The plant Allium ursinum is known as what?
Allium ursinum, known as wild garlic, ramsons, buckrams, broad-leaved garlic, wood garlic, bear leek or bear's garlic, is a bulbous perennial flowering plant in the lily family Amaryllidaceae. It is a wild relative of onion, native to Europe and Asia, where it grows in moist woodland.
Allium ursinum is a bulbous, perennial herbaceous monocot, that reproduces primarily by seed. The narrow bulbs are formed from a single leaf base and produce bright green entire, elliptical leaves up to 25 cm long x 7 cm wide with a petiole up to 20 cm long. The inflorescence is an umbel of six to 20 white flowers only, lacking the bulbils produced by some other Allium species such as Allium vineale (crow garlic) and Allium oleraceum (field garlic). The flowers are star-like with six white tepals, about 16–20 mm in diameter, with stamens shorter than the perianth.
It flowers in the British Isles from April to June, 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 lily of the valley (Convallaria majalis).
It is native to temperate regions of Europe, from Britain east to the Caucasus. It is common in much of the lowland British Isles with the exception of the far north of Scotland, Orkney, Shetland, and the Channel Islands.
