Giant Candles Banksia

Banksia x hybrida 'Giant Candles'

The Story

Plant Bio

Banksia is a genus of evergreen Australian woody shrubs and trees characterized by dense, cylindrical flower spikes and woody fruiting cones. These plants are adapted to nutrient-poor soils, utilizing specialized proteoid root systems that are highly sensitive to phosphorus.

'Giant Candles' is a vigorous hybrid between Banksia ericifolia and Banksia spinulosa, producing massive orange flower spikes that reach up to 16 inches in length. This cultivar forms a dense, upright, multi-stemmed large shrub with narrow, dark green leaves and bronze-toned new growth.

Uses & Benefits:

Features massive, 16-inch cylindrical orange flower spikes and dense, narrow evergreen foliage with bronze new growth.

Functions as an effective, wind-tolerant privacy screen or hedge in coastal and warm-climate gardens.

Provides a rich nectar source for hummingbirds and beneficial insects during the winter and spring months.

Planting

How to Grow

Select a planting site in full sun to very light shade with highly permeable, sandy or loamy soil.
Dig a hole twice as wide as the root ball and plant at the same depth as the container soil level.
Water deeply to settle the soil, then establish a minimal watering schedule once the root system is established.
Apply a thick layer of organic mulch around the base, keeping it clear of the main stem to prevent rot.

Pro Tip

Prune only within the active green foliage immediately after flowering; cutting back into old, bare wood prevents any new growth from shooting.

Keep It Thriving

Care Guide

Do

Do plant in exceptionally well-draining soil to prevent Phytophthora root rot.
Do use a specialized low-phosphorus native plant fertilizer if feeding is necessary.
Do prune lightly after the flowering cycle to maintain a dense, compact habit.

Don't

Don't use standard general-purpose fertilizers, as high phosphorus levels will kill the plant.
Don't overwater or plant in heavy, poorly draining clay soils.
Don't cut back hard into old, leafless wood when pruning.

Does Giant Candles Banksia need full sun?

Giant Candles Banksia does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
