Northern Sea Oats Grass

Northern Sea Oats Ornamental Grass | Nature Hills

Northern Sea Oats (Chasmanthium latifolium), also known as Spangle Grass, Wild Oats, or even Seaoats, brings graceful, shimmering texture to your garden! This elegant native ornamental grass features intricate, wheat-like "spangles" that sway in late-summer breezes and glow in the setting sun. Its bamboo-like foliage adds lush movement and structure all season long.

Highly prized by floral designers, Northern Sea Oats produces golden seed heads ideal for dried arrangements. In fall, the seed heads and foliage turn a warm copper, offering winter interest and shelter for songbirds. A warm-season grass, it thrives in USDA zones 3-8 and handles sun, heat, humidity, drought, and even wet soils with ease!
