How to grow spotted emu bush
Overview
Spotted emu bush (Eremophila maculata) is an evergreen shrub native to arid and semi-arid regions of Australia. It is grown for its attractive, tubular flowers in shades of pink, red, orange, or yellow that appear from winter to spring. This plant thrives in full sun and extremely well-drained soil, making it an excellent choice for water-wise gardens.
Varieties
- Eremophila maculata 'Aurea' — Compact shrub with bright yellow flowers; ideal for small gardens and containers in AU/NZ.
- Eremophila maculata 'Carmine Star' — Deep red-purple flowers on a bushy plant; excellent colour contrast.
- Eremophila maculata 'Pink Beauty' — Prolific soft pink blooms; hardy and easy to grow.
Soil Preparation
Prefers sandy or loamy soils with neutral to slightly acidic pH (6.0–7.5). Ensure exceptional drainage by incorporating coarse sand or gravel into clay soils. Raised beds or mounds are recommended for heavy soil areas to prevent waterlogging.
Growing Guide
Plant in a position with full sun and excellent drainage; raised beds or sandy/gravelly soil are ideal. Space shrubs 1–2 metres apart to allow for mature spread. Avoid heavy clay or poorly drained sites. Water sparingly after planting to establish a deep root system, then reduce to occasional deep watering. In humid climates, ensure air circulation to prevent fungal issues.
Sowing
Seeds require a smoke treatment or scarification to improve germination. Sow 2–3 mm deep in a sandy propagation mix, keep warm (20–25°C) and lightly moist. Germination can be erratic, taking 3–8 weeks. Direct sowing is not recommended; use pots and transplant when sturdy.
Care
Apply a low-phosphorus native fertiliser in early spring to support flowering. After the main bloom, lightly prune spent flower stems to maintain a compact shape and encourage repeat flowering. Remove any dead or diseased wood as needed; avoid heavy pruning into old wood.
Companion Planting
Pair with other drought-tolerant natives such as Grevillea 'Robyn Gordon', Westringia fruticosa, and Correa alba. Accompany with small-leaved paperbark (Melaleuca thymifolia) for contrast. Avoid heavy feeders or plants requiring constant moisture, as they will compete poorly.
Common Pests & Risks
Watch for scale insects and psyllids, which can cause leaf distortion; control with horticultural oil or systemic insecticide if severe. Root rot (Phytophthora) occurs in poorly drained soils; prevention through correct site selection is best. Snails and slugs may attack young growth in wet periods; remove by hand or use iron-based baits.
Troubleshooting
Yellow leaves: often due to overwatering or poor drainage; reduce water and improve soil permeability. Brown leaf edges: salt burn or dry winds; ensure mulch and avoid fertiliser high in nitrogen. Sparse flowering: too much shade or excess nitrogen; move to full sun and use low-phosphorus fertiliser. Sudden wilting: root rot from saturated soil; check drainage and reduce watering. White fluffy masses on stems: mealybugs; dab with alcohol or use neem oil spray.
