Growth Stages

1

Establishment

3-4 weeks

Young plants developing needle-like foliage rosettes and establishing root systems

Keep soil consistently moist but not waterlogged. Protect from extreme heat and drying winds. Space adequately for air circulation.

2

Vegetative Growth

4-8 weeks

Dense, compact mounds of fine, grass-like evergreen foliage forming basal rosettes

Minimal care needed. Ensure excellent drainage. Avoid overfertilizing, which encourages weak growth. Remove any dead foliage.

3

Flowering

6-10 weeks (spring through early summer)

Stiff, leafless stems emerging from foliage bearing tight, spherical flower heads in pink or red tones

Deadhead spent flowers to encourage prolonged blooming. Water at soil level, not on flowers. Provide full sun exposure for best color intensity.

4

Summer Rest

4-8 weeks

Flower production slows or ceases as temperatures rise; foliage remains ornamental

Reduce watering in extreme heat. Mulch lightly around (not over) plants if in hot climates. Maintain good air circulation.

5

Dormancy/Winter

12-16 weeks

Evergreen foliage persists in muted tones; plant enters dormancy in cold climates

No watering needed in most climates. Improve drainage before winter to prevent rot. Remove any accumulated debris. Very hardy and requires no winter protection in zones 3-8.
