Red Fountain Grass
Red Fountain Grass (Pennisetum setaceum 'Rubrum')
Common Names: Red Fountain Grass, Purple Fountain Grass, Tender Fountain Grass.
Best Growing Environment: Red Fountain Grass is best planted in well-draining soil. It’s adaptable to various soil types but thrives in a loamy mix. This ornamental grass is tolerant of urban pollution, making it a popular choice for city landscaping projects.
Average Height: The grass itself can reach heights of 3 to 5 feet, with its flower plumes extending even taller, often reaching 6 feet.
Growth Rate: Red Fountain Grass boasts a moderate to fast growth rate, filling in spaces quickly during the growing season.
Sun Requirements: This grass thrives in full sun. While it can manage in partial shade, its rich colors are most vibrant when exposed to ample sunlight.
Cold Hardiness: Red Fountain Grass is a tender perennial. It's hardy in USDA zones 9-11. In cooler climates, it is often grown as an annual or overwintered indoors.
Water Requirements: While the grass is drought-tolerant once established, it does best with regular watering, especially in the heat of summer. It’s vital to ensure it doesn't sit in waterlogged soil, as this can lead to root rot.
Fertilizing Guide: Apply a balanced, slow-release fertilizer in the spring as new growth emerges. If the grass is being grown as an annual, a mid-summer feeding can also be beneficial. Over-fertilizing can lead to fewer flowers and a less compact shape, so moderation is key.
Planting Guide: Plant Red Fountain Grass in a location with full sun and well-draining soil. When planting multiple specimens, space them 3 to 4 feet apart to allow for mature growth. For container planting, ensure the pot has ample drainage holes.
USDA Zone: As previously mentioned, Red Fountain Grass is hardy in USDA zones 9-11. However, in zones colder than 9, it can be grown as an annual or brought indoors to overwinter.
With its stunning burgundy-red foliage and feathery plumes, Red Fountain Grass adds texture, movement, and color to the landscape. Its versatility allows it to be a beautiful focal point in gardens, mixed borders, or even as a container plant. Additionally, its resilience in various conditions and low maintenance requirements make it a favorite among both novice and experienced gardeners.
