Which plant has rattail seed heads several inches long?

• A. Plantain, Blackseed and Broadleaf
• B. Plantain, Buckhorn
• C. Purslane, Common
• D. Quackgrass

Answer: (A)

Rattail seed heads are long, slender spikes that rise above the leaves, with many tiny seeds packed along a single, unbranched stalk. This distinctive inflorescence is a hallmark of plantain species. In turf, broadleaf plantain and blackseed plantain develop tall, cylindrical seed stalks that can reach several inches, giving that classic “rattail” look. This makes them easy to recognize in the lawn once flowering occurs. Other weeds mentioned have different flower structures: quackgrass forms a different, more branched or foxtail-like spike, while purslane stays low and produces small, rounded seed capsules rather than a tall, needle-like tail. So, the plants that clearly show rattail seed heads several inches long are the plantains, specifically the broadleaf and blackseed varieties.
