Family: Papilionaceae

A native of New Zealand, this genus of shrubs has a range of forms. Some species are prostrate, others erect; most have flattened or cylindrical green stems which perform the same functions as the leaves which autumn very quickly, leaving the twigs bare. The leaves are either simple or pinnate, the small, fragrant, pea-shaped flowers are borne in lateral sprays and the fruit is a small, leathery pod. These attractive shrubs are particularly well suited for sheltered borders.

Species

C. flagelliformis, zone 8, is a much-branched shrub, with sprays of very tiny flowers. It grows to around 2 m (6 ft).

C. odorata is a spreading species, to 2 m (6 ft) or so, with drooping branches. The fragrant, purple-veined white flowers bloom from late spring through to midsummer.

C. williamsii, zone 8, is also much branched, with large, cream or pale yellow flowers, 25 mm (1 in) long, either solitary or in sprays of two or six. It grows to 3.5 m (11 ft) or more and needs a mild, coastal climate.

Cultivation

Tender species should be grown in a cool greenhouse in areas which are prone to frosts. Outdoors, Carmichaelia does best in mild climates and will grow in many types of soil, but not clay. Plant in spring or autumn and provide protection from frost during the first winter. Prune only if it is necessary to improve the shape of the plant. Propagate from cuttings of half ripe wood. Place the cuttings in a polythene container and keep in a cool place.

Climate

Zone 9 for most species.
