Plant information

Plant Description

Pennisetum ‘Rubrum’ is a charming Dwarf Purple Fountain Grass characterized by its glossy green foliage that transforms into stunning shades of yellow, amber, and bronze in late autumn. While not the hardiest of grasses, it can thrive with the aid of a protective mulch, cloche, or fleece jacket during colder periods. Ideally grown in a container, ‘Rubrum’ can be moved to a frost-free location for winter, ensuring its continued vitality and preserving its ornamental appeal. This grass variety adds a touch of elegance and seasonal beauty to gardens and landscapes.

🌿 How to Care for Pennisetum advena ‘Rubrum’ (Purple Fountain Grass)

How much sun do grasses need?

Most grasses thrive in full sun (6–8 hours daily). Some varieties can tolerate partial shade, but flowering may be reduced.

Grasses prefer well-drained soil, ideally light and moderately fertile. Heavy, waterlogged soil should be avoided to prevent root issues.

The best time to plant is spring or early autumn. Space them according to their mature size, plant at the same depth as their containers, firm in, and water well.

Water regularly during their first growing season. Once established, most grasses are drought-tolerant and only need water during prolonged dry periods.

Most grasses don’t need much feeding. In poor soils, a light compost mulch or a slow-release fertiliser in early spring is sufficient. Too much feeding can make them floppy.

Add structure, texture, and movement to your garden with hardy grasses – low-maintenance, drought-tolerant plants perfect for borders, containers, and naturalistic planting. Choose from a wide range of perennial and evergreen grasses that thrive in UK gardens. Buy quality grasses online from Middleton Nurseries today.

Divide clumps every 2–4 years to keep them healthy. The best time is early spring before new growth or late summer for warm-season types.

Many grasses are perennial, dying back in winter and returning in spring. Some types, like carex, are evergreen and stay attractive year-round.

Grasses are usually low-maintenance and pest-resistant. In overly wet or crowded conditions, issues like mildew, rust, or aphids may occasionally appear.

Common reasons include too much shade, overfeeding, or lack of division. Move to a sunnier spot, divide overgrown clumps, and avoid high-nitrogen fertiliser.
