If you’re looking for a houseplant that truly stops people in their tracks, you need to meet the anthurium metallicum. This stunning metallic leaf plant is unlike any other foliage in your collection, with its dark, iridescent leaves that seem to change color in the light.
It’s a tropical beauty that makes a real statement. But don’t let it’s exotic looks intimidate you. With the right know-how, you can keep it thriving for years to come.
Anthurium Metallicum
Native to the rainforests of Colombia, the Anthurium metallicum is a terrestrial aroid. This means it grows on the forest floor rather than up in the trees. Its most famous feature is, of course, its foliage.
The large, heart-shaped leaves have a velvety texture. Their color is a deep, bronzy-green with a striking metallic sheen that can appear coppery or bluish depending on the angle of light. New leaves often emerge a bright, luminous green before developing their characteristic dark, shiny finish.
Why the Leaves Shine
That incredible metallic look isn’t just for show. In it’s native habitat, the unique leaf structure helps the plant manage light. The textured surface and iridescence may help diffuse intense sunlight filtering through the canopy, protecting the leaf tissues. It’s a perfect example of nature combining beauty with function.
Finding Your Plant
While once very rare, this anthurium is becoming more available from specialty nurseries and online plant shops. Be prepared for a higher price tag than common houseplants, as they are slower growers. Always buy from a reputable seller to ensure you get a healthy, well-established plant.
Caring for Your Stunning Metallic Leaf Plant
Success with the anthurium metallicum comes down to mimicking it’s natural rainforest floor environment. Think consistent moisture, high humidity, warmth, and dappled light. Here’s how to get it right in your home.
Light: The Golden Rule
This is the most important factor for maintaining that gorgeous metallic sheen. Too much direct sun will scorch the leaves, fading their color. Too little light, and the plant will become leggy and lose it’s vibrant appearance.
- Ideal Spot: Bright, indirect light is perfect. A north or east-facing window is often excellent.
- Good Option: A few feet back from a south or west window, filtered by a sheer curtain.
- Signs of Trouble: Yellowing leaves mean too much light. Stretched stems and small, dull leaves mean too little.
Water & Humidity: Creating a Tropical Microclimate
This plant loves moisture but hates soggy feet. The goal is consistently damp soil, not wet.
- Watering Method: Water thoroughly when the top 1-2 inches of soil feel dry. Always let excess water drain away completely—never let the pot sit in a saucer of water.
- Water Quality: Use room-temperature water. Rainwater or distilled water is best, as they are sensitive to mineral buildup from tap water.
- Humidity Needs: Aim for 60% humidity or higher. This is non-negotiable for healthy growth.
To boost humidity, group plants together, use a pebble tray, or invest in a small humidifier placed nearby. Misting is not very effective and can promote fungal spots on those velvety leaves.
Soil & Potting: The Foundation of Health
The right soil mix prevents root rot, which is the biggest threat to your plant. You need a mix that retains some moisture but drains incredibly fast.
A great DIY recipe is:
- 2 parts high-quality orchid bark (for aeration)
- 1 part coco coir or peat moss (for moisture retention)
- 1 part perlite or pumice (for drainage)
- A handful of horticultural charcoal (to keep the mix fresh)
Repot every 2-3 years in spring, or when you see roots circling the pot. Only go up one pot size (1-2 inches larger in diameter) to avoid excess wet soil.
Feeding & Temperature
Feed your anthurium metallicum monthly during the growing season (spring and summer) with a balanced, diluted liquid fertilizer. Reduce feeding to every other month in fall and stop in winter.
Keep it warm! This plant prefers temperatures between 65°F and 80°F (18°C – 27°C). Protect it from cold drafts and sudden temperature drops, which can cause stress and leaf loss.
Common Problems and Simple Solutions
Even with great care, you might encounter an issue. Here’s how to troubleshoot.
Yellowing Leaves
This is usually a sign of overwatering. Check the soil moisture and ensure your pot has drainage holes. Let the soil dry out a bit more between waterings.
Brown, Crispy Leaf Edges
Low humidity is the most likely culprit. Increase the moisture in the air around your plant using the methods mentioned above. It could also be from using tap water with high fluoride or chlorine.
Pests
Watch for common houseplant pests like spider mites, mealybugs, and scale. The velvety leaves can sometimes attract them. Wipe leaves gently with a damp cloth regularly to deter pests. For infestations, treat promptly with insecticidal soap or neem oil.
Lack of Growth or Small Leaves
This often points to insufficient light or a need for fertilizer. Assess your light situation first, then consider if you’ve been feeding it properly during the growth season.
Propagation: Sharing the Beauty
You can propagate your anthurium metallicum by division when you repot it. This is the easiest and most reliable method.
- Gently remove the plant from it’s pot and brush away the soil to expose the root system.
- Look for natural divisions—sections with their own roots and at least one or two leaves.
- Using clean, sharp scissors or a knife, carefully separate the division from the main plant.
- Pot the new division in it’s own small container with fresh, well-draining aroid mix.
- Keep the new plant in a warm, humid spot and water lightly until you see new growth, indicating it has established.
Frequently Asked Questions
Is the anthurium metallicum toxic?
Yes, like all anthuriums, it contains calcium oxalate crystals which are toxic if ingested. Keep it out of reach of pets and children.
How often does the metallic anthurium grow new leaves?
