Banksia integrifolia ‘Sentinel’ – Coastal Banksia (140mm Pot)
Banksia integrifolia ‘Sentinel’ is a distinctive upright selection of the Australian Coastal Banksia, valued for its narrow, columnar growth and attractive silver-backed foliage. This hardy native tree is ideal for screening, avenue planting and feature vertical accents in coastal and inland gardens.
Creamy-yellow banksia flower spikes appear from autumn through winter, providing nectar for birds and pollinators while adding seasonal interest. The foliage features glossy green upper surfaces with silvery undersides, creating movement and light contrast in the landscape.
Adapted to Australia’s east coast, Sentinel tolerates wind, salt spray, sandy soils and coastal exposure, while also performing well in general garden conditions. Naturally forming a tall, narrow tree, it is excellent for tight spaces, boundaries and modern planting schemes.
Supplied in a 140mm pot, this young coastal banksia is well established and ready to plant.
