Botanical Name: Acalypha wilkesiana and Hybrids
Some common names for this plant are Copperleaf, Fire Dragon and Jacob's Coat. Coppery red foliage is the hallmark of spectacular Copper Plant. However, there are dozens of cultivars to choose.
You'll find varieties with leaves streaked, splashed and edged with pink, red, bronze, purple and green, each one prettier than the other. 'Mooreana' has deeply veined maroon leaves with serrated edges. 'Marginata' features bronze leaves edged with red and 'Can Can' is a popular variety splashed with dark pink and creamy white.
Those vibrant leaves can grow up to 5 in (13 cm) long, often with sawtoothed edges.
Cut it back. Acalypha wilkesiana is a vigorous grower. You'll have a big shrub before you know it, so it's a good idea to prune it back by half every spring. You'll get more beautiful foliage this way -- pruning encourages a flush of new stems and leaves. Do not pinch off growing tips, though; this plant branches out naturally.
Repot in spring. Move the plant up one pot size when its roots fill the pot. If you see roots growing through the drainage holes, it's definitely time to repot.
Watch for pests. Check for mealy bugs and spider mites. If you see any signs of pests, isolate your plant and treat any infestation immediately. Raising the humidity in winter will help to prevent an invasion of spider mites that are attracted to dry conditions. The most efficient way to raise humidity for houseplants is to use a cool-mist room humidifier.
Keep it warm in winter. Copperleaf plant is an evergreen perennial that likes warmth and sunlight year-round. This tropical native will tolerate a minimum of 60°F/16°C in winter, but prefers warm temperatures like we do. Growth is slower, so water sparingly in winter and stop fertilizing till spring.
Origin: Java and New Guinea
Height: Up to 6 ft (1.8 m) if not cut back
Light: Bright light is essential for good leaf color. Put your plant where it'll get plenty of light, but protect plant from hot midday sun, which may cause brown scorch marks on leaves. Filtered light from a south- or west-facing window will give it the light it needs.
Water: Keep the soil evenly moist year-round, but take care not to overwater. Soggy soil will cause Acalypha wilkesiana to wilt, and may lead to root rot. It's a good idea to use a pot with a drainage hole; water thoroughly, then empty drainage tray. Water less in winter, but don't allow Copperleaf plant to dry out or leaves may fall off.
Humidity: Moderate to high (above 50% relative humidity). If the air is dry, especially in winter, use a cool-mist humidifier or pebble tray.
Temperature: Average to warm 65-80°F/18-27°C year-round. Copperleaf will tolerate temps as low as 60°F/16°C.
Soil: Good-quality potting mix.
Fertilizer: Feed every 2 weeks spring through fall with a balanced water-soluble fertilizer.
Propagation: Take 3 in (8 cm) stem tip cuttings in early spring and pot them in equal parts horticultural sand and peat moss. Use a heat mat to maintain a steady 75°F/24°C.
