Flame Nettle
Coleus scutellarioides, commonly called the Flame Nettle, is celebrated for its brilliantly patterned leaves in vivid shades of red, pink, green, yellow, and purple. Grown primarily for its colorful foliage, it adds bold texture to borders, containers, and indoor displays. Though perennial in the tropics, it’s often treated as an annual in cooler climates.

Care Instructions:
The Flame Nettle forms dense, bushy growth with square stems typical of the mint family. Its velvety leaves come in endless color combinations, often edged, veined, or splashed with contrasting tones. Though it does produce spikes of small blue-purple flowers, these are usually pinched off to keep foliage lush. The plant thrives in warmth, humidity, and filtered sunlight, making it a favorite for bright indoor spots and shaded patios.
Light
Prefers bright, indirect light indoors or partial shade outdoors. Too much direct sun can fade leaf color, while too little light results in dull, leggy growth.
Water
Keep soil evenly moist but not soggy. Water thoroughly when the top 2–3 cm of soil feels dry. Avoid allowing the plant to dry out completely.
Soil
Use rich, loose, and well-draining potting soil with compost or peat to retain moisture. Ensure containers have good drainage holes.
Temperature
Thrives in 18–30°C. Avoid cold drafts or exposure to temperatures below 10°C, as leaves may wilt or drop.
Humidity
Prefers moderate to high humidity. Mist regularly or place near other plants to increase moisture in dry indoor air.
Fertilizer
Feed every 2–4 weeks during the growing season with a balanced liquid fertilizer at half strength. Stop feeding in winter when growth slows.
Best Placement Ideas
- Indoor windowsills with filtered light
- Shady garden borders or hanging baskets
- Mixed containers with tropical plants
- As a colorful houseplant centerpiece
Common Issues
- Leaf drop from cold drafts or dry soil
- Faded colors from too much sun
- Leggy stems from insufficient light
- Root rot from waterlogged soil
Things to Watch Out For
- Pinch flower spikes to promote leaf growth
- Avoid overwatering; roots rot easily
- Protect from spider mites and aphids
- Rotate pots for even color exposure
Propagation Tips
Coleus is very easy to propagate from stem cuttings. Take 10–15 cm cuttings below a node in spring or summer, remove lower leaves, and root in water or moist soil. Once roots form, transplant into small pots. Cuttings root quickly and maintain parent color patterns.
Maintenance Tips
Pinch growing tips regularly to keep plants compact and encourage bushy growth. Remove faded or damaged leaves promptly. Re-pot annually in fresh soil, and prune back leggy stems to rejuvenate foliage. For outdoor displays, treat as an annual and replace each spring for best color.
Did You Know?
Before being prized as a decorative plant, Coleus leaves were once used in traditional medicine for their aromatic oils, and their colorful pigments have inspired textile dye patterns across Asia.
