Growth Stages

Establishment

4-6 weeks

Recently planted seedlings or transplants with small rosettes of amber-tinted foliage

Keep soil consistently moist during first 4-6 weeks. Mulch around base to retain moisture and regulate soil temperature. Protect from wind and intense midday sun.

Vegetative Growth

6-12 weeks

Expanding rosettes with increasingly vibrant amber-orange foliage; leaves become more deeply lobed

Water regularly during dry spells. Apply balanced fertilizer monthly during growing season. Monitor for powdery mildew in humid conditions. Foliage color intensifies with temperature drops and increased light.

Flowering

4-6 weeks

Delicate coral-pink or pink flowers appear on thin, upright stems rising 12-18 inches above the foliage mound

Flowers typically appear in April-June depending on location. Deadhead spent flowers to encourage continued blooming. Leave some flowers for ornamental seed heads.

Summer Growth

8-12 weeks

Foliage reaches mature size; leaf color may deepen with heat stress; flowers fade

Provide afternoon shade in hot climates (zones 8-9) to prevent leaf scorch. Maintain consistent moisture. Remove any diseased or damaged foliage.

Fall & Winter Dormancy

12-16 weeks

Foliage color becomes more intense (red-orange tones); growth slows or stops; foliage remains evergreen

Reduce watering frequency as growth slows. Do not remove old foliage; it provides winter protection. In colder zones, mulch over crown in late fall. Remove winter mulch in early spring.
