Seedling
2-4 weeksTiny feathery seedlings emerge with fine cotyledons and developing compound leaves
Keep soil lightly moist but not waterlogged; provide bright indirect light; maintain warm temperatures (65-75°F); thin seedlings if overcrowded
Juvenile Growth
6-12 monthsYoung plant develops characteristic feathery pinnate foliage; stems become woody and establish branching structure
Water moderately during drought; provide light pruning to shape; apply light diluted fertilizer monthly during growing season; ensure excellent drainage
Pre-flowering
3-6 monthsPlant reaches 3-5 feet tall with well-developed woody framework; foliage becomes denser and more robust
Reduce watering frequency; minimal fertilizer needed; light formative pruning acceptable; ensure full sun exposure
Flowering
4-6 weeks, often recurringAbundant golden-yellow fluffy ball-like flower clusters (mimosa-like) appear along stems; flowers attract bees and other pollinators
Do not prune during flowering to preserve blooms; maintain dry conditions; deadhead spent flowers if neat appearance desired; avoid nitrogen-rich fertilizers
Fruiting and Seed Production
8-12 weeksSmall flat seedpods develop and mature to brown; pods contain small flat seeds
Allow pods to mature fully on plant if collecting seeds; harvest pods when dry; store seeds in cool, dry conditions; scarify or soak seeds before replanting
