Crepe Myrtle Tree Varieties: Top Choices for Australian Gardens
Crepe myrtles (Lagerstroemia spp.) are a favourite among Australian gardeners for their stunning summer blooms, attractive bark and adaptability to our diverse climates. Native to Asia but long-established here, these deciduous trees and shrubs thrive in warm regions from subtropical Queensland to temperate southern states. Theyâre drought-tolerant once established, making them ideal for water-wise gardens.
With flowers in shades of pink, purple, lavender, red and white, crepe myrtle tree varieties offer something for every spaceâfrom compact cultivars for courtyards to large specimens for park-like backyards. In this guide, weâll explore the best varieties suited to Australian conditions, focusing on size, colour, growth habits and care tips. Most are hardy in USDA zones 8-10, covering most of Australia except frosty highlands.

Planting and Care Tips for Success
Site Selection
Choose full sun. Avoid shady spots where flowering suffers. Soil pH 5.5-7.5; amend heavy clays with compost and sand.
Planting
Autumn or early spring best. Dig hole twice width of pot, same depth. Backfill, water in with seaweed solution. Stake tall varieties against wind.
Watering and Fertilising
Deep water weekly first year (about 25L per tree). Mature trees need none except drought. Fertilise spring with native slow-release (NPK 8:1:10) at 100g per metre height.
Pruning
âCrepe murderâ warning: Donât top heavilyâruins shape. Prune in winter: remove crossing branches, suckers, thin centre for air flow. Aim for vase shape.
Pests and Diseases
- Aphids/Whitefly: Hose off or neem oil.
- Powdery Mildew: Ensure airflow; fungicide if severe in wet summers.
- Root Rot: Improve drainage.
Propagation and Sourcing
Seedlings vary; buy grafted for true colour. Propagate soft tip cuttings in summer (perlite mix, under mist). Source from specialists like NuCizia Nursery (QLD) or local Bunnings for varieties.
Designing with Crepe Myrtles
- Mass planting: Alternate colours for impact.
- Espalier: Train dwarfs on walls.
- Underplant: With Lomandra or Dianella for contrast.
In Australian gardens, crepe myrtles deliver months of colour with minimal fuss. Choose based on your climate and space, and enjoy their tropical flair year-round.
