Dallas Blues Switchgrass is a bold native ornamental grass prized for its wide blue-gray foliage, upright vase-shaped habit, and airy pink-purple flower plumes in late summer. It adds movement, texture, and strong winter interest to New England landscapes while staying tough, low-maintenance, and adaptable. Excellent for mass plantings, mixed borders, rain gardens, and modern landscape designs.
