Banksia marginata
Silver Banksia

Uses: For a variety of situations dependent on form. A hardy and versatile native suitable for coastal locations. Attracts native birds and insects for food source and habitat.
Forms include a dwarf variety less than 1m tall, rounded bushy forms to 4m and straggly trees to 8m.
Cultural use: Indigenous peoples soaked the flower spikes to make a sweet drink and dried cones to make implements.
Banksias can be a little difficult to prune. They do respond well to light pruning but too much can result in heavy leaf growth at the expense of flowers. Pruning too hard into old wood can result in permanent damage to the tree.
