GENERAL INFO

Coast banksia is a large shrub to small tree that features toothed, obovate leaves with silvery undersides. Additional interest is provided by its yellow, brush-like flowers that make an appearance from autumn to spring. These blooms are appealing to gardens and urban landscapes, and are also attractive to birds and bees. Its brown woody fruits are born in distinctive cone-like structures. This species has a basal burl, an adaptation for quick recovery after fire. Pruning hard to the burl can regenerate the plant.
