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). 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.

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 toxic lily of the valley ( Convallaria majalis). [Wikipedia]
