowers; climbing growth habit
• D. Summer annual; star-shaped flowers; trailing growth habit

Answer: (A)

Common chickweed is a winter annual that germinates in fall and stays low, spreading across the ground to form mats. It has small star-shaped flowers, giving that characteristic star-like appearance. The growth habit matches a creeping, trailing form: slender stems run along the soil and root at the nodes, producing dense patches rather than standing upright or climbing. Because it overwinters as a low-growing plant and flowers in late winter to spring, the winter annual with trailing growth best describes this weed. A summer annual or an upright/climbing habit wouldn’t fit, and a trailing, mat-forming habit is a key feature of chickweed.
