Also known as Inland Sea Oats, this spectacular, native ornamental grass produces spectacular, flat, oat-like seed heads that hang delicately from gracefully arching, wiry stems. The seed heads start out a vibrant, fresh green in summer and transition to a rich, coppery-bronze or golden-brown in fall, creating a stunning, two-season display.\u003c\/p\u003e\n\u003cp\u003eThis is one of the few ornamental grasses that thrives in partial shade to full shade, making it absolutely perfect for woodland gardens, shadowy borders, and shaded foundation plantings where other grasses struggle. The broad, bamboo-like, bright green leaves form dense, lush clumps that provide a beautiful, lush, textural element. The wiry stems arch beautifully, and the flat seed heads create a delightful, rustling, musical sound when they sway in the breeze, adding incredible movement, texture, and sound to the garden. Beyond the garden, the unique seed heads are highly prized by floral designers for use in elegant, textural dried bouquets. Hardy in USDA Zones 3–8 and returning reliably year after year, these unique, shade-tolerant sea oats are an absolute must-have for any woodland garden, shade border, or naturalistic landscape\u003cspan style=\"font-size: 0.875rem;\"\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan style=\"color: rgb(134, 110, 60);\"\u003e\u003cstrong\u003e🌱How to Plant \u0026amp; Grow\u003c\/strong\u003e\u003c\/span\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan style=\"color: rgb(82, 144, 44);\"\u003e\u003cstrong\u003eLight Requirements:\u003c\/strong\u003e\u003c\/span\u003e  Full sun to full shade.
