Scarlet Banksia, Waratah Banksia, Albany Banksia, Waddib

The Story

Plant Bio

Banksia coccinea, the scarlet banksia, is an erect, single-stemmed evergreen shrub native to the coastal sand dunes and shrublands of southern Western Australia. The foliage consists of stiff, wedge-shaped leaves with prominent teeth, covered in dense, velvety hairs that give the new growth a silvery-grey appearance.

The terminal flower spikes are squat, grey-budded cylinders that open to reveal vertical rows of bright scarlet styles. Because this species lacks a lignotuber, it grows as a single-stemmed specimen and cannot regenerate if cut back to bare wood.

Uses & Benefits:

Produces striking scarlet flower spikes that serve as high-value cut flowers and architectural focal points.

Acts as an effective windbreak in sandy, coastal environments where other species fail to establish.

Provides a vital source of nectar for native honeyeaters, spinebills, and small marsupials like the honey possum.

Planting

How to Grow

Select a planting site in full sun with deep, acidic to neutral sandy soil that drains instantly.
Mound the soil to a height of thirty centimetres to prevent water pooling around the collar of the plant.
Water deeply during the first summer to establish the root system, then reduce watering to rely on natural rainfall.
Apply a thick layer of coarse, organic mulch around the base, keeping it clear of the main stem to prevent rot.

Pro Tip

Plant in deep, coarse sand on a mounded bed to guarantee the rapid subsurface drainage this species requires to avoid root rot.

Care Guide

Do

Prune spent flower spikes lightly to maintain a compact shape.
Use only specialized low-phosphorus native fertilisers if nutrient deficiencies appear.
Ensure absolute subsurface drainage by planting on slopes or raised mounds.
Provide protection from heavy frosts while the plant is young.

Don't

Do not prune hard into old, leafless wood as the plant lacks a lignotuber and will die.
Do not plant in heavy clay soils or areas with high summer humidity.
Do not use standard garden fertilisers containing high levels of phosphorus.
Do not overwater once established, especially during warm summer months.
