Melaleuca wilsonii       970

Author: Ferdinand von Müller (1825-1896)
Family: Myrtaceae Subfamily: Myrtoideae Tribe: Melaleuceae
Genus: Melaleuca
English name: Wilson's honey-myrtle
Zone: Australia

Description
It is a bushy, shrubby species from central and north-western Victoria and south-eastern South Australia, where it occurs in gravelly, sandy or clay soils and is often found in depressions. It does best in a warm to hot sunny site but also is suitable for semi-shaded locations. Best suited to semi-arid and temperate regions. Hardy to heavy frosts and withstand s extended dry periods. It is named after Charles Wilson.

Experiences
Bought at the Issa nursery, it was part of the Melaleucas tested in 2012. We know it well. It lives in the interior areas of Australia in a more arid and grassy environment and flowering profusely just like Melaleuca gibbosa.

We have them from several nurseries and we have successfully cultivated them ourselves. He is also in our cuttings program for this year to investigate possible problems with this replication technique.

Botanical Description
It is a small to medium shrub with hairy young growth. The stems are solitary or multiple. The bark is corky on older stems. There are many branches, spreading to ascending, often arching, older ones sometimes become leafless. The branchlets are glaucous.

The leaves are 0,8-1,5cm x 0,1-0,2cm, linear lanceolate, decussate, sessile, spreading to ascending, glabrous, deep green, glandular, apex pointed.

The flower-heads are in lateral clusters of 2-5 flowers., forming short to long leafless or leafy spikes, usually profuse and very conspicuous. The flowers are about 1,5cm across, pale to deep pink or purplish pink. The petals are concave, glabrous. The calyx tube is cup-shaped, glabrous.

The capsules are to about 0,5cm across, toothed rim, somewhat corky, forming a woody spike. The seeds are retained.
Useful plant
The plants can be pruned regularly and are suitable for hedging and screening as well as for general planting. The low-growing variant has pale pink flowers. Flowers attracts insects and nectar-eating birds.
