How to Start Coleus from Seed

Growing coleus seeds is surprisingly simple.

1. Sow Indoors 8–10 Weeks Before Last Frost

Coleus seeds are tiny and should be surface-sown.

  • Press seeds gently onto moistened seed-starting mix

  • Do not bury — they need light to germinate

  • Cover with humidity dome or plastic

Germination typically occurs within 10–14 days.

2. Light & Temperature for Germination

Coleus seeds perform best at:

  • 70–75°F

  • Bright, indirect light

  • High humidity

  • Avoid cold drafts

Once seedlings emerge, they will quickly develop their first color-splashed leaves.

3. Transplanting Seedlings

When plants have 2–3 true leaves:

  • Move seedlings into 3–4" pots

  • Maintain even moisture

  • Pinch early for branching

This encourages bushier coleus growth.

4. Outdoor Placement

Coleus absolutely THRIVES in:

  • Shade gardens

  • North-facing beds

  • Under trees

  • Containers

  • Porch planters

They can tolerate some morning sun — but intense direct sun can bleach foliage in many varieties.

Using Coleus in Garden Design

Coleus is a foliage superstar.

You can use it to:

  • Create contrast in green-heavy gardens

  • Anchor hanging basket designs

  • Provide season-long color

  • Fill in shady areas where flowers struggle

  • Pair with begonias, impatiens, caladiums, ivy, and torenia

This is why coleus is a top bedding plant for landscapers and container designers.
