Shade-loving Coleus Black Dragon

Plectranthus scutellarioides 'Black Dragon'

flower

Black Dragon Coleus is a striking foliage plant with deep burgundy to near-black leaves with vibrant lime-green or chartreuse margins and veining. This compact, shade-tolerant cultivar is prized for dramatic color contrast in beds, containers, and shaded garden areas. It produces small purple flower spikes but is grown primarily for its spectacular leaf color.

Growing Conditions

☀️
Sun: Partial to full shade; 2-4 hours of indirect sunlight daily. Black Dragon tolerates deeper shade than most coleus varieties but develops better color with some morning light.
💧
Water: Keep soil consistently moist but not waterlogged. Water when top inch of soil feels dry. Reduce watering in winter or dormant periods. Avoid letting soil dry completely, as coleus wilts quickly.
📏
Spacing: 12 inches
📅
Days to maturity: 30-45 days to full ornamental size
🌱
Planting depth: 1/4 inch for seeds; plant transplants at same depth as nursery pot

Soil

Type: Well-draining, fertile loamy soil
pH: 6.0-7.0
Amendments:
Peat moss or coco coir Compost Perlite for improved drainage Balanced slow-release fertilizer

Growth Stages

1

Seedling

1-2 weeks

Tiny 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.

2

Vegetative Growth

3-4 weeks

Plant 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.

3

Establishment

Ongoing throughout season

Plant 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.

4

Flowering

4-6 weeks or throughout warm season

Small 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.

5

Maintenance & Decline

Late summer through fall

Plant 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.

Common Pests

  • Inspect regularly; remove with rubbing alcohol on cotton swab. Spray with neem oil or insecticidal soap every 7-10 days. Isolate affected plants.

  • Use yellow sticky traps to monitor. Spray undersides of leaves with neem oil or horticultural oil. Ensure good air circulation.

  • Increase humidity; mist foliage regularly. Spray with miticide or neem oil. Remove heavily infested leaves.

  • Scrape off manually with soft brush. Spray with horticultural oil in winter dormancy or neem oil during growing season.

  • Let soil surface dry slightly between waterings. Use yellow sticky traps. Apply bacillus thuringiensis israelensis (BTi) to soil if infestation occurs.

Uses

🎨

Shade Garden Solutions

Craft

Solves the common gardening challenge of adding color and interest to difficult shade areas where flowering plants struggle to thrive. [source]

🦋

Pollinator Support

Wildlife

Small purple flowers attract bees and other pollinators when allowed to bloom, providing late-season food sources in shade gardens. [source]

🍳

Edible Ornamental (Limited Use)

Culinary

While some coleus species have culinary applications, Black Dragon is primarily ornamental. However, the leaves are non-toxic and can be used as a decorative garnish, though flavor is minimal. [source]

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.

Fun Facts

  • 🌱 Black Dragon was developed through selective breeding to maximize the dark burgundy-black leaf coloration while maintaining the vibrant lime-green margins, making it one of the most dramatically colored coleus cultivars available.
  • 🌱 Coleus cuttings root so readily in water that Black Dragon can be propagated in a glass of water, making it an ideal plant for sharing with other gardeners and for creating new plants throughout the growing season.
  • 🌱 Unlike most ornamental plants, Black Dragon actually thrives in shade, making it one of the few truly shade-loving foliage plants available for gardeners struggling with dark corners and under-tree planting areas.
