Which cool-season perennial forms rosettes with prominently veined leaves, including a species with purplish stalks?

• A. Plantain, Blackseed and Broadleaf
• B. Quackgrass
• C. Nimblewill
• D. Puncturevine

Answer: (A)

Recognizing a cool-season perennial weed that stays low in a turf stand and forms a central rosette with clearly veined leaves points you toward the plantain group. These weeds grow as a tight rosette of long, slender leaves that show bold, prominent venation across the blade. When they flower, they send up a stalk that can take on a purplish tint, which matches the clue about purplish stalks. That combination of a persistent rosette habit, conspicuous leaf veins, and a purplish flowering stalk is characteristic of plantains in turf, including broadleaf plantain and buckhorn plantain (the “plantain, blackseed and broadleaf” group). In contrast, the other options are grasses or weeds that don’t form that same rosette of veined leaves in cool-season turf, or have a different growth habit altogether.
