Avon Wheatbelt and Jarrah Forest regions of the Southwest Botanic Province. Cultivation Banksia proteoides is not often cultivated. It requires an extremely well drained soil, being particularly susceptible to poor drainage. It prefers full sun and is hardy to both drought and frost once established. Propagation is by seed, but this is by no means easy. It is thought that the seed must be no older than twelve months, and even germination is erratic and slow.
