Northern sea oats (Chasmanthium latifolium, formerly Uniola latifolia) is a 3- to 4-foot-tall, perennial grass with flattened flower- and seedheads in summer and fall. The dangling heads look terrific in fresh or dried arrangements, adding a playful touch as they nod and sway with the slightest movement.
Be warned, though: While the plants of this U.S. native grass are clump-forming, they will self-sow freely in the garden. For that reason, you might want to consider keeping northern sea oats in a meadow planting or “wild garden,” where it can seed around without being a problem, or in a tough site where daintier plants don’t thrive (in a roadside planting, for instance). Or, commit to cutting off the seedheads in mid- to late fall. Full sun to partial shade. Perennial; Zones 4 to 9.
Harvested in October 2020. At least 25 seeds.
