About Your New Hibiscus tiliaceus rubra Cottonwood
Hibiscus tiliaceus 'Rubra', commonly known as Cottonwood, is a fast-growing evergreen Australian native shrub or small tree valued for its broad heart-shaped burgundy foliage, large tropical-style flowers and exceptional performance in warm coastal positions. The yellow hibiscus flowers age through orange to deep red over the course of the day, giving striking colour contrast against the rich burgundy foliage from spring through autumn.
With a mature height of 4 to 8 metres and a spread of 4 to 6 metres, this variety forms a naturally rounded canopy that can be pruned to shape or left to grow freely as an informal screen. It performs exceptionally well in coastal, subtropical and warm temperate climates, with strong tolerance of salt, wind, clay soils and occasional waterlogging.
As a fast-growing evergreen Australian native for tropical, coastal, native and wildlife gardens, in mixed native plantings, informal hedges, shade canopies and feature positions, Hibiscus tiliaceus 'Rubra' brings burgundy foliage, colour-changing tropical flowers, dense canopy shade and reliable coastal toughness through every season.
Frequently Asked Questions
About Hibiscus tiliaceus 'Rubra' Cottonwood
What is Hibiscus tiliaceus 'Rubra' Cottonwood?
Hibiscus tiliaceus 'Rubra', commonly known as Cottonwood, is a fast-growing evergreen Australian native shrub or small tree valued for its broad heart-shaped burgundy foliage and large yellow hibiscus flowers that age through orange to red. It is native to coastal northern Australia and is one of the most striking native trees for warm coastal and tropical gardens.
How big does Cottonwood grow?
Cottonwood reaches a mature size of approximately 4 to 8 metres tall and 4 to 6 metres wide, forming a naturally rounded canopy. Growth is fast at 0.5 to 1 metre per year, and the plant can be pruned to maintain a smaller size or shaped into a single-trunk small tree.
When does Cottonwood flower?
Cottonwood produces large tropical hibiscus-style flowers from spring through to autumn. Each bloom opens buttery yellow in the morning and ages through orange to deep red over the course of the day, with multiple flowers at different stages giving a constant colour-changing display against the burgundy foliage.
Is Cottonwood suitable for coastal areas?
Yes. Cottonwood is one of the best Australian native trees for direct coastal planting. It handles salt-laden winds, sandy soils and exposed seaside positions with ease, and reflects its natural habitat along the tropical and subtropical coastlines of northern Australia.
How fast does Cottonwood grow?
Cottonwood is fast-growing, putting on 0.5 to 1 metre of growth per year in suitable conditions. It is one of the quickest ways to establish a fast tropical-style screen, feature tree or native garden anchor in warm climates.
Can Cottonwood be pruned into a hedge or small tree?
Yes. Cottonwood responds well to pruning and can be maintained as an informal hedge, dense screen or shaped into a single-trunk small feature tree. For hedging, trim two to three times per year through the growing season. For tree form, remove lower branches progressively through establishment.
Is Cottonwood frost tolerant?
No. Hibiscus tiliaceus 'Rubra' is frost sensitive and best grown in frost-free or protected positions. It performs reliably across tropical Queensland, coastal NSW and warm coastal Victoria, but should be avoided in heavily frost-prone inland areas.
Does Cottonwood attract wildlife?
Yes. The nectar-rich hibiscus flowers attract bees, butterflies, native birds including honeyeaters, and beneficial pollinators throughout the long flowering season. The dense broad canopy also offers shelter and nesting habitat for small birds, making Cottonwood one of the most valuable Australian natives for wildlife-friendly gardens.
