even grow, depending on how effectively it can migrate into newly habitable areas. Cultivation Banksia nobilis subsp. nobilis has long been a popular garden plant because of its prolific flowering. It prefers heavy, gravelly soil with excellent drainage, in a sunny position. It is drought tolerant, and frost tolerant down to -7 °C. Plants become straggly and untidy with age, so should be pruned when young. Propagation is by seed, as the hairy stems of this plant make it virtually impossible to strike stem cuttings, and heel cuttings have been met with limited success. Germination takes three to four weeks, and has an excellent success rate. Flowering usually begins at three to four years from seed. Banksia nobilis subsp. fragrans is new to cultivation and there is little information available for it. It probably requires a similar aspect to subspecies nobilis, but would be better suited to warmer areas.
