Family: Myrtaceae
Common Name: Geraldton Wax

Only one of the 20 species of this shrubby plant from Western Australia is widely cultivated. The pretty Geraldton wax is ideal for growing on sunny banks with dry soil, or in other dry parts of the garden. It also makes a good pot plant for the cool greenhouse or conservatory. The flowers are excellent for cutting.

Species

C. uncinatum, Geraldton wax, grows to 3 m (10 ft). The leaves are slender and needle-like, and masses of lovely, waxy, white, pink or rose flowers appear in winter and spring. A number of cultivars have been produced. These include various colour forms, as well as those with extra large or tiny flowers.

Cultivation

In areas prone to frost, grow under glass in pots of lime-free, soilless potting compost and provide light, airy conditions. Outdoors, grow Geraldton wax in neutral to acid soil with good drainage. A poor or moderately fertile, sandy or gravelly soil gives good results. Plants must have a sunny position. Prune after flowering to encourage a compact shape and to avoid ugly, old wood developing. Cutting back into old hardwood may kill this shrub. Propagate from semi-ripe cuttings taken in late summer. Seed can be tried in spring under glass but germination can be difficult. Do not cover seed with compost. Germinate seed at 18°C (64°P).
