lateritic soils covered by open woodland or dense scrub. Mean annual rainfall is , with a mean temperature range of , and up to 80 days above . Ecology Like most other Proteaceae, B. wonganensis has proteoid roots, roots with dense clusters of short lateral rootlets that form a mat in the soil just below the leaf litter. These enhance solubilisation of nutrients, thus allowing nutrient uptake in low-nutrient soils such as the phosphorus-deficient native soils of Australia. It lacks a lignotuber, so is killed by bushfire. However it is adapted to release its seed following a fire, so populations regenerate rapidly. It has been given a rating of "Priority Four - Poorly Known Taxa" on Western Australia's Department of Environment and Conservation's Declared Rare and Priority Flora List, meaning that it has been adequately surveyed, has been determined to be rare, but is apparently not threatened. Cultivation The species is little known in cultivation. Tony Cavanagh and Margaret Pieroni rate its foliage as attractive and its flowers as showy, and state that it is just as attractive as many other large shrubs in its series. The species prefer heavy soils with good drainage, and tolerates full sun or light shade. It has good tolerance for both drought and frost. Germination of seed appears to have a success rate of only about 50%; germination is rapid, often taking less than four weeks.
