The lily leek (Allium moly) produces bright, golden-yellow flowers on 4- to 6-inch stems above lax, broad-leaved foliage. Thriving in sunny soils that dry in late summer, this species slowly increases by offsets, and occasionally by seed. Bruised foliage and flowers smell strongly of onions, which may explain why this plant is avoided by deer and rabbits. Butterflies are strongly attracted to the nectar.
