Establishment (0-6 months)
2-3 monthsYoung transplants or rooted cuttings with fine needle-like foliage; minimal growth in first weeks
Keep soil consistently moist but not waterlogged. Provide afternoon shade in hot regions. Protect from strong winds. Avoid transplanting shock by avoiding root disturbance.
Vegetative Growth (6-18 months)
12 monthsBushy development with increasing branching; dense foliage becomes more pronounced; plant reaches 50% of mature height
Water moderately as drought tolerance increases. Light pruning to encourage bushiness; pinch back growing tips if leggy growth appears. No fertilizer needed.
Pre-flowering (18-24 months)
3-6 monthsPlant approaching mature shape; foliage thick and healthy; flower buds begin forming on branch tips
Reduce watering frequency. Light shaping pruning only. Avoid nitrogen-rich fertilizers that delay flowering.
Flowering (24+ months, spring/early summer)
6-8 weeksSmall (5mm), five-petaled white to pale pink flowers in clusters at branch tips; flowers attract bees and other pollinators
Minimal intervention. Do not fertilize during flowering. Deadheading optional (promotes tidiness but is not necessary).
Post-flowering/Seed Production (summer-autumn)
4-6 monthsFlowers fade; small capsular fruits develop containing tiny seeds; foliage remains ornamental
Allow fruits to mature if collecting seed. Very light pruning after flowering to maintain shape. Water sparingly.

Harvest Tips
Not a harvested plant in traditional sense. For ornamental use: Cut flowers for arrangements during peak bloom (spring). For seed collection: Allow capsules to dry on plant (summer-autumn), then collect and dry further indoors before storing in cool, dry place. Essential oil extraction requires specialized equipment; not practical for home gardeners.
