Establishment
4-8 weeksYoung transplant developing root system and initial foliage; compact growth habit beginning to form
Keep soil consistently moist but not waterlogged for first 4-6 weeks. Provide afternoon shade in hot climates. Avoid fertilizing immediately after planting.
Vegetative Growth
3-6 monthsPlant develops bushy form with dense, glossy green foliage; aromatic leaves become more prominent
Light pruning after flowering to shape and encourage branching. Maintain moderate watering. Apply balanced fertilizer monthly during growing season (spring-summer).
Bud Formation
6-8 weeksFlower buds appear along branch tips, typically in autumn; buds visible as small red structures before opening
Reduce nitrogen fertilizer; apply phosphorus-rich fertilizer to encourage blooming. Maintain regular watering. Avoid heavy pruning at this stage.
Flowering
8-16 weeksAbundant deep red, tubular flowers (1-1.5 inches long) open in succession from winter through spring; attract birds and insects
Continue regular watering but reduce frequency slightly. Do not fertilize during heavy blooming. Deadhead spent flowers to encourage extended flowering. Provide shelter from strong winds.
Dormancy/Summer Rest
3-4 monthsFlowering subsides in summer; foliage remains evergreen but growth slows; plant conserves energy
Reduce watering significantly; allow soil to dry more between waterings. Minimal fertilizing. Prune after flowering ends to shape plant and remove dead wood. Protect from extreme heat.

Fun Facts
- 🌱 The deep red color of Correa reflexa var. cardinalis is specifically adapted to attract hummingbirds and honeyeaters, which are its primary pollinators in native Australian ecosystems. The tubular flower shape perfectly fits the beaks of these specialized nectar feeders.
- 🌱 Correa reflexa is one of only a few Australian native plants that flowers predominantly in winter, providing a valuable nectar source when most other plants are dormant—a critical adaptation in Mediterranean-climate regions.
- 🌱 The plant's common name 'Correa' honors the Portuguese botanist José Francisco Correia da Serra (1751-1823), a pioneering naturalist. The foliage is highly aromatic, with fragrant oils that intensify when leaves are brushed or crushed.
