Which weed is a perennial with narrow leaves forming a dense rosette, with leaves often twist or curl?

• A. Narrowleaf plantain
• B. Wood sorrel
• C. Common yarrow
• D. White clover

Answer: (A)

A perennial weed that stays close to the ground and forms a tight cluster of long, narrow leaves at the base is narrowleaf plantain. The leaves are linear and arranged in a basal rosette, and they often twist or curl, especially as they mature or under stress. This combination of growth habit and leaf shape is distinctive for narrowleaf plantain.

Wood sorrel looks different because its leaves are trifoliate, like three small leaflets on a petiole, not a dense rosette of narrow blades. Common yarrow has finely divided, feathery leaves along a stem, not a dense basal rosette. White clover features round, three-part leaflets, not the slender, linear leaves described.
