Lagerstroemia Indica 'Tonto'

Crepe Myrtle ‘Tonto’

Botanical Name: Lagerstroemia indica 'Tonto'
Family: Lythraceae
Origin: East Asia
Plant Type: Deciduous tree

Overview

A compact, pink–cerise flowering crepe myrtle delivering months of colour, glowing autumn foliage and smooth, exfoliating bark. ‘Tonto’ is tailor-made for South Australian gardens: heat-tough, mildew-resistant and low-maintenance once established—ideal for feature planting, informal hedging and large pots.

Key Features

• Mature Size: 2.5-3.5 m H x 2-3 m W (upright, rounded canopy)
• Growth Rate: 30-60 cm per year under good conditions
• Foliage: Glossy green; bronze new growth; orange-red/burgundy in autumn
• Flowers: Large panicles of vivid magenta-pink blooms in summer, often continuing into early autumn
  
• Seasonal Interest: Spring flush and bronze new growth → months of magenta summer bloom → fiery autumn colour → exfoliating cinnamon-toned bark adds sculpture through winter
• Wildlife Value: Nectar-rich flowers support bees and butterflies
• Tolerance: Heat-Tolerant, Drought-Tolerant (once established), Frost Hardy (light–moderate), Wind-Tolerant (shelter while young), Coastal-Tolerant (light salt/sea breeze), Clay-Tolerant (well-drained clay loams; avoid waterlogging); naturally mildew-resistant
• Planting Density: Avenue/specimen: 1 tree per 6-12 m² (2.5-3.5 m apart), depending on mature canopy; Informal hedge/row: 1.0–1.5 m apart
• Pet Friendly: Generally regarded non-toxic to pets

Where It Works Best

• Sunlight: Full sun (6+ hrs) essential for best flowering and compact habit
• Soil: Well-drained loam, sandy loam or clay loam
• Water Needs: Establishment: 2 deep soaks/week for 8-12 weeks. Established: deep soak every 10-14 days in summer; monthly in winter if dry.
• Maintenance: Mulch in spring; light shape prune in late winter; remove spent flower clusters in summer to tidy and encourage extra bloom; balanced feed in early spring
• Lifespan: 25-50 years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Prefers slightly acidic to neutral; tolerates mildly alkaline if drainage is good

Landscape & Design Ideas

• Compact feature tree for courtyards, front gardens and pool surrounds
• Informal pink hedge/row with rhythmic summer colour and tidy structure
• Large pots for entrances and terraces; pair with silver foliage or ornamental grasses for a water-wise, modern look

Why You Will Love It
