Fountain grass, known scientifically as Pennisetum setaceum, is a perennial grass native to Africa and the Mediterranean region. It is characterized by its arching, feathery flower spikes that can reach up to three feet in height. The grass typically grows in clumps and is often used in landscaping for its ornamental appeal. This grass thrives in warm, dry climates and is commonly found in gardens and parks. However, it can become invasive in some areas, outcompeting native plants. Fountain grass is also drought-tolerant, making it a popular choice for xeriscaping, which is a landscaping method that conserves water.
