Phormium ‘Black Rage’ is a bold, architectural foliage plant known for its dramatic dark burgundy to near-black strappy leaves. Its upright to semi-weeping habit creates strong contrast in garden beds, borders, pots, and modern landscape designs, making it an excellent feature plant for adding depth, texture, and year-round colour.
Hardy and low maintenance, this evergreen New Zealand flax is ideal for customers wanting a tough ornamental plant with strong visual impact. It performs well in sunny to partly shaded positions and is especially effective in mass plantings, coastal gardens, rock gardens, containers, and mixed borders where its dark foliage contrasts beautifully against green, silver, or flowering plants.
