Melaleuca linariifolia (Flax Leaved Paperbark) Growing Guide

What is Melaleuca linariifolia?

The closeup tree blooming flowers are borne in spikes at the ends of branches, with lovely lanceolate leaves cushioning the surrounding area. The plant can even be found in the Royal Botanic Garden and is a favourite of the Australian Native Plant Society!

Part of the Myrtaceae family, Melaleuca linariifolia is also commonly known as snow in summer or the flax-leaved paperbark. Native to eastern Australia, the species occurs mainly in coastal NSW and the surrounding swampy regions with some found as far as Western Australia and South Australia. It prefers temperate climates.

In cultivation, the plant will reach about 6 to 10 metres tall and wide but can be grown as a large tree if there's enough space. Its growing speed is considered moderate.

For smaller gardens, the Melaleuca ‘Snowstorm’ and Melaleuca ‘Sea Foam’ cultivars are excellent alternatives!

Snow in summer will also attract beneficial insects and wildlife similar to tea trees, great for gardens aiming to be more sustainable.

Caution: The roots of flax-leaved paperbark can become extensive, so try to plant it away from any waterlines and structures. The plant is also easily ignitable, so be sure to plant it away from any potential sources of fire in the garden.

Common Uses for Melaleuca linariifolia:

How to Grow Melaleuca linariifolia

For an easy and quick-to-establish route, you can find a young nursery plant in-store and online from many reputable Australian nurseries. Alternatively, this species can be reliably propagated using cuttings. Cuttings will ensure you get the desired characteristics of the parent plant whereas seeds are less reliable.

Take a healthy cutting from the current season's growth above the upper leaf axils that is at least 10cm long. Plant the cutting into a well-draining container, filled with a quality potting or propagation mix. Water well after planting then place the cutting in a warm sheltered location that gets indirect light.

Planting and Growing Conditions for Melaleuca linariifolia

• Soil - While the plant can adapt to many soil types, it does prefer sandy or heavier soils so long as the soil is well-draining.
• Sunlight - Pick a planting site that offers a sunny position. While full sun to part shade will do, more sun will ensure healthy vibrant foliage and prolific flowers.

Caring for Flax Leaved Paperbark

• Watering - Water regularly while the plant is young and developing. Once established, water occasionally but deeply when the soil is dry to the touch.
• Mulching - Apply a layer of mulch at the base of the shrub in summer to assist with soil moisture retention and to help regulate temperatures.
• Pruning - Remove dead, damaged and overgrown branches to maintain a tidy appearance. This species does tolerate regular pruning for those who wish to establish a smaller growing specimen.
• Fertilising - Apply a balanced, slow-release fertiliser from spring to summer to encourage healthy growth and flowering.

Melaleuca linariifolia Pests to Watch Out For

Melaleucas are generally healthy plants that can defend against serious pests and diseases. One pest that may become a problem is the webbing caterpillar.

Solutions: You can manually remove nests and webbing materials by cutting off affected branches. For severe infestations, you can chemically control them by using an organic neem oil spray for plants. This is best for a natural approach.
