Growth Stages

1

Establishment

6-12 months

Young plant with soft, feathery foliage establishing root system

Water regularly to keep soil consistently moist but not waterlogged. Protect from strong winds. Provide light shade in hotter climates during first summer.

2

Vegetative Growth

1-2 years

Plant develops dense, bushy form with finely divided, gray-green aromatic leaves

Prune lightly in spring to encourage bushiness. Remove any dead or diseased wood. Reduce watering once established. Feed with balanced fertilizer in spring.

3

Pre-flowering

4-8 weeks

Plant reaches mature size and begins setting flower buds along branch tips

Reduce nitrogen fertilization to encourage flowering rather than excessive leaf growth. Ensure adequate sunlight. Avoid pruning during this phase.

4

Flowering

6-10 weeks (late spring to early summer)

Abundant clusters (panicles) of small, star-shaped white flowers appear at branch terminals with strong fragrance

Deadhead spent flowers to promote extended blooming if desired, though not essential. Maintain consistent moisture. Plant attracts bees and butterflies.

5

Post-flowering

Rest of growing season

Flowers fade and plant enters period of slower growth; foliage remains ornamental year-round

Allow some flowers to remain for seed development if desired. Reduce watering in autumn and winter. Can prune to shape in late summer after flowering.
