This cultivar is a prostrate form of B.integrifolia raised from seed at Austraflora Nurseries in 1973.

The leaves are wedge shaped with toothed margins and are from 50-70 mm long. The new growth is a bronzy green. The flower spikes are lemon yellow and 90-110 mm long by 60-70 mm inside. The flowering season is autumn and winter. Diagnosis: B. 'Roller Coaster' can be distinguished by its prostrate form.

Cultivation

This cultivar is a useful species for semi arid conditions and may also be used for beach reclamation and erosion control. It is adaptable to a wide range of soils and positions. B. 'Roller Coaster' is hardy to light frosts and is drought tolerant, though responds well to water in dry periods.
