About Banksia integrifolia 'Sentinel'

Banksia integrifolia 'Sentinel' is a compact upright cultivar of Coast Banksia, selected for narrow gardens and modern landscapes. The dense silvery-green foliage and bold golden cylindrical flower spikes give it the same striking look as standard Coast Banksia in a much smaller footprint, ideal for small gardens and tight planting strips.

Sentinel grows to 4-6 metres tall and just 2-3 metres wide with a naturally narrow upright form. The compact habit, salt and wind tolerance, and reliable winter-flowering display make it an excellent feature tree, informal screen, or coastal garden specimen for both residential and commercial projects.

Sentinel is highly coastal tolerant and handles salt spray, sandy soils, and exposed positions with ease. It is also drought tolerant and low maintenance once established, performing well across coastal NSW, VIC and QLD, in full sun with well-drained soil. The flower spikes provide a major nectar source for native honeyeaters, lorikeets, and pollinators through autumn and winter.

Sentinel or standard Coast Banksia? Sentinel is a compact upright cultivar reaching just 4-6m, ideal for small gardens, narrow planting strips, balcony pots, and modern landscapes. The standard Coast Banksia grows 8-15m with a broad spreading canopy, suited to larger gardens, screening, and feature use in spacious settings. Both share the same silver foliage and golden flower spikes.
