The Latin name Ornithogalum of the Genus, meaning "bird's milk", derives from the Greek, while the species name narbonense refers to the French town of Narbonne.

The stems are erect and the long leaves are fleshy and lance-shaped, 8–15 millimetres (0.31–0.59 in) wide. The raceme is pyramidal, with 25-75 hermaphrodite flowers. Each flower has a long bract of 1–2 centimetres (0.39–0.79 in) and six star-shaped milky white petals bearing a pale green central vein, while the buds are oval, with longitudinal green and white stripes.
