About Plantago major L.
Scientific Name and Growth Form
Plantago major L. is a herbaceous perennial plant that grows a rosette of leaves.
Rosette Size
The rosette is typically 15–30 centimetres (6–12 inches) in diameter, and can exceptionally reach 70 centimetres (28 inches).
Leaf Shape and Dimensions
Each leaf is oval-shaped, normally 5–20 cm (2–8 in) long and 4–9 cm (1+1⁄2–3+1⁄2 in) broad, rarely growing as large as 30 cm (12 in) long and 17 cm (7 in) broad.
Leaf Apex, Margin and Petiole
Leaves have an acute apex, a smooth margin, and a distinct petiole that is almost as long as the leaf blade itself.
Leaf Venation
Five to nine conspicuous veins run the full length of each leaf.
Flower Characteristics and Inflorescence
Small greenish-brown flowers with purple stamens are produced in a dense spike 5–15 cm (2–6 in) long.
Inflorescence Stem Height
The spike sits atop a stem that is normally 13–15 cm (5–6 in) tall, and rarely reaches 70 cm (28 in) tall.
Pollination and Propagation
Plantago major is wind-pollinated, and propagates primarily by seeds that are held on the long, narrow spikes that rise well above the plant's foliage.
Seed Production and Traits
A single plant can produce up to 20,000 very small, oval-shaped seeds that have a bitter taste.
Native and Naturalized Range
The species is native to most of Europe, and northern and central Asia, but has become widely naturalized in many other regions across the world.
Habitat Preferences
It grows in lawns, fields, along roadsides, and in other areas disturbed by human activity, and grows particularly well in compacted or disturbed soils.
Introduction to North America
It is believed to be one of the first plant species to reach North America after European colonization.
Common Name Origin
It was reportedly brought to the Americas by Puritan colonizers, and some Native American peoples gave it the common name "white man's footprint", because it thrived in the disturbed and damaged ecosystems around European settlements.
Soil Rehabilitation Use
Its ability to survive frequent trampling and colonize compacted soils makes it useful for soil rehabilitation: its roots break up hardpan surfaces, while simultaneously holding soil together to prevent erosion.
Seed Dispersal Mechanism
Plantago major seeds are a common contaminant in cereal grain and other crop seeds, and this has contributed to its current worldwide distribution.
Fibre Uses
The mature plant contains pliable, tough fibres that can be used to make small cords, fishing line, sutures, or braiding in survival situations.
Ornamental Cultivars
Some cultivars are planted as ornamental plants in gardens, including 'Rubrifolia' with purple leaves, and 'Variegata' with variegated leaves.
Leaf Edibility
Young, tender leaves are edible as a salad green, but they quickly become tough and fibrous as they age.
Older Leaf Uses
Older leaves can be cooked and added to stews.
Seed Edibility
The seeds are very small, which makes them tedious to gather, but they can be ground into a flour substitute or extender.
Phytochemical Content
Plantago major contains phytochemicals including allantoin, aucubin, ursolic acid, flavonoids, and asperuloside.
Pharmacological Research
Plantain extract has been studied for its potential health effects.
Folk Medicine Leaf Uses
In folk medicine, plantain leaves were commonly used to make skin poultices for wounds, sores, or insect stings.
Folk Medicine Root Uses
The root was used to treat fever and respiratory infections.
