Growth Stages

1

Establishment

4-6 weeks

Young transplants with small rosettes of colorful foliage beginning to develop their characteristic caramel and burgundy mottling.

Water regularly to keep soil moist but not soggy. Mulch lightly around base (not over crown). Protect from extreme temperature fluctuations.

2

Vegetative Growth

2-3 months

Rosette expands significantly, with mature foliage color intensifying. Plant becomes fuller and more bushy with each leaf adding to the caramel-swirl pattern.

Maintain consistent moisture. Deadhead faded flowers to encourage repeat blooming. Apply balanced fertilizer monthly during growing season.

3

Flowering

4-8 weeks (spring to early summer)

Delicate pink to coral flowers emerge on tall, slender spikes rising above the foliage canopy. Blooms are small but numerous and airy.

Continue regular watering. Deadhead spent flower spikes to promote additional blooms. Flowers attract pollinators.

4

Summer Dormancy

Variable, 2-4 months

After flowering, plant enters a slight slowdown period. Foliage remains vibrant; growth slows in heat, especially in warmer zones.

Reduce watering slightly if temperatures exceed 85°F. Provide afternoon shade in hot climates. Deadhead any remaining flowers.

5

Fall/Winter Transition

3-4 months

Foliage becomes even more richly colored as temperatures cool, displaying deeper burgundy and bronze tones mixed with caramel hues. Plant enters semi-dormancy.

Reduce watering as growth slows. Do not cut back foliage—leave it for winter color and protection. Remove dead leaves at base only if needed.
