Muhlenbergia sericea, commonly known as Sweet Grass or Muhly Grass, is a perennial grass that is deciduous or semi-evergreen depending on the climate. It is native to a variety of habitats including coastal prairies, pine barrens, and savannas in the Southeastern USA, extending to Texas and north to New Jersey. This grass typically reaches a height and width of 3-4 feet (0.9-1.2 meters), forming dense clumps of fine, blue-green foliage. In the fall, it produces airy, pink to purplish flower plumes that are highly ornamental and persist into winter, adding visual interest to the landscape.

Sweet Grass is valued for its low maintenance requirements and its striking floral display which can create a soft, cloud-like effect in gardens. It is often used in mass plantings, as an accent in borders, or in naturalized areas where its fine texture contrasts well with broader-leaved plants. Sweet Grass prefers full sun but can tolerate light shade, and while it is drought-tolerant once established, it performs best with occasional watering and well-drained soils. It is not commonly associated with serious pests or diseases, making it a resilient choice for gardeners. However, it can self-seed and spread, so it may require management in smaller spaces.CC BY-SA 4.0
