This is not the banana-like plantain that you may be thinking of. Plantago Major is a short, little herb plant. It has green, roundish oval shaped leaves. The leaf when matured is very tough and not easily broken. The very young and tender leaves can be eaten raw as salad green. The matured or older leaves are very fibrous and stringier but they can be cooked and boiled in stews. Tea made from boiling leaves in water can be used to treat various health issues. Plantago major has anti-infective, analgesic and anti-inflammatory properties and has been used widely since ancient times, to manage a wide range of diseases including constipation, coughs and wounds.
Plantain is extremely easy to grow and is tolerant of marginal and disturbed soils and once established the plants are quite hardy. Perennial, Zones 3-10.
