Allium ursinum, known as wild garlic, ramsons, cowleekes, cows's leek, cowleek, buckrams, broad-leaved garlic, wood garlic, bear leek, Eurasian wild garlic or bear's garlic, is a bulbous perennial flowering plant in the amaryllis family, Amaryllidaceae. It is native to Eurasia, where it grows in moist woodland.[2] It is a wild relative of onion and garlic, all belonging to the same genus, Allium. There are two recognized subspecies: A. ursinum subsp. ursinum and A. ursinum subsp. ucrainicum.[3]
Etymology
The Latin specific name ursinum translates to 'bear' and refers to the supposed fondness of the brown bear for the bulbs; folk tales describe the bears consuming them after awakening from hibernation.[3] Another theory is that the "ursinum" may refer to Ursa Major, as A. ursinum was perhaps one of the most northerly distributed Allium species known to the ancient Greeks,[3] though this hypothesis is disputed.[4] Common names for the plant in many languages also make reference to bears.[5]
Cows love to eat them, hence the modern vernacular name of cows's leek.[6] In Devon, dairy farmers have occasionally had the milk of their herds rejected because of the garlic flavour imparted to it by the cows having grazed upon the plant.[6]
Ramsons is from the Old English word hramsa, meaning "garlic". There is evidence it has been used in British cuisine since the Celtic Britons over 1,500 years ago.[7]
Early healers among the Celts, Gaels, and Teutonic tribes and ancient Romans were familiar with the wild herb who called it herba salutaris, meaning 'healing herb'.[7]
Allium ursinum is a bulbous, perennial herbaceous monocot, that reproduces primarily by seed. The narrow bulbs are formed from a single leaf base[8] and produce bright green entire, elliptical leaves up to 25 cm (9.8 in) long x 7 cm (2.8 in) wide with a petiole up to 20 cm (7.9 in) long.[8] The inflorescence is an umbel of six to 20 white flowers, lacking the bulbils produced by some other Allium species such as Allium vineale (crow garlic) and Allium oleraceum (field garlic).[9][8][10] The flowers are star-like with six white tepals, about 16–20 mm (0.63–0.79 in) in diameter, with stamens shorter than the perianth.[8]
It flowers in the British Isles from April to June,[8] starting before deciduous trees leaf in the spring. The flower stem is triangular in cross-section and the leaves are broadly lanceolate, similar to those of the toxic lily of the valley (Convallaria majalis).[3]
Similarity to poisonous plants

Grinding the leaves between the fingers and checking for a garlic-like smell can be helpful, but if the smell remains on the hands, one can mistake a subsequent poisonous plant for a safe one.[12] When the leaves of A. ursinum and Arum maculatum first sprout, they look similar, but unfolded Arum maculatum leaves have irregular edges and many deep veins, while ramsons leaves are convex with a single main vein. The leaves of lily of the valley are in pairs, dull green, and come from a single reddish-purple stem, while the leaves of A. ursinum each have their own stem, are shiny when new, and are bright green.[13]
Distribution and habitat
It is native to Europe and Asia, where it grows in moist woodland.[2] It can be found in temperate Europe from Ireland east to the Caucasus.[citation needed] It is common in much of the lowlands of the British Isles with the exception of the far north of Scotland, Orkney and Shetland.[14] The ursinum subspecies is found in western and central Europe, while the ucrainicum subspecies is found in the east and southeast.[3]
A. ursinum covers the forest floor in early May (Riis Skov, Denmark)
It grows in deciduous woodlands with moist soils, preferring slightly acidic conditions. In the British Isles, colonies are frequently associated with bluebells (Hyacinthoides non-scripta), especially in ancient woodland. It is considered to be an ancient woodland indicator species.[15]
Ecology
As its name suggests, A. ursinum is an important food for brown bears.[16] The plant is also a favourite of wild boar.[citation needed]
A. ursinum is the primary larval host plant for a specialised hoverfly, Portevinia maculata (ramsons hoverfly).[17]
All parts of A. ursinum are edible. The leaves can be used as salad, herb,[19] boiled as a vegetable,[20] in soup, or as an ingredient for a sauce that may be a substitute for pesto in lieu of basil. Leaves are also often used to make garlic butter.[21] In Russia the stems are preserved by salting and eaten as a salad. A variety of Cornish Yarg cheese has a rind coated in wild garlic leaves.[22] The leaves can be pickled in the same way as Allium ochotense known as mountain garlic in Korea.[23] The bulbs can be used similarly to garlic cloves, and the flowers are also edible. Parts of the plant can be used for preparing Van herbed cheese, a speciality of the Van province in Turkey.[citation needed]
Popular dishes using the plant include pesto, soups, pasta, cheese, scones and Devonnaise.[citation needed]
The leaves are also used as fodder. Cows that have fed on ramsons give milk that tastes slightly of garlic, and butter made from this milk used to be very popular in 19th-century Switzerland.[citation needed]
The first evidence of the human use of A. ursinum comes from the Mesolithic settlement of Barkær (Denmark), where an impression of a leaf has been found. In the Swiss Neolithic settlement of Thayngen-Weier (Cortaillod culture), a high concentration of pollen from A. ursinum was found in the settlement layer, interpreted by some as evidence for use of the plant as fodder.[24]
Herbal remedy
Allium ursinum has been credited with many medicinal qualities and is a popular homeopathic ingredient. It is often used for treating cardiovascular, respiratory, and digestive problems, as well as for the sterilisation of wounds.[25]
Various minerals are found in much higher amounts in Allium ursinum than in clove garlic. It is sometimes called the "magnesium king" of plants because of the high levels of this mineral found in the leaves.[citation needed]
