Seedling
1-2 weeksTiny cotyledons emerge with first true leaves showing early color hints of dark centers
Keep soil moist and warm (70-75°F). Provide bright indirect light. Thin seedlings to prevent crowding.
Vegetative Growth
3-4 weeksPlant establishes root system and develops multiple stems with expanding leaves showing characteristic black-burgundy centers and lime-green margins
Pinch back terminal buds every 2-3 weeks to encourage bushier, more compact growth. Maintain consistent moisture and light shade. Fertilize every 2 weeks with balanced fertilizer.
Establishment
Ongoing throughout seasonPlant reaches mature foliage density with full leaf color expression—deep black-burgundy with vibrant chartreuse edging and veining. Compact, mounded form develops.
Continue pinching flowers if appearance is priority over blooms. Maintain steady watering and fertilization. Adjust light if color fades; move slightly closer to light source.
Flowering
4-6 weeks or throughout warm seasonSmall purple to lavender flower spikes emerge from leaf axils. Flowers are secondary to foliage appeal.
Pinch off flower buds to redirect energy into leaf production and maintain compact form. Remove spent flowers to maintain appearance.
Maintenance & Decline
Late summer through fallPlant continues growing through season but may become leggy or lose color intensity in late season. In frost zones, plant dies back after first frost.
Prune back leggy stems by half in mid-season to rejuvenate. Bring containers indoors before frost in zones 3-9. Overwintering possible indoors with adequate light and moisture.

Harvest Tips
Black Dragon Coleus is harvested for foliage rather than food. Pinch back stem tips regularly—starting 3-4 weeks after planting—to encourage bushier growth and maintain compact form. Remove up to one-third of stems at a time. Cuttings root easily in water or moist soil for propagation. Remove flower spikes as they appear to prioritize leaf color and form. Cut stems just above leaf nodes for best regrowth.
