How to grow kangaroo paw
Overview
Kangaroo paw (Anigozanthos flavidus) is a clumping perennial shrub grown for its tall, textured flower stems and architectural foliage. It provides reliable seasonal interest and links bolder feature plants together in the garden. Key requirement: full sun and excellent drainage to avoid root rot.
Varieties
- Anigozanthos flavidus 'Landscape Gold' — Vigorous, tall golden-yellow flowers; excellent for cut flowers.
- Anigozanthos flavidus 'Bush Pearl' — Compact, pink flowers; ideal for pots and small gardens.
- Anigozanthos flavidus 'Kangaroo Paw Green' — Unusual green flowers; strong grower in temperate climates.
Soil Preparation
Kangaroo paw prefers slightly acidic to neutral soil (pH 6.0–7.0). Improve drainage by adding coarse sand, gravel, or decomposed granite. Avoid heavy clay unless raised beds are used. A light mulch of gravel or pebbles helps keep the crown dry.
Growing Guide
Plant kangaroo paw in a sunny, open position with free-draining soil. Space clumps 40–60 cm apart to allow airflow. Dig in coarse sand or gravel if soil is heavy. Water deeply but infrequently—let the soil dry out between waterings. Apply a low-phosphorus native fertiliser at planting and again in early spring.
Sowing
Sow seed in autumn or spring in warm conditions. Sow 3–5 mm deep in seed-raising mix, keep moist but not wet. Germination takes 3–6 weeks at 20–25°C. Direct sow or transplant; seedlings are slow to establish.
Care
Feed with a low-phosphorus native fertiliser in early spring and again after flowering. Cut back old flower stems and dead foliage to the base in late summer to encourage fresh growth and prevent fungal issues. Divide clumps every 3–4 years to maintain vigour.
Companion Planting
Kangaroo paw pairs well with other Australian natives like grevillea, banksia, and lomandra. Avoid planting near moisture-loving plants or in heavy shade, as this encourages fungal disease. It also attracts birds, so place near bird-friendly shrubs.
Common Pests & Risks
Ink spot (a fungal disease) causes black spots on leaves—remove affected foliage and improve airflow. Snails and slugs chew new growth; control with iron-based baits or hand-picking. Fungal issues like rust can occur in humid weather; treat with a copper-based spray.
Harvesting
Harvest flower stems when the lowest blooms on the stem begin to open. Cut at the base with sharp secateurs. Stems last 7–10 days in a vase; change water every 2 days. For dried flowers, hang upside down in a cool, dark place.
Troubleshooting
Yellow leaves: overwatering or poor drainage—reduce water and check soil. Brown leaf tips: too much fertiliser or salt buildup—flush soil with water. Stunted growth: lack of sun or phosphorus toxicity—move to full sun and use native fertiliser. Flower stems flop: heavy rain or wind—stake or plant in a sheltered spot. Black spots on leaves: ink spot fungus—remove affected leaves and improve airflow.
