‘Rubrum’ (commonly known Red Fountain Grass) is a highly popular, fast-growing ornamental clump grass celebrated for its striking burgundy-red foliage and feathery, arching flower plumes. 
Whether you are looking to plant it in a patio container or weave it into a dynamic garden border, this guide covers everything you need to know to grow it successfully.
  • Appearance: Features long, strappy leaves that emerge green in spring before deepening into a rich, dark burgundy-purple. From mid-summer through autumn, it produces elegant, nodding bottlebrush flower spikes that sway beautifully in the wind.
  • Dimensions: Typically reaches a height of 90 cm to 1.5 metres (3–5 feet) and a spread of 60 to 90 cm (24–36 inches) within a single season. 
  • Hardiness: It is a half-hardy warm-season grass. It thrives in hot weather but cannot handle severe winter freezes.

To get the most vibrant colour and healthy growth out of your Pennisetum, follow these essential care steps:
  • Light: Full sun is non-negotiable. If planted in the shade, the foliage will lose its signature burgundy punch and turn a dull green.
  • Soil: It prefers medium-to-light, fertile, and excellently drained soil. It will quickly suffer from root rot if left sitting in waterlogged ground during winter.
  • Watering: Water regularly during its first growing season to establish a deep root system. Once settled, it is fairly drought-tolerant, though it appreciates a bit of routine moisture in dry spells.
  • Feeding: Keep it light. A simple layer of organic compost mulch or a slow-release fertiliser in early spring is plenty. Avoid high-nitrogen fertilisers, which make the grass floppy and weak.
