Quantity: 20 Seeds / pack

Rainbow Mixture coleus (Coleus scutellarioides, also known as Plectranthus scutellarioides) is grown for its foliage: a rainbow of colorful leaf patterns and shades on compact, bushy plants. It brightens shady corners where few flowers thrive — beds, borders, containers, and indoor pots.

Why choose our seeds?

• A wide mix of leaf colors and patterns from one packet
• Thrives in shade where flowering plants fade
• Great for containers, borders, and houseplant use

How to grow Rainbow Mixture Coleus seeds

Choose Your Planting Method

• Indoors: Start about 8 weeks before the last frost — the reliable way.
• Outdoors: Direct sow only after all frost danger has passed and nights are warm.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Humidity dome or plastic wrap
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface and do not cover (or cover with only a whisper of vermiculite) — light is needed for germination.
• No pre-treatment is needed.

Provide the Right Conditions

• Light: Bright, indirect light; keep seeds uncovered.
• Temperature: 70–75°F (21–24°C) for germination.
• Humidity: Cover with a dome until seeds sprout.

Germination

• Seedlings emerge in 10–20 days.
• Remove the cover once sprouts appear and keep soil evenly moist.

Transplanting

• Pot up seedlings as they grow.
• Move outdoors after the last frost; harden off first.
• Space plants 10–12 inches apart.

Care Tips

• Sun: Part shade to shade; morning sun is fine, but harsh afternoon sun can scorch or fade the leaves.
• Water: Water regularly — coleus likes consistently moist (not soggy) soil.
• Fertilizer: Feed monthly with a balanced fertilizer for the boldest color.
• Pinch the stem tips when plants are about 6 inches tall to make them bushy, and snip off flower spikes as they appear to keep the foliage lush.

Foliage Color:

Full leaf color develops about 8–10 weeks after sowing; plants stay colorful through the growing season.
