Understanding NZ Flax Species

Two native NZ flax species form the foundation for all the stunning cultivars you’ll find in modern landscaping: Phormium tenax (harakeke) and Phormium colensoi (wharariki). Both species are renowned for their hardy strappy leaves, vibrant flower spikes that attract native birds, and adaptability to a variety of conditions. Phormium tenax, the larger of the two, can reach heights of up to 3 metres and is commonly used for shelter, weaving, and erosion control. Phormium colensoi tends to be more compact, with softer leaves, making it ideal for smaller gardens and container plantings.

Popular NZ Flax Species and Cultivars

Over the years, horticulturists have developed a dazzling array of NZ flax species cultivars, each offering unique colours and growth habits. Many modern gardens feature selections with vivid hues, such as the deep tones of Phormium 'Purple Haze' (Purple Flax Plant), the lush green-cream stripes of Phormium 'Spearmint' (Spearmint Flax), or the bright chartreuse blades of Phormium 'Moonraker' (Moonraker Flax).

Other popular choices include Phormium 'Taya' (Taya Flax), which features compact, upright foliage suitable for borders or mass planting, and Phormium 'Licorice and Lime' (Licorice and Lime Flax), a favourite for adding architectural interest to garden beds. With so many cultivars based on the two main NZ flax species, there is a form and colour to suit every design palette.

Growing and Using NZ Flax Species in Your Garden

NZ flax species are prized for their low maintenance and adaptability. Plant them in full sun for the strongest colour display, but they’ll also handle partial shade. Flaxes tolerate coastal winds, damp soils, and even drought once established, making them an excellent backbone for sustainable New Zealand gardens. Regularly removing spent flower stalks and old leaves will keep your plants looking their best year-round.

Besides their ornamental value, NZ flax species play a significant role in ecosystem health, providing nectar for tūī, bellbirds, and bees. They’re also valuable for traditional weaving, as shelterbelts, in wetland restoration projects, and for stabilising slopes.
