Allium ampeloprasum babingtonii, also known as Babington's leek, is a cultivar of Allium ampeloprasum, a species of perennial bulbous plants in the Amaryllidaceae family. It is native to the Mediterranean region and western Asia. This cultivar is a hardy, perennial bulb, producing tall, sturdy stems up to 1m tall, with large, broad leaves and large, globular umbels of pinkish-purple flowers in late spring and early summer. The bulbs have a mild onion-like flavor, similar to leeks. It is a popular vegetable in Mediterranean cuisine, and it is used in soups, stews and as a side dish. It is also used as an ornamental plant in gardens and landscapes due to its large and showy flowers. It is tolerant of drought and can be grown in a wide range of soil types, and it is also tolerant of coastal conditions and pollution making it suitable for planting in urban areas.


Babington's Leek, scientifically known as Allium ampeloprasum babingtonii, is a unique and fascinating member of the onion family. It is a perennial plant that is native to the British Isles and is named after the 19th-century botanist Charles Cardale Babington.


Babington's Leek is a tall plant that can reach up to one meter in height. It has long, narrow, flat leaves that grow from a bulbous base, which can be up to 6 cm in diameter. The leaves are blue-green in color and can grow up to 60 cm in length. In early summer, the plant produces a tall, cylindrical flower head that can be up to 20 cm long and is composed of many small, pale pink flowers.


Babington's Leek is relatively easy to grow and is well suited to gardens and allotments. It prefers well-drained soil in full sun or partial shade and is hardy in most regions of the UK. The plant can be propagated from seed or by dividing the bulbs in the autumn or spring.

The leeks are ready for harvesting in late summer or early autumn. They are delicious when cooked and have a mild onion flavor with a slightly sweet and nutty undertone. The tender leaves can also be eaten raw in salads.


Babington's Leek is an important plant for biodiversity as it provides food and habitat for a variety of insects, including bees and butterflies. The plant is also a favorite food of the rare and endangered Allium Leaf-Mining Fly (Phytomyza gymnostoma), which is found only in the UK.


Babington's Leek is a rare and protected plant in the UK and is listed as a priority species in the UK Biodiversity Action Plan. Its natural habitat has been threatened by habitat loss and fragmentation, as well as by the spread of invasive species such as Japanese Knotweed (Fallopia japonica). Efforts are being made to conserve the species, including the establishment of conservation sites and the development of management plans to protect its habitat.

Babington's Leek is a fascinating and important plant with a rich history and cultural significance. Its delicate flavor and nutritional benefits make it a valuable addition to any garden or kitchen, while its conservation status highlights the need to protect and preserve our natural heritage.

More Information

Babington's Leek has a long history of use in traditional medicine. It was believed to have a range of therapeutic properties and was used to treat a variety of ailments, including digestive problems, coughs, and colds. The plant was also used as a poultice for wounds and insect bites.

In addition to its medicinal properties, Babington's Leek has cultural significance. It has been used in traditional Celtic and Gaelic festivals, including the Scottish festival of Beltane, where it was used to decorate May Day wreaths. The plant has also been associated with St. David, the patron saint of Wales, and is sometimes called "St. David's Leek".

Babington's Leek is closely related to the Wild Leek or Ramps (Allium tricoccum) found in North America. Both plants are popular for their flavor and culinary uses, and there is even a growing movement in North America to conserve and protect Wild Leek populations, which are also threatened by habitat loss and overharvesting.

In addition to its ecological and cultural significance, Babington's Leek has also been the subject of scientific research. Studies have shown that the plant contains a range of bioactive compounds, including flavonoids, phenolic acids, and sulfur-containing compounds, which may have antioxidant, anti-inflammatory, and antimicrobial properties.

One study found that extracts of Babington's Leek had a significant inhibitory effect on the growth of several types of bacteria, including Staphylococcus aureus, Escherichia coli, and Salmonella typhimurium. Another study suggested that the plant's flavonoids may have potential as natural remedies for inflammation-related disorders such as rheumatoid arthritis.

The bioactive compounds in Babington's Leek are not only beneficial for human health but also for the health of the environment. They have been shown to have allelopathic effects, meaning that they can inhibit the growth of other plants, including invasive species. This makes Babington's Leek a potential natural control agent for invasive species, reducing the need for synthetic herbicides and promoting a more sustainable approach to weed management.

In conclusion, Babington's Leek is a fascinating and valuable plant with a range of ecological, cultural, and medicinal benefits. Its bioactive compounds have the potential to improve human health and the health of the environment, highlighting the importance of conserving and studying this unique and significant plant.
