Knotweed and spurge are examples of which weed category?

• A. Broadleaf Summer Annual Weeds
• B. Grasses and Sedges
• C. Perennial Weeds
• D. Warm-Season Weeds

Answer: (A)

Knotweed and spurge are broadleaf plants, not grasses, so they don’t fit the grass-and-sedge category. In many Kansas weed-management contexts, they grow and seed within a single growing season and then die, which is the hallmark of a summer annual. Put together, their broad leaves and one-year life cycle point to Broadleaf Summer Annual Weeds. They aren’t categorized by warmth alone (warm-season weeds) in this framing, and while some spurge species can persist, the common field behavior that growers rely on is that these plants are annuals with broad leaves.
