Why Seek Plants Similar to Crepe Myrtle?
Crepe myrtles (Lagerstroemia spp.) are beloved in Australian gardens for their masses of crinkly summer flowers, peeling cinnamon bark, brilliant autumn colour and compact size. They thrive in warm climates from subtropical Queensland to temperate Victoria, tolerating drought once established. However, gardeners sometimes want alternatives for better frost tolerance, native appeal, different flower colours or pest resistance.
This guide highlights eight plants similar to crepe myrtle, focusing on those suited to Australian conditions. We’ll cover growth habits, climate suitability, care tips and comparisons. All are deciduous or semi-deciduous with showy flowers and structural interest, perfect for feature planting in full sun.
1. Bottlebrush (Callistemon spp.)
Australian natives that scream ‘similar to crepe myrtle’ with their bottlebrush-like flower spikes in fiery reds, pinks and yellows from spring to summer. Unlike crepe myrtle’s flat clusters, these are cylindrical but equally eye-catching.

- Bark and Foliage: Smooth grey bark, fine blue-green leaves; some autumn colour.
Australian Climate Fit
Ideal for coastal NSW, QLD and WA. Tolerates light frost (down to -5°C) better than crepe myrtle in cooler spots. Loves sandy soils; drought-tolerant.
Care Tips
- Plant in full sun, well-drained soil (pH 5.5-7.5).
- Water weekly until established; mulch to 5cm deep.
- Prune lightly after flowering to shape.
