Introduction to Ornamental Grasses
Ornamental grasses are valuable additions to any landscape, yet they don’t always receive the recognition they deserve. These plants add movement and interest to the garden, rustling in the breeze and producing plumes of flowers that last through winter. Not only are they visually appealing, but they also serve functional purposes such as privacy screens, borders, and even wildlife habitats. These grasses are adaptable, deer-resistant, and low-maintenance, making them an ideal choice for any garden. Whether you’re aiming to enhance a particular landscape feature or simply want to add texture and contrast, these ornamental grasses are well-regarded by Great Garden Plants horticulturists.
What Are Ornamental Grasses?
Ornamental grasses aren’t necessarily true grasses; they include a variety of perennial plants that resemble grass, such as sedges (Carex) and rushes (Juncus). The distinguishing features are remembered with the saying: “sedges have edges, rushes are round, and grasses have nodes from top to the ground”. While these plants share a similar structure and visual appeal, they have different growing conditions and tolerances. Sedges are particularly adaptable to shaded and moist conditions, making them suitable for wet-shaded sites. Rushes thrive in wet, boggy environments and are great for rain gardens. True grasses like Miscanthus, Festuca, and Calamagrostis prefer full sun and well-drained soils, producing striking flower spikes and seed heads in late summer.
Ornamental Grasses for Full Sun
These grasses thrive in sunny environments with 8+ hours of sunlight per day. They are generally heat and drought-tolerant, making them perfect for landscapes in USDA growing zones 4 through 9. Here are some top picks:
