Growth Stages

1

Establishment

2-4 weeks

Young transplant developing root system with initial foliage growth

Water regularly but don't overwater; ensure excellent drainage. Protect from extreme heat during first few weeks. Avoid fertilizing.

2

Vegetative Growth

6-12 months

Plant establishes bushy form with increasing needle-like foliage; no flowers present

Reduce watering frequency as plant matures. Light pruning encourages bushier growth. No fertilizer needed; poor soil is acceptable.

3

Flowering

3-5 months (typically spring to early summer)

Abundant tubular flowers (pink, magenta, or coral) appear along stems; flowers attract hummingbirds and native pollinators

Maintain minimal watering. Deadheading extends bloom period but is not essential. Avoid overwatering, which reduces flowering.

4

Post-Bloom

3-6 months

Flowers fade; plant may continue vegetative growth or enter semi-dormancy depending on climate

Reduce watering further in cooler climates. Light pruning maintains shape. Very minimal fertilizer if needed.

5

Dormancy/Rest

2-4 months

In cooler zones, plant enters semi-dormant state with minimal growth; foliage persists

Water sparingly. No fertilizing. Protect from frost in zone 9b; mulch lightly if temperatures drop below 25°F (-4°C).

Companion Planting

Plan your garden →

Plant with:

Other Australian natives (Leptospermum, Westringia) Mediterranean herbs (Lavender, Rosemary) Ornamental grasses (Stipa, Triodia) Succulents (Agave, Aloe) Desert shrubs (Leucophyllum, Salvia greggii)

Avoid planting near:

Plants requiring frequent watering (Hydrangea, Ferns) Shade-loving understory plants Heavy-feeding annuals Moisture-loving perennials (Astilbe, Hosta)

Common Pests

  • Spray with water to dislodge; use insecticidal soap if infestation is severe. Avoid overwatering, which promotes whiteflies.

  • Increase air circulation; spray foliage with water. Use miticide only if heavily infested.

  • Ensure perfect drainage; avoid overwatering. Remove affected plant if root rot develops. Plant in raised beds if soil drainage is poor.

  • Prune out heavily infested branches. Spray with horticultural oil during dormant season.
