Coast Banksia - Banksia integrifolia

Coast Banksia Banksia integrifolia

Coast Banksia is one of Australia's most structurally commanding native trees, salt-tolerant, drought-hardy, and capable of delivering year-round presence from the moment it's installed. At advanced specimen size, it arrives as a fully resolved landscape statement requiring no apology and no patience.

Why Coast Banksia

Native resilience: Naturally adapted to coastal and exposed sites, tolerating salt spray, sandy soils, and periods of dry without compromise.
Year-round interest: Cylindrical yellow flower spikes emerge across multiple seasons, sustaining visual interest and supporting native wildlife.
Structural form: Dense, dark canopy with contrasting silver-backed foliage provides strong architectural character in both formal and naturalistic schemes.
Low maintenance demand: Once established, requires minimal intervention, a critical consideration for large-scale or high-end low-maintenance projects.
Proven performer: One of the most widely specified native trees in professional landscape practice across coastal and inland eastern Australia.

Ideal Applications

Coastal properties: Purpose-built for exposed beachfront and headland landscapes where lesser species fail to establish or perform.
Streetscape and boundary planting: Substantial canopy and upright form suit formal avenue or screen plantings at prestige residential and commercial properties.
Native and bushland compositions: Anchors large-scale native landscape schemes with credible ecological and aesthetic weight.
Erosion-prone or sandy sites: Deep root system stabilises difficult ground conditions while delivering immediate above-ground impact.

Specimen & Installation

Spacing (screening/hedge): 3–5m
Spacing (feature/avenue): 8–15m
Planting Season: Autumn to spring
Soil & Drainage: Well-drained to sandy soils; tolerates a range of soil types including slightly saline and coastal sands; drought tolerant once established; avoid heavy clay or waterlogged conditions
Establishment Care: Water regularly for the first 6–12 months to establish a deep root system, then reduce to occasional deep watering during prolonged dry spells. Avoid phosphorus-rich fertilisers, as Banksia are highly sensitive to phosphorus toxicity.
