Growth Stages

1

Establishment (Spring planting)

4-8 weeks

Young transplants with small rosettes of red-orange foliage establishing root systems

Water consistently, avoid transplant shock by planting in cooler weather or with shade cloth in heat. Monitor soil moisture daily.

2

Vegetative Growth (Late spring to early summer)

6-8 weeks

Rosettes expand with increasingly vibrant red-orange leaves as temperatures warm and light increases

Remove any dead or damaged leaves. Apply 1-2 inches of mulch around (not touching) the crown. Fertilize lightly with balanced fertilizer.

3

Flowering (Late spring to early summer)

4-6 weeks

Delicate pink flower spikes emerge above the foliage mound on thin stems, reaching 12-18 inches tall

Deadhead spent flowers to encourage extended blooming. Ensure adequate water during flowering. Staking usually unnecessary.

4

Summer Color (Mid to late summer)

8-12 weeks

Foliage remains vibrant red-orange and may deepen in color; flowering subsides but new growth continues

Maintain consistent moisture. In hot climates, provide afternoon shade to prevent foliage scorch. Watch for pests in heat stress.

5

Fall/Winter (Autumn through early spring)

20-24 weeks

Foliage may intensify in color with cooler temperatures; leaves persist as evergreen; dormancy sets in

Reduce watering significantly as plant enters dormancy. Do not cut back dead foliage—it provides winter protection. Remove debris from crown area to prevent rot.
