Growth Stages

Seedling/Transplant

2-4 weeks

Small rosette of fleshy, light green leaves; plant appears delicate but is hardy

Keep soil lightly moist until established (2-3 weeks); provide bright light; avoid overwatering which causes rot

Vegetative Growth

4-8 weeks

Plant expands into a compact mound with thick, blue-green foliage; no flowers yet

Water sparingly; no fertilizer needed; foliage thickens and deepens in color; pinch back shoots in early summer if bushier plant desired

Flowering

6-10 weeks (June-September)

Flat-topped clusters of small pink flowers appear at stem tips; flowers gradually darken as temperatures cool

Maintain minimal watering; do not deadhead flowers; allow seed heads to develop; flowers transition from pink to deep red over weeks

Fall Color & Seed Set

8-12 weeks (September-November)

Flowers deepen to burgundy-red; seed heads form; foliage may develop purple-red tints in cooler weather

Leave seed heads and dried foliage intact through winter for structure and wildlife benefit; no watering needed

Winter Dormancy

3-4 months

Plant dies back to ground level in severe cold; dried stems and seed heads remain ornamental; foliage absent in zones 3-5

Do not cut back until early spring; dried structure provides winter interest and shelter for insects; resume watering in spring when new growth appears
