Establishment (Newly Planted)
2-4 weeksSmall rosette with minimal watering needs; foliage begins green with hints of color
Water minimally; wait 2-3 weeks before first watering; avoid overwatering which causes rot. Place in full sun location.
Vegetative Growth
3-6 monthsRosette expands, new leaves develop; color intensification begins in response to light and temperature
Water every 2-3 weeks during growing season. Ensure excellent drainage. Monitor for any signs of rot at base.
Color Development
Ongoing, most dramatic in fall/winterFoliage transitions from green to orange, red, and burgundy tones; colors deepen with cool temps and bright light
Maximize sunlight exposure for best coloring. Reduce water as temperatures cool in fall. No fertilizer needed.
Offset Production
Continuous from year 2 onwardMother rosette produces baby rosettes around its base; colony expands outward
Allow offsets to develop naturally. Remove and replant offsets to propagate or control spread.
Flowering (Optional)
Summer; varies by growing conditionsFlowering rosette sends up a tall spike with star-shaped flowers (usually pink or red); rosette dies after flowering
Flowering is not essential for plant longevity; offset rosettes will continue the colony. Allow to flower for pollinator benefit if desired.
