Rainbow Coleus 100 Seeds

Coleus blumei / Plectranthus scutellarioides

Rainbow Coleus is a vibrant foliage plant grown for its dazzling mix of colours—rich burgundy, lime green, and rose often patterned together in dramatic combinations. Unlike flowering plants, coleus is prized primarily for its striking leaves, which bring bold, season-long colour to containers, borders, and shaded garden spaces.

Fast-growing and easy to maintain, Rainbow Coleus creates instant impact in mixed planters and performs beautifully both outdoors in summer and indoors as a houseplant.

Planting Instructions

Indoor Sowing

• Start seeds 8–10 weeks before last frost
• Surface sow — do not cover seeds, as light aids germination
• Keep soil consistently moist and warm (21–24°C)
• Germination: 10–14 days
• Provide bright, indirect light once seedlings emerge
• Transplant outdoors after all danger of frost

Care Tips

• Sun: Partial shade to bright indirect light (some varieties tolerate morning sun)
• Soil: Rich, well-drained soil
• Water: Keep evenly moist; avoid letting soil dry out completely
• Spacing: 10–14 inches apart
• Height: 12–24 inches
• Maintenance: Pinch tips regularly to encourage bushy growth; remove flower spikes to maintain vibrant foliage
• Hardiness: Tender annual in Canada (not frost tolerant)

Rainbow Coleus is perfect for gardeners seeking dramatic foliage colour and low-maintenance performance, delivering bold visual interest from spring through fall.
