Growth—

Banksia marginata occurs mainly in the temperate zone of southeast Australia. It is not very cold-hardy, possibly tolerating temperatures down to around -5°c, or perhaps lower if high altitude forms are selected[1, 2]. Requires a well-drained lime-free soil and a sunny position[3, 1]. Thrives in acid sandy loams[4, 1]. Prefers a pH between 6.3 and 6.5[1]. Plants are tolerant of damp soils and sea winds[2]. If this species is to be successfully cultivated, the soil should be low in nutrients, especially in nitrates and phosphates[1]. Fire-sensitive and fire resistant forms are known. The former rely solely on seed for regeneration while the latter can regenerate from both seed and from vegetative growth from a lignotuber[5]. This species hybridizes in the wild with Banksia integrifolia and Banksia conferta penicillata[1]. A good bee plant[6, 4].

Propagation

Seed - surface sow in an ericaceous compost as soon as the seed is ripe or as soon as it is obtained and do not exclude light. Seal the pot in a plastic bag until germination takes place, which can take 1 - 3 months or more at 20°c[7]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, mid summer in sand in a frame[1].
