Striking and attractive Australian native plants with thick, often serrated leaves and large erect cones of stiff, wiry flowers in shades of greenish-white, yellow and orange through to red. Banksias range from ground covers, low growing shrubs to small trees and are great plants to attract bees and nectar feeding birds to the garden.
Choose a sunny spot with well drained soil. Enrich the soil with Yates Dynamic Lifter Soil Improver & Plant Fertiliser. If the soil is heavy clay based or poorly drained, add gypsum and fork in well to improve drainage and consider planting into a raised mound of well drained soil.
