Seedling
4-6 weeksTiny plants with 2-4 true leaves; very delicate and slow-growing initially
Keep soil barely moist; provide bright light; maintain cool temperatures (60-70°F); protect from direct sun and wind
Juvenile
1-2 yearsYoung shrub developing multiple stems and branching structure; sparse foliage
Gradually acclimate to outdoor conditions; water sparingly; allow soil to dry between waterings; light pruning to encourage bushiness
Establishment
1-2 yearsGrowing shrub with developing woody stems and increased leaf coverage; beginning to form characteristic airy structure
Water regularly during first growing season to establish deep roots; apply 2-3 inches of mulch; minimal fertilizer needed; avoid heavy pruning
Flowering
4-6 weeks in springMature shrub covered in fragrant white to pale pink flowers clustered along stems
Blooms typically appear in spring (April-May); do not fertilize heavily, which reduces flowering; dead-head spent flowers to encourage continued blooming
Mature
Indefinite; shrub can live 20+ yearsFully-developed shrub, 3-6 feet tall and wide, with fine-textured foliage and yearly flowering cycles
Extremely drought-tolerant; prune lightly after flowering to maintain shape; avoid pruning in fall which can stimulate tender new growth prone to frost damage
