How to Identify Plantain

Two species dominate lawns: broadleaf plantain (Plantago major) with wide oval leaves, and buckhorn plantain (Plantago lanceolata) with narrow lance-shaped leaves. Both grow as a flat basal rosette pressed close to the ground. The defining feature on both species is the prominent parallel veins (ribs) running the length of each leaf. If you pull a leaf and the veins stretch like strings, it’s plantain.

Broadleaf plantain produces a single tall seed stalk from the center of the rosette, topped with a dense cylinder of tiny green flowers. Buckhorn plantain produces multiple thinner stalks with small oval seed heads at the tips.

Why It Grows in Your Lawn

Plantain is a compaction indicator, similar to goosegrass. It thrives in heavy, compacted soil with poor drainage. It tolerates foot traffic better than most lawn grasses, which is why it appears along walkways, in play areas, and wherever the ground gets packed down. Core aeration is as important as herbicide for long-term plantain control.

Frequently Asked Questions

Is plantain weed easy to kill?

Yes. Plantain responds to any broadleaf herbicide containing 2,4-D, dicamba, or triclopyr. It's one of the easier lawn weeds to kill with selective herbicide. The challenge is preventing it from returning, which requires fixing the compacted soil it thrives in.

Is plantain weed edible?

Yes. Broadleaf plantain leaves are edible and have been used medicinally for centuries. Young leaves can be eaten raw in salads or cooked like spinach. This is a different plant than the banana-like plantain fruit.

Why do I have plantain in my lawn?

Compacted soil. Plantain thrives where the ground is packed down from foot traffic, mower wheels, or heavy clay. Core aeration in fall relieves compaction and helps grass outcompete plantain. Without addressing compaction, the weed returns after treatment.
