Overview
Coleus is native to Southeast Asia and is prized for its vibrant, multi-colored leaves. It can be grown as a colorful annual outdoors or as a houseplant. Modern varieties are more sun-tolerant than older types.
Care Guide
Light
Bright indirect light or partial sun. Some newer varieties can handle more sun. Too little light causes leggy growth and dull colors.
Water
Keep the soil evenly moist. Do not let it dry out completely, especially in warm weather.
Soil
Rich, well-draining soil. A good quality potting mix works well for containers.
Temperature
Prefers 65–75°F (18–24°C). Protect from temperatures below 50°F. Treat as an annual in cooler climates.
Fertilizer
Feed every 2–4 weeks during the growing season with a balanced fertilizer to keep the foliage colorful and vigorous.
Pinching
Pinch the tips regularly to encourage bushy growth and prevent the plant from becoming leggy. Remove flower spikes to keep energy in the leaves.
Propagation
Extremely easy from cuttings. Simply snip a stem and place it in water or moist soil. Roots form in about a week.
Common Problems
- Leggy growth – Not enough light or the plant needs pinching.
- Faded colors – Insufficient light.
- Wilting – Usually underwatering, especially in hot weather.
- Mealybugs or aphids – Check regularly and treat early.
