The two most common types of plantain that invade landscaped areas are buckhorn plantain (P. lanceolata) and broadleaf plantain (P. major). They grow in all kinds of soils but prefer rich, moderately moist areas. The lance-shape leaves of buckhorn plantain are 4 to 12 inches long. Broadleaf plantain has oval leaves, 2 to 10 inches long. Seeds formed on the flower spikes through summer and fall remain dormant over the winter and germinate the following spring. New plants also sprout from the roots throughout the growing season. These ground-hugging, rosette-shaped plants suffocate desirable plants as they increase in size.
Plantain has fairly shallow roots and can be dug out of landscaped areas.
