📌 Product Description
Phormium tenax ‘Rubra’ is a bold evergreen ornamental foliage plant grown for its long, arching, sword-like leaves in deep shades of burgundy, bronze, and reddish-purple. Its rich colouring and strong upright habit make it an excellent architectural plant for adding year-round drama, texture, and contrast to the garden.
This striking tenax variety forms a large, dense clump and works beautifully in mixed borders, feature containers, modern landscapes, and coastal gardens. It combines especially well with grasses, succulents, silver foliage plants, and flowering perennials. Its hardy, wind-tolerant nature makes it a reliable choice for many South African garden settings.
Low maintenance and visually dramatic, Phormium tenax ‘Rubra’ is ideal for gardeners wanting a strong structural plant with bold foliage colour throughout the year.
