The Story
Plant Bio
Gossypium sturtianum, commonly known as Sturt's Desert Rose, is an erect, woody, multi-stemmed perennial shrub native to the arid and semi-arid interior of mainland Australia. It features circular to ovate leaves containing small dark glands that release a strong scent when crushed.
The species is distinguished by its solitary, hibiscus-like mauve flowers up to 12 centimetres in diameter, which feature a contrasting dark red centre. These blooms appear throughout the year, peaking in late winter, and attract native nectar-eating birds and insects.

Planting
How to Grow
- Select a planting site in full sun with sandy, gravelly, or highly permeable loam.
- Dig a hole twice the width of the root ball but of equal depth to prevent water pooling around the stem.
- Backfill with native soil without adding organic matter or heavy fertilisers, firming gently.
- Water in lightly to settle the soil, then restrict watering to periods of extreme dry.
Pro Tip
Ensure absolute sharp drainage and restrict irrigation once established; excess water in heavy soils triggers rapid root rot.

Care Guide
Do
- Prune lightly after the late winter flowering peak to maintain a compact, bushy habit.
- Provide full solar exposure to maximise flowering and maintain foliage health.
- Ensure excellent air circulation around the canopy to prevent fungal issues in humid zones.
Don't
- Do not prune heavily into old, leafless wood as the plant struggles to recover.
- Do not overwater or plant in heavy clay soils that retain moisture.
- Do not apply heavy or high-phosphorus fertilisers, as the species is adapted to nutrient-poor soils.
