(Plantago lanceolata)
Photo Courtesy of PBI/Gordon Corp. Buckhorn plantain is a slender fibrous rooted perennial. The leaves
develop in a basal rosette. They are long slender leaves approx-
imately one inch across. The leaves have distinctive parallel
venation.
The main growth period for buckhorn plantain is from June through
September. The seed heads are cylindrical spikes found at the tip
of erect, leafless stalks which are 4 - 12 inches long. The stalks can
be hard to cut with mowers. Buckhorn plantain spreads by seeds
and shoots from the roots.
Buckhorn is found throughout the entire continental United States.

Immature Stage
Integrated Pest Management Control Recommendations
Cultural Practices:
Buckhorn plantain can be mechanically or physically removed. Care should be taken to assure that roots are
thoroughly removed. Close mowing prevents seedhead formation and helps to prevent spread. Good insect and
disease control will help to prevent the open spaces that broadleaf plantain will fill. Good fertility and proper soil
pH will help to prevent infestations. Soil testing which reveals high pH levels should be acidified, to a pH level of
6.5 to 7.
Herbicide Use:
Apply a selective broadleaf herbicide in mid-spring after seed germination in the rosette to flower stage or in the
fall when active growth has resumed.
