The Story

Plant Bio

Grevillea is a diverse genus of evergreen Australian shrubs and trees in the Proteaceae family, highly adapted to nutrient-poor soils. They are characterised by their unique, petal-less flowers where the prominent, colourful styles provide the primary visual display.

'Superb' is a dense, spreading hybrid cultivar that grows to two metres high and wide, featuring deeply divided, fern-like leaves with silvery undersides. The large, cylindrical flower spikes display a blend of red, coral-pink, apricot, and yellow, appearing continuously throughout the year with a peak in late winter and spring.

Uses & Benefits:

Continuous display of large, multi-coloured flower spikes and deeply divided, fern-like foliage.

Functions as a dense, low-maintenance screening shrub with high drought tolerance once established.

Provides abundant nectar that supports native honey-eating birds, butterflies, and native bees.

How to Grow

Select a planting site in full sun to light shade with excellent drainage.
Dig a hole twice the width of the root ball but no deeper.
Backfill with native soil, ensuring the plant sits at its original soil level.
Water in thoroughly and apply a low-phosphorus mulch around the base.

Pro Tip

Plant in highly permeable, low-phosphorus soil; standard fertilisers or heavy clay will cause fatal root toxicity.
