Genus: Plectranthus
Species: P. scutellarioides

3. Origin & Distribution

Coleus is native to Southeast Asia, ranging from India to Indonesia, and extending into Australia. It has been widely naturalized in tropical regions worldwide and is one of the most popular ornamental foliage plants in temperate climates.

4. Visual Characteristics

Known for its vibrant and highly variegated foliage, the leaves can be ovate or heart-shaped with toothed, fringed, or smooth edges. Colors include neon green, deep burgundy, vibrant pink, cream, and red, often appearing in complex patterns. The stems are square, a characteristic trait of the mint family.

5. Size & Dimensions

Typically grows to a height of 12 to 36 inches (30–90 cm) and spreads 12 to 36 inches wide. Size can be easily managed through pruning and pinching.

6. Light Requirements

Indoors: Requires bright, indirect light to maintain its vivid colors. Outdoor: Prefers partial shade or dappled sunlight; however, some modern "sun coleus" cultivars can handle full sun if kept sufficiently moist.

7. Watering Needs

Prefers consistently moist but well-drained soil. It will wilt noticeably when thirsty but usually recovers quickly once watered. Avoid letting the soil become waterlogged, as this can lead to root rot.

8. Soil & Potting

Thrives in a rich, loose, well-draining potting soil with a slightly acidic to neutral pH (6.0 to 7.0). Use containers with drainage holes to prevent standing water.

9. Temperature & Humidity

Coleus loves warm temperatures, ideally between 65°F and 85°F (18°C–29°C). It is very sensitive to frost and will perish if temperatures drop below 50°F (10°C). It prefers moderate to high humidity.

10. Fertilization

Feed every 2 to 4 weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half-strength. Reduce feeding in the winter months.

11. Maintenance & Care Level

Care Level: Easy/Low Maintenance. Regularly pinch off the growing tips to encourage a bushier growth habit. Remove any flower spikes as they appear to redirect the plant's energy into its colorful foliage.

12. Growth & Propagation

Fast-growing habit. Propagation is exceptionally easy via stem cuttings; they root quickly in both water and moist soil, making it a favorite for beginners.

13. Common Problems

Susceptible to mealybugs, aphids, and spider mites. Overwatering can lead to root rot or downy mildew. Insufficient light may cause the stems to become "leggy" and the leaf colors to fade.

14. Benefits & Uses

Primarily used for ornamental purposes in home décor, office settings, and landscapes. Excellent for hanging baskets, mixed container gardens, and borders. It adds instant vertical and color interest to any space.

15. Toxicity & Safety

Toxic to pets (dogs, cats, and horses). The sap contains essential oils that can cause skin irritation or allergic dermatitis in humans and gastrointestinal upset if ingested by animals.
