Growth Stages

Seedling/Establishment

3-4 weeks

Tiny grass-like leaves emerge and form miniature tufts; plant is very small and delicate

Keep soil consistently moist but not waterlogged; provide bright light; thin seedlings to proper spacing; avoid damping off with good air circulation

Vegetative Growth

6-8 weeks

Compact mound of fine, linear evergreen foliage develops; plant fills out to its mature size; no flowers yet

Water moderately; allow soil to dry slightly between waterings; provide full sun; no fertilizer needed if soil is reasonably fertile

Flowering

8-12 weeks (can repeat if deadheaded)

Delicate pompom flower heads emerge on thin stems in pink and white bicolor; flowers cluster densely above foliage

Deadhead spent flowers to encourage continuous blooming; maintain consistent watering during bloom; avoid overhead watering to prevent flower damage; staking usually unnecessary due to compact habit

Seed Formation & Summer Rest

4-6 weeks

Flowers fade and develop seedheads; foliage may look stressed during hot, dry summers; plant enters semi-dormant state

Deadhead to prevent self-seeding and maintain appearance; reduce watering if plant looks tired; provide afternoon shade in hot climates

Fall/Winter Dormancy

3-4 months

Evergreen foliage persists but growth slows; plant maintains compact shape; may bloom again lightly in fall if conditions are favorable

Minimal watering needed; no fertilizer; ensure excellent drainage to prevent winter rot; do not cut back or prune in fall
