growing flax plants

If you’ve ever admired the striking, sword-like foliage of New Zealand’s iconic flax, you’re not alone. Growing flax plants offers both beauty and versatility for gardeners of all skill levels. Flax, or Phormium, is renowned for its architectural appeal, vibrant colours, and resilience in a range of conditions. Whether you’re looking to create a lush coastal border, establish native habitat, or add texture to your garden, flax plants are an excellent choice. Their low maintenance and year-round interest make them a standout, especially for Kiwi gardens.

Phormium tenax

5 from 2 customers

Phormium tenax, commonly known as the NZ flax or Harakeke, is a flax plant that produces erect, green, sword-like leaves. Stems rise above the foliage in summer to bear twisted-looking flowers that result in black seed pods in autumn, and the nectar produced by the flowers attracts both birds and butterflies. Harakeke grows as a clump to about 2 m tall and the same wide, performing best when planted in full sun on a well-drained site. It is a popular landscape option that is also often used to contrast with other plant colours. Mass planting on a bank not only provides an outstanding display but is also excellent for helping to stabilise the soil.

Why Grow Flax Plants?

Flax plants are native to New Zealand and thrive in the country’s diverse climates. Known for their tolerance to salt spray, wind, and drought, Phormium varieties are perfectly suited to coastal and urban settings. Growing flax plants not only provides striking foliage, but also attracts native birds with their nectar-rich flowers. They offer erosion control, shelter, and are a staple in eco-friendly landscape designs.

Best Flax Varieties for Your Garden

Choosing the right flax variety is key when planning your garden. The classic Phormium tenax is a robust species, featuring tall, upright leaves and impressive flower spikes. For smaller spaces or container gardening, Phormium 'Green Dwarf' and Phormium 'Pepe' (Dwarf Flax) are perfect choices, offering compact growth without sacrificing the dramatic look. If you prefer softer, arching leaves, Phormium cookianum provides a more relaxed form and easily mixes into mixed plantings. For a touch of colour and contemporary flair, Phormium 'Velvet Underground' stands out with deep, velvety hues.

Tips for Successfully Growing Flax Plants

Flax plants love sunny positions but will also tolerate partial shade. When planting, ensure your soil is well-draining – heavy clay can hinder growth. Flax roots are tough, but they benefit from organic matter mixed into the soil. Water young plants regularly until established, then enjoy their drought-resistant nature. Mulching helps retain moisture and discourages weeds. For city gardens, flax is prized for minimal maintenance; simply remove old leaves each year to keep plants tidy.

Flax in Landscaping and Beyond

Growing flax plants is more than a gardening trend – it’s a sustainable choice with practical benefits. Flaxes are perfect for windbreaks, hedges, and enhancing biodiversity. Their striking form complements native plantings and modern designs alike. In Māori culture, flax has long been used for weaving and crafting, making it a plant with deep heritage and contemporary appeal.
