Growth Stages

1

Establishment

4-6 weeks

Young plant with small rosettes and sparse foliage; root system developing

Water lightly but consistently for first 4-6 weeks until roots are established. Provide bright light. Protect from extreme heat initially.

2

Vegetative Growth

Spring through early summer

Plant produces dense mounding foliage with lance-shaped leaves in green, red, or purple tones depending on light and variety

Reduce watering as plant matures. Provide full sun for best color development. Prune lightly to maintain compact shape if desired.

3

Flowering

Summer through fall (June-November)

Produces clusters of small tubular flowers in red, pink, yellow, or bicolor combinations from tips of branches

Continue minimal watering. Deadhead spent flowers to encourage continued blooming. Flowers attract hummingbirds and butterflies.

4

Fall & Winter Dormancy

November-March

Growth slows significantly; foliage may deepen in color; flowering may continue in mild climates

Water sparingly or not at all in cold climates. In zones 8-9, provide some winter protection in harsh years (frost cloth or mulch around base, not covering). Stop fertilizing.

5

Spring Renewal

March-May

New growth emerges from base; plant returns to active growth; flowers may appear in late spring

Resume regular watering schedule. Begin light fertilizing with diluted succulent fertilizer if desired. Remove any dead foliage from winter.
