Pennisetum Setaceum 'Rubrum' (Purple Fountain Grass)
Pennisetum Setaceum 'Rubrum' (Purple Fountain Grass)
Pennisetum setaceum 'Rubrum' (Purple Fountain Grass) is a striking ornamental grass known for its graceful, arching form and deep purple-red foliage that intensifies in colour as it matures. In late summer to autumn, it produces soft, feathery flower spikes that rise above the foliage, resembling a fountain of purple-tipped plumes. The combination of the dramatic foliage and unique flower spikes adds texture and visual interest to gardens, borders, or containers.
This hardy, low-maintenance grass thrives in full sun and well-drained soils. It is drought-tolerant once established and provides year-round appeal with its flowing, ornamental presence. Purple Fountain Grass is perfect for adding contrast, colour, and movement to any landscape, and it also attracts pollinators like butterflies. In cooler climates, it may be treated as an annual, while in warmer regions, it can be a perennial grass that grows throughout the year.
