Another Name for Crepe Myrtle: Crape Myrtle and Its Aussie Garden Secrets

If you’re searching for another name for crepe myrtle, you’re likely discovering one of Australia’s favourite ornamental trees. Commonly known as crape myrtle (note the ‘a’ spelling), this beauty from the genus Lagerstroemia brings vibrant summer flowers, striking bark and reliable performance in our warmer climates. Whether you’re in subtropical Queensland or Mediterranean-like Perth, crepe myrtles thrive with minimal fuss.

In this guide, we’ll explore its names, history, top varieties for Aussie conditions and practical growing advice. Perfect for gardeners wanting low-maintenance colour that rivals natives like bottlebrush but with an exotic flair.

What’s Another Name for Crepe Myrtle?

Crepe myrtle and crape myrtle are interchangeable terms for the same plant, Lagerstroemia indica primarily, with hybrids like L. x fauriei. The name derives from the crinkled, crepe-paper-like texture of its petals, evoking fine silk fabric.

Other common names include:

• Crepe-flower tree – highlighting its floral display.
• Lilac of the South – a nod to its popularity in warm regions.
• Cape myrtle – an old misnomer from early European botanists confusing its origins.

Botanically, it’s Lagerstroemia, named after Swedish naturalist Magnus von Lagerström. In Australia, nurseries often label it simply as ‘crepe myrtle’ for familiarity, but check for Lagerstroemia indica on tags to avoid confusion with similar lythraceae family members.

A Brief History Down Under

Crepe myrtles hail from India, China and Southeast Asia, introduced to Europe in the 18th century and Australia shortly after. They exploded in popularity during the 20th century for their drought tolerance – ideal for our variable rainfall.

In Australia, they’re staples in public parks from Sydney’s Royal Botanic Garden to Brisbane streets. Unlike thirsty exotics, they suit zones 8-11 (USDA equivalent), covering most of eastern states, WA’s south-west and inland areas. Avoid frosty highlands like Tasmania’s interior where winter dieback occurs.

Why Crepe Myrtles Shine in Australian Gardens

These deciduous trees (5-10m tall, depending on variety) offer year-round appeal:

• Summer blooms: Clusters of pink, purple, red, lavender or white flowers, 2-5cm across, from December to March.
• Winter bark: Smooth, peeling cinnamon or grey trunks add sculptural interest.
• Autumn foliage: Orange-red leaves before drop.

They’re tough on water restrictions, surviving on 500-800mm annual rain once established. Soil adaptable (pH 5-7), they excel in full sun (6+ hours daily) on free-draining sites. Perfect for street plantings, screens or feature specimens.

Best Crepe Myrtle Varieties for Australian Climates

Choose compact cultivars for suburban blocks or larger for rural properties. Here are top picks:

Compact Varieties (under 4m)

• ‘Acoma’: White flowers, 3m tall x 3m wide. Suits Sydney basins, mildew-resistant.
• ‘Chickasaw’: Lavender-pink, 3.5m. Great for Perth’s dry heat.
• ‘Zuni’: Purple, 3m. Handles Brisbane humidity.

Mid-Sized (4-6m)

• ‘Natchez’: White, 6m tall x 4m. Iconic in Melbourne’s warmer suburbs, glossy bark.
• ‘Muskogee’: Light lavender, 5m. Drought-proof for Adelaide.

Larger Trees (6-10m)

• ‘Biloxi’: Pink, 7m. For Queensland’s coastal gardens.
• Indian Prince: Red flowers, 8m. Bold for rural backyards.

Seek grafted stock from reputable nurseries like NuGrow or local specialists for true-to-type performance. Native hybrids like Lagerstroemia ‘Blush’ blend Aussie resilience with colour.

Planting Crepe Myrtles in Australia

When to plant: Autumn (March-May) for root establishment before summer heat, or spring in cooler areas.

Site selection:

• Full sun, away from buildings (roots non-invasive).
• Well-drained soil; amend clay with gypsum or compost.

How to plant:

1. Dig hole 2x wider than root ball, same depth (typically 30-40cm pots).
2. Mix in slow-release fertiliser (e.g., native blend, low phosphorus).
3. Water deeply (20-30L) post-planting; mulch 5-7cm thick (sugarcane or lucerne).

Space 3-5m apart for hedges. In pots (min 50cm diameter), use premium potting mix.

Essential Care Guide

Watering

New plants need 1-2x weekly for first summer (20L each). Mature trees: deep water monthly in dry spells. Mulch conserves moisture.

Fertilising

Spring application of balanced NPK (e.g., 10-10-10) or citrus/garden fertiliser. Avoid high-nitrogen to prevent weak growth.

Pruning for Maximum Blooms

Crepe myrtles demand pruning – ignore the ‘no-prune’ myth!

• Timing: Late winter (July-August), dormant stage.
• Technique:
  • Remove suckers at base.
  • Tip-prune branches to outward buds (30-50cm back).
  • Thin crowded centres for air flow.
  • For shape: cut to 1-1.5m stubs on young trees.

This promotes floriferous new growth. Avoid ‘topping’ – it ruins form.

Pests and Diseases in Aussie Conditions

Mostly trouble-free, but watch:

• Aphids/scale: Hose off or neem oil.
• Powdery mildew: Common in humid QLD/NSW; choose resistant varieties, ensure spacing.
• White lace bugs: Underside leaf damage; pyrethrum spray.

Root rot rare in drained soils. No major diseases like myrtle rust affect them.

Propagation Tips

• Cuttings: Semi-hardwood, 10cm, summer. Root in perlite mix under mist.
• Seed: Fresh pods, but variable; stratify for germination.

Home gardeners: buy established plants for reliability.

Designing with Crepe Myrtles

Pair with:

• Grasses like lomandra for contrast.
• Salvias or agastache for pollinator buzz.
• Gravel mulch for low-water gardens.

In espalier form against walls, they create stunning vertical features.
