Growth Stages

1

Establishment

1-2 weeks

Young plant with initial leaf formation; small but showing purple coloration

Keep soil consistently moist, provide bright indirect light initially, protect from temperature fluctuations below 60°F

2

Vegetative Growth

4-6 weeks

Plant develops multiple stems and branches; leaves fill in and deepen in color

Pinch back growing tips to encourage bushier growth, gradually increase sunlight, fertilize every 2 weeks with balanced fertilizer

3

Bushing Out

Ongoing with maintenance

Compact, dense foliage formation with full burgundy coloration; well-developed branching structure

Continue pinching back to maintain shape, provide full sun for deepest color, maintain consistent moisture and feeding schedule

4

Flowering

6-8 weeks, sporadic

Small, inconspicuous white or pale purple flowers appear among foliage (not the main ornamental feature)

Pinch off flower spikes if preferring foliage-focused appearance; flowers are minor feature

5

Maintenance
