Reed Manna Grass

About Reed Manna Grass

Reed Manna Grass, also known as American Mannagrass, is a robust and commanding native cool-season perennial that plays a vital role in wetland ecology. Reaching impressive heights of 3 to 5 feet, it features broad, flat leaves and large, airy flower clusters that often take on a purplish tint during the summer months. Native across the northern half of North America, it is commonly found in marshes, wet meadows, and along the banks of slow-moving streams. This grass is a powerhouse for wildlife, providing essential nesting habitat for wetland birds and serving as a larval host for several species of native invertebrates. Its extensive root system makes it an excellent choice for stabilizing banks and managing drainage in wet areas. It thrives in full sun and wet to medium-wet soils, including heavy clay or peat. Whether used for large-scale restoration or as a structural element in a rain garden, Reed Manna Grass offers both functional benefits and a graceful, upright silhouette.
