Fast-growing evergreen tree producing clouds of scented, yellow pompon clusters from January to April among feathery glaucous leaves. Only half hardy so may need protection in colder parts of the country and not suitable for growing outdoors in northern England. Can reach 15m in its native Australia but usually only about 10m x 4m in Britain.

H x S: 15 m x 6m

Aspect and soil: best in full sun in moderately fertile, neutral to acid, well-drained soil, preferably in a sheltered spot.

Use: as part of a Mediterranean or antipodean-themed garden, with Eucalyptus, Callistemon (Bottle-brush bush) and Leptospermum (Tea tree).

Cultivation: cut off suckers and trim unsightly branches. Lightly prune after flowering if necessary. Casts a lot of shade so not much will grown immediately underneath unless the crown is raised sufficiently (man-height).

Wildlife: loved by insects at a time of year when not much else is in bloom.

Hazard: —

Hardiness: H3
