A bulb with flower stalks up to 50 cm tall and 3-6 linear leaves up to 50 cm long and 25 mm wide. Each flowering stem bends downwards towards the tip and bears 4-16 flowers along one side. The pendent, strongly sweetly scented flowers are violet-blue, or rarely pink or white. The perianth (petals and sepals) is tubular-bell-shaped, 14-20 mm long, with the free lobes curling up at the tips. The outer three stamens are fused to the perianth for over three quarters of their length. The anthers are cream-coloured.
