There are around 30 species in this Australian genus of evergreen shrubs. The leaves varyfrom long and narrow to broader and divided, and the unusual, rounded flower heads come mostly in yellow or pink and are followed by large, globe-shaped fruit cones.

Species

I. anemonifolius, drumsticks, from eastern Australia, is an upright shrub to about 2 m (6 ft) high. It produces tight, round, yellow flower heads on straight stems in spring. The light green, narrow, much-divided leaves grow to about 10 cm (4 in) long.

I. anethifolius, from New South Wales, has attractive, soft foliage which colours a bronzy brown in winter, and terminal, yellow flower heads in spring and early summer. It grows to about 1 m (3 ft).

I. dubius (Synonym: I. roseus), from Western Australia, is a small, erect, prickly shrub, to about 1 m (3 ft), with much-divided leaves and vivid pink flower heads. This species needs to be protected from frost.

I. trilobus, barrel coneflower, has unusual, divided leaves and masses of yellow flower heads.

Cultivation

In climates which are prone to regular frosts, grow in an airy intermediate greenhouse or conservatory, in pots or tubs of soil-based potting compost, enriched with grit and leaf mould. Plants need maximum light but shade from strong, direct sun. Only moderate watering is required. In the garden, grow in acid to neutral soil in a sunny, sheltered position. Propagate from seed in spring after soaking in water for a day. Germinate at 24°C (75°F).
