Introducing Diamonds in the Dark Crepe Myrtle from Bunnings
If you’re hunting for a showstopper that thrives in Australian conditions, the Diamonds in the Dark crepe myrtle from Bunnings is your ticket to garden glamour. This compact Lagerstroemia indica cultivar, often simply called ‘Diamonds in the Dark’, delivers jet-black foliage that contrasts dramatically with clusters of pure white crinkly flowers in summer. It’s a modern hybrid bred for bold impact, making it ideal for small gardens, pots, or as a feature plant in larger landscapes.
Available at Bunnings in 20cm or larger pots, it’s an affordable way to add year-round interest. Priced around $20–$40 depending on size and season, it’s a smart buy for Aussie gardeners seeking low-maintenance colour. Grown in nurseries across Queensland and New South Wales, it’s propagated for reliability in our diverse climates.
Key Features of Diamonds in the Dark
- Foliage: Deep burgundy-black leaves emerge in spring, holding their dark hue through summer and autumn. They turn fiery red-orange before dropping in cooler months, providing multi-season appeal.
- Flowers: Masses of 3–4cm white blooms from December to March (southern states) or November to February (northern). Flowers sparkle against the dark leaves, living up to the ‘diamonds’ name.
- Size: Grows 2–3m tall and 1.5–2m wide, perfect for urban backyards or courtyards. It’s naturally compact, rarely needing heavy pruning.
- Bark: Smooth, peeling cinnamon-brown bark in winter adds texture when leafless.
This variety outperforms older crepe myrtles in heat tolerance and mildew resistance, thanks to its breeding from resilient parent stock.
Why It’s Perfect for Australian Gardens
Australia’s climates range from subtropical humidity in Queensland to frosty winters in Victoria and arid heat in Western Australia. Diamonds in the Dark handles it all:
- Climate Zones: Suited to USDA equivalents 8–10, or Aussie zones 3–5 in cooler areas (frost to -10°C) and up to zone 1 in the tropics. Thrives in full sun across Perth’s dry summers, Melbourne’s variable weather, and Brisbane’s humidity.
- Drought Tolerance: Once established (after 12–18 months), it copes with minimal water – ideal for water-wise gardening under restrictions.
- Soil Adaptability: Grows in sandy coastal soils, clay loams, or even poor urban dirt, as long as drainage is good.
Gardeners in Sydney report it flowering profusely even in partial shade, though full sun (6+ hours) maximises blooms. In Tasmania, it deciduous reliably, avoiding wind damage.
Planting Your Diamonds in the Dark Crepe Myrtle
When and Where to Plant
Plant in spring or autumn for best establishment. Choose a spot with full sun for maximum contrast – think north-facing borders or patios. Space 1.5–2m apart for hedges.
Soil Preparation
Crepe myrtles hate wet feet. Dig a hole twice as wide as the pot (about 50cm) and 30cm deep. Mix in:
- 30% compost or well-rotted manure for nutrients.
- Gypsum (500g per sq m) if clay-heavy to improve drainage.
- Native fertiliser granules for phosphorus-sensitive roots.
Aim for pH 5.5–7.5. In sandy Perth soils, add water-retentive mulch like lucerne straw.
Step-by-Step Planting
- Water the Bunnings pot thoroughly an hour before planting.
- Remove from pot, tease out circling roots.
- Place so top of root ball is level with ground.
- Backfill, firm gently, water deeply (20–30L).
- Mulch 5–7cm thick, keeping it away from the trunk.
For pots: Use a 40–50cm diameter container with drainage holes. Fill with premium potting mix plus slow-release fertiliser.
Care Guide for Thriving Growth
Watering
New plants need 20–30L weekly in the first summer, reducing to fortnightly once established. Deep water every 2–3 weeks in dry spells – check by poking a finger 5cm into soil; water if dry.
Fertilising
Apply a native or azalea/camellia fertiliser (low phosphorus) in early spring and late summer. Use 1 cup per sq m, watered in. For pots, every 3 months with liquid seaweed.
Pruning
Minimal needed. In winter (June–August), remove crossed branches and tip-prune for shape. Never top heavily – it ruins the natural vase form. Southern gardeners prune lightly post-flower to encourage next season’s blooms.
Mulching and Weeding
Annual 7cm mulch refresh suppresses weeds and retains moisture. Keep base weed-free to avoid competition.
Pests, Diseases and Troubleshooting
Crepe myrtles are tough, but watch for:
- Aphids/Scale: Hose off or use eco-oil spray in spring.
- Powdery Mildew: Rare in this variety; ensure good air flow and avoid overhead watering. Treat with sulphur-based fungicide if needed.
- Root Rot: From poor drainage – plant higher in clay soils.
- Yellow Leaves: Iron deficiency in alkaline soils; apply chelated iron.
In humid QLD/NSW, aphids peak in wet summers – pyrethrum is safe and effective.
| Common Issue | Cause | Fix |
|---|---|---|
| No Flowers | Too much shade/nitrogen | Full sun, balanced fertiliser |
| Leggy Growth | Insufficient light | Relocate or prune hard |
| Leaf Drop | Normal autumn or drought | Mulch and water deeply |
Design Ideas and Companions
- Borders: Plant 1.5m apart with Lomandra for evergreen base.
- Pots: Solo in large planters on balconies; underplant with Dichondra for spill.
- Hedges: 1m spacing for 1.5m screen.
- Companions: Lavender, salvias, or grasses like Dianella for texture. Pair with silver-leafed Westringia for contrast.
In modern Aussie gardens, it shines in gravel mulched beds or as a poolside accent – non-invasive roots won’t crack paving.
Where to Buy and Availability
Spot Diamonds in the Dark at Bunnings Warehouse stores nationwide, especially spring stock-ups. Check online for local stock or Click & Collect. If unavailable, similar dark varieties like ‘Black Diamond’ series are options, but this one’s foliage is unmatched.
Pro tip: Buy smaller pots for better root establishment – they catch up fast.
Propagation for Home Gardeners
Semi-hardwood cuttings in summer work well. Take 10cm stems post-flower, dip in rooting hormone, plant in sandy mix under mist. Success rate 70% with bottom heat. Seed is unreliable due to hybrids.
