Stormy Weather Coleus (Solenostemon scutellarioides, now often classified as Plectranthus scutellarioides) is known for its bold, moody foliage: deep burgundy, purple, and bronze tones edged in green. This cultivar offers a powerful visual impact with minimal effort and is valued for being both low-maintenance and versatile.

Planting Guidelines
When to Plant
- After the last frost in spring when temperatures remain above 60°F (15°C), or indoors 6–8 weeks before the last frost date.
Where to Plant
- Shaded garden beds, north or east-facing borders, under trees, or in containers on shaded patios.
- Works well in combination planters due to its compact growth and dramatic coloring.
How to Plant
- Spacing: 12–18 inches apart for good air circulation.
- Depth: Plant at the same depth as it was in the nursery container.
- Water thoroughly after planting.
Light Requirements
- Ideal: Partial to full shade.
- Sun Tolerance: Can handle filtered sunlight or morning sun but may fade or scorch in intense afternoon sun.
- Container Tip: If grown in a pot, rotate periodically for even growth.
Soil and Watering
- Soil: Rich, loose, and well-draining with a slightly acidic to neutral pH (6.0–7.0).
- Watering:
- Keep soil consistently moist but not soggy.
- In hot weather, daily watering may be needed—especially in containers.
- Avoid overhead watering to prevent leaf spots.
Fertilization
- Feed every 4–6 weeks with a balanced, water-soluble fertilizer (e.g., 10-10-10) for lush growth.
- In containers, fertilize monthly during the growing season.
Maintenance
- Pinching: Regularly pinch back tips to promote bushiness and prevent legginess.
- Deadheading: Not necessary; foliage is the main feature.
- Flower Removal: If flower spikes do appear, remove them early to preserve leaf vigor and form.
Pests and Problems
- Aphids, whiteflies, and spider mites may occur—treat with insecticidal soap or neem oil if needed.
- Root rot can be an issue in poorly draining soil or with overwatering.
- Leaf drop or dull color often signals too much sun or drought stress.
Overwintering Tips
- In-ground plants: Typically treated as annuals and replaced each year in cooler climates.
- Indoor overwintering: Take cuttings in late summer or dig up and pot the plant to bring indoors before frost.
- Provide bright indirect light indoors.
- Reduce watering in winter but don’t let the soil dry out completely.
Propagation
- Cuttings: Coleus roots easily from cuttings.
- Take 4–6 inch stem cuttings just below a leaf node.
- Remove lower leaves and place in water or moist potting mix.
- Roots form in 1–2 weeks.
- Transplant into soil once roots are strong.
Landscape and Design Ideas
- Pairing Plants: Combine with lime green or chartreuse plants (like sweet potato vine or heuchera) for contrast.
- Use in Containers: Makes a bold thriller or filler in mixed planters.
- Shade Gardens: Mass plant for a moody, cohesive color palette.
