The Story
Plant Bio
Muhlenbergia sericea, also known as Gulf Muhly or Sweetgrass, is a clump-forming, warm-season perennial grass native to the southeastern United States. It is celebrated for its fine-textured, blue-green to gray-green foliage and its airy, cloud-like flower panicles. The 'White Cloud' cultivar is distinguished by its spectacular, billowy inflorescences of ivory-white flowers that appear in late summer and fall, creating a soft, cloud-like effect. It is a more upright and slightly larger selection than the species.
