White asphodel grows to a height of 50–120 centimetres (20–47 in). The plain stem is supported by fleshy, thickened roots (rhizomes). The leaves, which originate from the base of the stem, are gutter-shaped and glaucous (covered by a waxy coating), about 20–22 millimetres (0.79–0.87 in) wide and 50–70 centimetres (20–28 in) long. The white hermaphroditic flowers are funnel-shaped, 4 centimetres (1.6 in) of diameter, with six elongated petals. The flowering period extends from April through June. The egg-shaped yellow-green seed capsules are usually 8–10 millimetres (0.31–0.39 in) in length.
This plant is native to the Mediterranean area. It is commonly found in meadows and heathland of central Spain, southwest France, and along the southern Alps to the western Balkans up to an altitude of 2,000 metres (6,600 ft).
