Establishment
3-4 weeksYoung plants develop rosette of thin, grass-like evergreen foliage with shallow roots
Keep soil consistently moist but not waterlogged. Provide full sun exposure. Remove any dead leaves from nursery pot.
Vegetative Growth
4-8 weeksDense mounding foliage expands, creating a compact cushion of needle-like leaves
Reduce watering as plant establishes. Ensure excellent drainage. Deadhead any early flower buds to encourage foliage development.
Flowering
6-10 weeksSlender leafless stems emerge from the foliage mound, each topped with a perfect white spherical pompom of tiny flowers
Continue moderate watering during blooming. Deadhead spent flowers to encourage repeat blooming. Ensure good air circulation.
Peak Bloom & Repeat Flowering
8-12 weeks or moreMultiple flowers in succession create continuous display of white pompoms above the foliage throughout the growing season
Regular deadheading extends bloom time. Reduce fertilizer to avoid leggy growth. Water sparingly if established.
Dormancy/Winter
3-4 monthsFoliage remains evergreen but growth slows significantly. Plant persists as dormant cushion
No supplemental watering needed. Ensure excellent drainage to prevent winter rot. Divide overgrown plants in early spring.
