About Your New Banksia integrifolia ‘Birdsong’ – Birdsong Banksia

Banksia integrifolia 'Birdsong' is a compact selection of the coast banksia, chosen for dense growth and a long flowering season. Leaves are dark green above with a silver underside that flashes in the wind, and the plant holds a naturally rounded shape. Lemon-yellow flower spikes appear through autumn and winter.

Expect around 2 to 3 metres tall and 1.5 to 2 metres wide, with growth of 30 to 60 centimetres a year. Full sun and well drained soil give the best result, and it handles salt-laden coastal wind, sandy ground and light to moderate frost. Once established it copes with dry periods without supplementary water.

It is used for low screening at 1 to 1.5 metres apart, native gardens, mass planting on civic sites and street verges, and larger containers. The compact habit means it can go where the full-sized coast banksia would be too big. Landscape architects specify it where native character and bird habitat are required in a tight space.

Frequently Asked Questions

About Birdsong Banksia

What is Banksia 'Birdsong'?

Banksia integrifolia 'Birdsong' is a compact cultivar of the coast banksia, an Australian native in the family Proteaceae. It was selected for its dense rounded habit and extended flowering rather than for size. The leaves are dark green with silvery undersides, and the upright flower spikes are lemon to golden yellow.

How big does Birdsong Banksia grow?

It settles at roughly 2 to 3 metres tall and 1.5 to 2 metres wide, well short of the 15 metres the wild coast banksia can reach. That compact size is the reason it is specified for verges, courtyards and low screens. Light pruning keeps it lower again if needed.

How fast does it grow?

Growth runs at about 30 to 60 centimetres a year in reasonable conditions, so a screen closes over within two or three seasons from advanced stock. It grows fastest in sandy free draining soil with full sun. Heavy clay slows it markedly and increases the risk of root problems in wet winters.

When does Birdsong Banksia flower?

Flowering runs through autumn and winter, roughly March to August, with pale yellow spikes opening over an extended period rather than all at once. Established plants often carry a few flowers outside that window as well. The winter nectar is a significant food source for honeyeaters and small nectar-feeding birds.

Is Birdsong Banksia frost tolerant?

Once established it handles light to moderate frost without damage, so it works in most coastal and inland temperate districts. Plants in their first winter are more exposed and benefit from shelter or a light cover on the coldest nights. Severe or prolonged frost is beyond what a coastal species like this is built for.

Can Birdsong Banksia be grown in pots?

Yes, given a large container of at least 50 centimetres and a free draining native potting mix. Keep it in full sun and water when the top of the mix dries out. Use only low phosphorus native fertiliser. Repot or root prune every few years, and expect a smaller plant than one grown in the ground.

How do I care for Birdsong Banksia?

Water through the first summer, then only in long dry spells. Tip prune after flowering to keep the growth dense, cutting into leafy wood rather than bare stems. Use a native fertiliser with no phosphorus, applied lightly in spring. Mulch the root zone, keeping mulch clear of the stem, and avoid disturbing the surface roots.
