Growth Stages

1

Establishment

2-4 weeks

Young rosettes settling into soil, developing root system

Water lightly after planting; keep soil barely moist for 2-3 weeks. Ensure excellent drainage to prevent rot.

2

Vegetative Growth

Spring through early summer

Rosettes expand and deepen in color; offsets begin forming around the parent rosette

Maintain dry conditions; increase sun exposure to enhance red color. Little fertilizer needed (if any, use very dilute succulent formula).

3

Dormancy/Intensification

Fall through early spring

Foliage darkens to deep burgundy, especially in cool fall/winter temperatures; growth slows or halts

Virtually no watering needed; allow plants to experience cold for best color. Protect from excessive wet rather than cold.

4

Flowering

Summer (June-July in northern zones)

Mature rosettes send up tall flower spikes (8-12 inches) with star-shaped pink or red flowers

Flowering is optional; rosettes are monocarpic (flower once then die), but offsets ensure colony survival. Remove spent flowers if desired.

5

Offset Spread

Ongoing after first season

Young plantlets cluster around parent rosettes, gradually filling in designated area

Allow offsets to root naturally; thin if overcrowded. Separate and replant offsets in spring if propagating.

Companion Planting

Plan your garden →

Plant with:

Sedum varieties (Dragon's Blood, Autumn Fire) Armeria (Thrift) Silene (Catchfly) Saxifraga (Saxifrage) Dianthus (Alpine Pink) Festuca glauca (Blue Fescue) Phlox subulata (Creeping Phlox) Aubrieta (Aubretia)

plants requiring frequent watering (hostas, ferns, hydrangeas) aggressive spreading plants (mint, some ornamental grasses) shade-preferring plants

Common Pests

  • Remove by hand with alcohol-dipped swab; improve air circulation; isolate affected plants

  • Prevent with gritty, well-draining soil; avoid overwatering; ensure pot drainage holes; remove and discard severely affected plants

  • Provide excellent air circulation; remove affected foliage; avoid wetting leaves

  • Increase humidity slightly (minimal); spray with water; use neem oil if severe

Uses
