Also called the prairie onion, this late blooming native prefers full sun with some lightly dappled shade in extreme heat. It does well in sandy or rocky soils and will thrive in shallow soil. The green, grass-like leaves, which often disappear before the 12 – 18 inch flower stalks, give off a strong scent of onion when crushed. Fall glade onion easily self-seeds, so to contain it, deadhead the pinkish-purple flowers and remove the heads from the garden. This allium is deer resistant and bees love it. It is beautiful naturalized, used in borders or in a cottage garden.
