Pennisetum alopecuroides, commonly known as fountain grass, is a perennial grass native to Asia and Africa. It is characterized by its arching, feathery flower spikes that resemble fountains, which bloom in late summer and fall. The plant typically grows between 2 to 4 feet tall and is often used in landscaping for its ornamental value. Fountain grass thrives in well-drained soils and prefers full sun to partial shade. It is drought-tolerant once established, making it a popular choice for gardens and xeriscaping. However, in some regions, it can become invasive, outcompeting native plants and disrupting local ecosystems.
