Allium nutans has one or two bulbs up to 1.5 to 2.0 cm (5⁄8 to 3⁄4 in) in diameter. Scapes are winged and 2-angled, 30 to 60 cm (12 to 24 in) tall. Leaves are flat, tapering at both ends, 6 to 10 mm (0.24 to 0.39 in) wide at the widest spot (rarely to 15 mm or 0.59 in), about half as long as the scapes. Umbels are spherical, with many pink to pale purple flowers.[2][5][6][7]
