Family: Rhamnaceae

Native to Australia and New Zealand, this genus comprises around 45 species of evergreen shrubs. Only a few of the species are in cultivation, though these shrubs have good horticultural potential and are impressive when in flower, in late spring and summer. They have hairy, alternate leaves and rounded fragrant flower heads, mostly in yellow, cream or white, and are interesting foliage plants and ornamentals.

Species

Not all available outside countries of origin but P. apetala is grown in California.

P. andromedifolia grows 1-3 m (3-10 ft) high. The leaves are dark green above and velvety brown underneath. The cream flowers are borne in dense clusters.

P. apetala, tainui or native hazel, occurs in New Zealand and Australia and is grown mainly for its soft and hairy foliage. It reaches around 5 m (16 ft). In spring, it is covered in long clusters of yellow flowers.

P. ferruginea, rusty pomaderris, grows to 2 m (6 ft), and has oval leaves and rich yellow flowers.

P. kumeraho, golden tainui, is a native shrub of New Zealand which grows to 3 m (10 ft). In spring, its slender branches are covered in blueish green foliage and masses of tiny, yellow flowers, in large clusters. This species was used by the Maoris in the treatment of asthma and other bronchial problems.

P. lanigera grows to 2 m (6 ft), with rusty green leaves and rounded clusters of yellow flowers.

P. pilifera is a spreading shrub, growing to 1.5 m (5 ft) in height. The green leaves are striped with white at the midrib and masses of bright yellow flowers appear in irregular clusters during spring.

P. ragosa grows to 3 m (10 ft), with rusty green leaves and white flowers.

Cultivation

Pomaderris an be propagated from the seed, contained in the fruit, which will germinate readily if sown in sand. It can also be propagated from semi-hardwood cuttings taken from late spring to autumn. These are easy-care plants which will thrive in most situations in the garden, provided there is good drainage and shelter from strong winds. Trimming is necessary only to maintain a compact shape. In frost-prone climates, grow in a cool, airy green-house or conservatory in pots of soil-based potting compost. Provide bright light.
