Growth Stages

1

Seedling

2-3 weeks

Small plants emerge with oval cotyledons; true leaves begin appearing with purple coloration

Keep soil moist and warm (70-75°F); provide bright light; thin seedlings to proper spacing once first true leaves appear

2

Vegetative Growth

3-4 weeks

Bushy plant develops multiple stems with deeply ruffled purple leaves; no flowers present

Pinch off growing tips regularly to encourage bushier growth; maintain consistent moisture and fertilize every 2-3 weeks with balanced fertilizer

3

Pre-Flowering

2-3 weeks

Plant continues expanding; flower buds begin forming at terminal points; leaf production slows slightly

Pinch off flower buds to extend leaf production; continue regular watering and feeding; monitor for pests

4

Flowering

Throughout summer until frost

Small, delicate purple or white flowers bloom on spikes; leaves mature to full purple color intensity

Remove flower spikes promptly if leaf production is the priority; allow some flowers to remain for ornamental appeal and pollinator attraction

5

Peak Harvest

Until frost kills plant

Plant reaches full maturity with maximum leaf size and deepest purple color; continuous flowering

Harvest regularly to prevent flowering and maintain tender leaf production; deadhead spent flowers; continue feeding and watering consistently
