Savannah Grass (Sorghastrum nutans), also known as Yellow false-sorghum, is a perennial herbaceous plant that can reach heights of up to 1.75 metres. It is distinguished by its straight, sturdy stems topped with narrow linear leaves that can measure up to 1.5 cm wide, turning golden in the fall and adding a beautiful hue to the landscape. In summer, dense, feathery flower panicles that are golden to brown emerge at the tops of the stems, creating an attractive visual display. This species prefers well-drained soils and is typically found in full sunlight, commonly inhabiting prairies, open fields, and road edges. Hardy and resilient, Savannah grass is well-suited to varying climatic conditions and contributes to ecosystem diversity.
Ecological Role
Savannah Grass plays an important role in its habitat, serving as a food source for various insects and birds. Its flower panicles attract pollinators, thus aiding in the pollination of surrounding plants. Additionally, its deep roots help stabilize the soil and prevent erosion, making this species beneficial for the restoration of disturbed habitats.
Savannah grass seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
