Growth Stages

Establishment

6-8 weeks

Young transplants with sparse foliage; active root development underway

Keep soil consistently moist but not waterlogged. Provide afternoon shade in very hot climates. Mulch lightly around base, keeping clear of stem.

Vegetative Growth

3-6 months

Plant develops dense, fine, needle-like foliage; spreading mound shape forms

Reduce watering frequency as roots establish. Light pruning to shape can encourage bushiness. Monitor for pests.

Flowering

9-12 months annually

Small white flowers with dark centers appear along stems; nearly year-round blooming in ideal conditions

Flowers attract pollinators. Deadheading spent blooms encourages continuous flowering. Reduce watering slightly if rainfall adequate.

Mature

Ongoing

Fully established, compact mounding shrub with consistent flowering and dense foliage

Prune in spring to maintain shape and size. Reduce irrigation significantly; water only during prolonged drought. Minimal fertilizer needed.
