General Description

The large, colorful budcaps and flower clusters of this small multi-trunked tree from Western Australia make it one of the few of its tribe worth growing for its blooms. Appearing most abundantly in summer and fall but sporadically at other seasons, the cross-shaped red buds split open to reveal showy clusters of bristly lemon-yellow flowers that resemble shaving brushes. Large reddish-brown seed capsules follow the flowers. They make an interesting addition to flower arrangements. The willowy, gray green or deep green foliage contrasts beautifully with the gray or chalky white bark. Plants often have several spreading stems atop a short stout trunk. This small tree often becomes attractively gnarled with age.

This sun-loving and cold-tender plant does well in most well-drained soils. Water during dry spells to encourage maximum growth. Use it as a lawn specimen or at the back of a border.
