Maturation
OngoingPlant reaches maximum size (typically 2-4 inches diameter), coloring deepens, leaf texture becomes more pronounced
Maintain consistent bright light and minimal water. Check for pups (baby rosettes) forming around base.
Flowering
Several weeks in spring/summerProduces small tubular flowers in pink, white, or red from leaf axils or on short stalks; flowers appear in spring to early summer
