Seedling
2-3 weeksTiny plants with first true leaves appearing, delicate and requiring gentle care
Keep soil moist, provide bright indirect light, maintain 70-75°F. Avoid direct sun and overwatering which causes damping off.
Vegetative Growth
3-4 weeksPlant develops multiple stems and leaves rapidly; foliage colors become more vibrant and distinct
Pinch off top growth weekly to encourage bushy branching. Feed with balanced fertilizer every 2 weeks. Maintain consistent moisture and bright light.
Established Plant
Until first frost or year-round in warm climatesPlant reaches desired size with full, colorful foliage and well-defined yellow border on burgundy leaves
Continue pinching to maintain bushiness. Remove flower spikes to redirect energy to foliage. Water regularly and fertilize biweekly. Rotate container for even growth.
Flowering
Ongoing if not pruned; typically late summerTall spikes of small purple-blue flowers emerge from leaf axils
Pinch off flower spikes promptly to maintain foliage appeal and prevent plant from becoming leggy. Flowering reduces leaf vitality.
Senescence/Overwintering
Late fall through early springPlant slows growth as temperatures cool; foliage may thin
In cold climates, take cuttings and start new plants, or bring containers indoors before frost. Cut back plant by 1/3 to encourage new growth indoors.
