Giant Candles Banksia

Banksia ericifolia x spinulosa 'Giant Candles'

The Story

Plant Bio

The genus Banksia comprises evergreen Australian woody plants in the Proteaceae family, distinguished by their unique, nectar-rich cylindrical flower spikes. These plants are adapted to nutrient-poor soils and rely on specialized proteoid root systems to absorb phosphorus efficiently.

'Giant Candles' is a dense, multi-stemmed hybrid shrub that produces exceptionally large, vertical, bronzy-orange flower spikes measuring up to 40 centimetres in length. It features fine, needle-like dark green foliage and exhibits high tolerance to coastal winds, moderate drought, and humid subtropical climates.

Uses & Benefits:

Ornamental UsesProduces massive, vibrant bronzy-orange flower spikes that provide striking architectural interest in autumn and winter.
Practical UsesServes as an effective, dense privacy screen or windbreak that tolerates coastal exposure and moderate drought.
Ecological BenefitsProvides a vital winter nectar source for honeyeaters, wattlebirds, and native bees, while mature cones feed seed-eating birds.

Planting

How to Grow

  1. Select a planting site in full sun to light shade with highly permeable, well-drained soil.
  2. Dig a hole twice the width of the root ball and of equal depth, avoiding any soil compaction.
  3. Gently settle the plant into the hole, backfill with native soil, and water in thoroughly to eliminate air pockets.
  4. Apply a thick layer of coarse, low-phosphorus organic mulch around the base, keeping it clear of the stem.

Pro Tip

Prune lightly only after the winter flowering flush; cutting back into old, leafless brown wood will kill the branch as eastern banksias lack epicormic buds to initiate new growth.

Keep It Thriving

Care Guide

Do

  • Prune lightly after flowering to maintain a compact, bushy form.
  • Grow in highly free-draining sandy or loamy soils to prevent root rot.
  • Use only low-phosphorus native fertilisers when feeding is necessary.

Don't

  • Do not prune hard into old, bare wood as the plant will not regenerate.
  • Do not plant in heavy, waterlogged clay soils.
  • Do not apply standard high-phosphorus garden fertilisers.
