White Pampas Grass (Cortaderia selloana). Superb for fresh or dried arrangements. Silky White Feathers of Late-Summer Color. Fresh green foliage reaches 6 to 12 feet tall, topped by long, thick featherdusters of bloom that last for weeks. Unsurpassed for glorious texture and color in the landscape, this classic white Pampas Grass is the star of any garden it graces. The sturdy, fresh-green bloomstalks reach anywhere from 6 to 12 feet tall, capped by enormous snowy featherdusters. This ornamental grass blooms in late summer, just when the garden needs a little new color. Outstanding for fresh arrangements, the blooms are also wonderful if left to mature on the plant. They are also a mainstay of dried arrangements, offering superb vertical accent for any setting from a tall urn in the hallway to a wall display. This magnificent plant thrives in full sun and hot climates. Hardy in zones 6-9.
