The Red Fountain Grass, also known as Pennisetum setaceum, is a highly ornamental grass species native to Africa and the Middle East. It is a perennial grass that has gained popularity worldwide for its striking, red-purple foliage and vibrant, pinkish-purple flowers. This grass is widely cultivated in warm climates for its aesthetic appeal and low maintenance requirements. The Red Fountain Grass is often used as an ornamental plant in gardens, landscapes, and public spaces, adding a dramatic touch with its colorful plumes and foliage.
Characteristics and Growth Habits
The Red Fountain Grass is a clump-forming grass that can grow up to 3-5 feet (90-150 cm) tall and 2-3 feet (60-90 cm) wide. It has flat, narrow leaves that are typically 1-2 feet (30-60 cm) long and 0.5-1 inch (1.3-2.5 cm) wide. The leaves are a deep red-purple color, which provides a striking contrast to the plant’s pinkish-purple flowers. The flowers are produced on long, arching stems that give the plant a fountain-like appearance, hence its common name. The Red Fountain Grass is a warm-season grass, meaning it thrives in temperatures above 65°F (18°C) and goes dormant during the winter months.
Cultivation and Care
The Red Fountain Grass is relatively easy to care for, requiring full sun to partial shade and well-draining soil. It is drought-tolerant but performs best with regular watering. The plant can thrive in a wide range of soil types, from sandy to clay, but prefers slightly acidic to neutral soil pH. Fertilization is not necessary, but applying a balanced fertilizer during the growing season can promote healthy growth and flowering. The Red Fountain Grass is also resistant to many pests and diseases, but it can be susceptible to root rot if the soil is too moist.

Propagation and Division
The Red Fountain Grass can be propagated through division, seed, or tissue culture. Division is the most common method, as it allows gardeners to reproduce the exact same plant. To divide the Red Fountain Grass, simply dig up the entire clump, gently separate the roots, and replant the divisions in well-draining soil. Seed propagation can be more challenging, as the seeds may not produce plants with the same vibrant colors as the parent plant. Tissue culture is a more advanced method of propagation, typically used in commercial nurseries.
Pest and Disease Management
Despite its resistance to many pests and diseases, the Red Fountain Grass can still be susceptible to certain issues. Root rot can occur if the soil is too moist, while aphids, whiteflies, and spider mites can feed on the plant’s sap. Fungal diseases like powdery mildew and rust can also infect the plant, especially in humid or wet conditions. To manage these issues, gardeners can use integrated pest management techniques, such as introducing beneficial insects, practicing good sanitation, and applying targeted pesticides or fungicides.
The Red Fountain Grass has also been known to be invasive in some regions, outcompeting native vegetation and potentially harming local ecosystems. Gardeners should be aware of the potential risks and take steps to prevent the plant from spreading beyond their control.
- Use physical barriers to prevent seed dispersal
- Monitor the plant's spread and remove any escaped individuals
- Choose non-invasive alternatives for landscaping and gardening
How often should I water my Red Fountain Grass?
+The Red Fountain Grass is drought-tolerant, but it performs best with regular watering. Water the plant when the top 1-2 inches of soil feel dry to the touch, usually every 7-10 days during the growing season.
Can I grow Red Fountain Grass in containers?
+Yes, the Red Fountain Grass can be grown in containers. Choose a container that is at least 12-18 inches deep and has good drainage holes to prevent waterlogged soil. Use a well-draining potting mix and fertilize the plant regularly to promote healthy growth.
