Growth Stages

1

Seedling

7-10 days

Tiny seedlings with two seed leaves (cotyledons) emerge and develop true leaves with dark purple coloring

Keep soil moist but not waterlogged. Provide bright light and warm temperatures (70-75°F). Thin seedlings to proper spacing once true leaves appear.

2

Vegetative Growth

14-20 days

Plant develops bushy foliage with distinctive deep purple-black leaves. Compact growth habit is evident.

Pinch off flower buds to encourage bushy leaf growth and prolong harvest. Water consistently and feed with balanced fertilizer every 2-3 weeks.

3

Flowering

Ongoing from 4-5 weeks onward

Spikes of vibrant purple flowers appear at stem tips. Plant reaches mature height of 12-18 inches.

Pinch off flowers as they appear if you prefer leaf production. Allow some flowers to remain for ornamental appeal and pollinator attraction.

4

Peak Harvest

6-8 weeks

Plant is full and bushy with abundant foliage ready for regular harvesting

Harvest regularly by pinching leaves from the top to encourage branching. This extends the productive season and prevents flowering.

5

Decline

In cool climates, replace plant at season's end. In warm zones, heavy pruning or replacement may rejuvenate growth.
