Growth Stages

Seedling

3-4 weeks

Tiny rosettes with fine needle-like leaves emerge from soil. Growth is slow initially.

Keep soil lightly moist but not wet. Provide bright light. Thin seedlings to prevent damping off.

Vegetative Establishment

8-12 weeks

Dense, low mounds of fine evergreen foliage develop, resembling ornamental grass. Plant grows outward in a compact dome.

Water moderately, allow soil to dry between waterings. No fertilizing needed—poor soil is actually preferred. Remove any dead or damaged leaves.

Budding & Flowering

8-12 weeks (spring to early summer, sometimes reflowering in fall)

Slender, leafless flower stems emerge from the foliage mounds, each topped with a tight pompom flower head in pink, red, or white.

Maintain consistent moisture during blooming for best display. Deadhead spent flowers to encourage more blooms and extend season. Avoid overhead watering.

Seed Development & Dormancy

Variable; dormancy continues through winter

Flowers fade and seeds develop if not deadheaded. Foliage remains evergreen through winter, turning slightly bronze or reddish in cold climates.

Can leave seed heads for wildlife or remove for tidiness. Reduce watering in winter. No feeding needed. Plant is fully hardy and requires no winter protection in most zones.

Spring Renewal

4-6 weeks

New growth emerges as temperatures warm; flower stems begin forming again.

Cut back any dead or damaged foliage from winter. Divide congested plants in early spring. Resume regular watering as growth accelerates.
