Pennisetum setaceum 'Rubrum' (Purple Fountain Grass)

Fountain Grass

Pennisetum setaceum 'Rubrum', or purple fountain grass, is a striking ornamental grass prized for its deep burgundy foliage and graceful, arching form. It grows 1–1.2 metres tall and wide, producing soft, purplish-pink flower plumes from summer into autumn. This drought-tolerant, fast-growing grass thrives in full sun and well-drained soils. Ideal for modern landscapes, containers, or mass plantings, it adds bold colour and texture to gardens. In cooler climates, it is often treated as an annual or overwintered indoors.
