Plantago is a common weed found in lawns, meadows, and sidewalk cracks. Its common name, plantain, is a misnomer, as it is not related to the plantain (in the banana family) or the plantain lily (Hosta), though the leaves of the broadleaf variety (Plantago major) do resemble those of hosta.
Plantago grows from a fibrous taproot that produces basal rosette leaves and seed stalks from April through October. When young, all parts of the plant are tender and edible. By midsummer, the leaves toughen and require cooking to render them edible and the mature stalks are too fibrous to eat. An advantage of allowing plantago to grow in the lawn is that mowing curtails seed production, forcing the plant to continuously produce new seed stalks that are tender, nutty, and buttery when only a few inches tall.
Medicinally, plantago is a powerhouse, used as an emollient, astringent, antimicrobial, antiviral, antitoxin, diuretic, demulcent, and vulnerary. When taken internally as a tea, it lowers blood sugar and treats lung and stomach disorders. Externally, as a poultice, it treats sores, burns, stings, rashes, and insect bites.
