Seedling
4-6 weeksTiny seedlings with narrow cotyledons emerge; very delicate with minimal foliage
Keep soil moist but not waterlogged; provide bright light; protect from frost; avoid damping off by ensuring good air circulation
Young growth
6-12 monthsPlant develops its characteristic narrow, needle-like leaves and begins to form a shrubby shape
Reduce watering frequency; avoid over-fertilizing; provide full sun exposure; stake if needed for wind protection
Establishment
6-12 monthsShrub becomes woody and develops a dense branching structure; root system deepens significantly
Minimal watering once drought tolerance develops; can withstand wind and poor soils; light pruning to shape if desired
Flowering
3-4 months (typically spring/early summer in Southern Hemisphere; late spring/summer in Northern Hemisphere)Plant produces abundant small, delicate white or pale pink flowers clustered along branches; highly attractive to bees
Do not prune during flowering to maximize bloom; allow nectar production for honey bees; no deadheading required
Mature shrub
3+ years and beyondFully established plant 3-6 meters tall with dense foliage and consistent annual flowering and seed production
Minimal maintenance required; tolerates poor soils and drought; can be pruned for shape or as windbreak; self-seeds readily
