If you’re looking for a truly special houseplant that stops people in their tracks, look no further. The anthurium metallicum is a rare metallic leaf plant that looks like living art. Its large, heart-shaped leaves have a stunning, almost iridescent sheen that shifts from dark green to a silvery, brushed metal finish. This isn’t your everyday houseplant, and caring for it requires a bit of know-how. This guide will walk you through everything you need to keep your metallicum thriving.
Anthurium Metallicum
This plant is a true gem from the rainforests of Colombia. Unlike the common flamingo flower anthuriums, prized for their blooms, the metallicum is a foliage superstar. Its velvety texture and reflective surface are its main attraction. The new leaves often emerge with a coppery or reddish tint before maturing into their full metallic glory. It’s a slow grower, but each new leaf is a cause for celebration.
Why It’s So Special and Rare
Several factors contribute to its rarity and high demand. First, it grows naturally in a very limited region. Second, it’s a slow propagator, so growers can’t mass-produce it quickly. Finally, its stunning appearance makes it a top wishlist item for collectors. Getting your hands on one feels like a real achievement.
- Unique Foliage: The metallic sheen is unmatched in the plant world.
- Conversation Starter: It’s guaranteed to draw attention and questions.
- Collector’s Item: A centerpiece for any serious plant collection.
Perfect Growing Conditions
Recreating its native jungle environment is the key to success. Think warm, humid, and bright but not sunny. Getting these conditions right will prevent most common problems.
Light Requirements
Bright, indirect light is non-negotiable. An east-facing window is ideal. A few feet back from a south or west window with a sheer curtain also works. Direct sun will scorch those beautiful leaves, leaving permanent brown marks. Too little light, and the plant will become leggy and lose its compact shape.
Temperature & Humidity
This plant hates the cold. Keep it in a room between 65°F and 80°F (18°C – 27°C). Avoid drafts from doors, windows, or air vents. Humidity is even more critical. Aim for 70% or higher. Here’s how to increase humidity:
- Use a humidifier right next to the plant (most effective method).
- Place the pot on a pebble tray filled with water.
- Group it with other humidity-loving plants.
- Avoid misting too frequently, as water sitting on the velvety leaves can cause spots.
Planting and Potting Mix
The right soil is all about drainage and aeration. Anthurium metallicum is an epiphyte, meaning in nature it grows on trees, not in soil. Its roots need air and hate being soggy.
A perfect mix is chunky and loose. You can make your own with:
- 30% Orchid bark (medium grade)
- 30% Coconut coir or sphagnum moss
- 20% Perlite
- 20% Horticultural charcoal
Choose a pot with excellent drainage holes. Terracotta pots are great because they wick away extra moisture. Repot only every 2-3 years, or when you see roots circling the pot’s bottom. They actually like being a bit root-bound.
Watering and Feeding Schedule
Overwatering is the fastest way to harm this plant. The goal is to keep the mix lightly moist but never wet.
- Check the Soil: Stick your finger about 2 inches into the mix. If it feels dry, it’s time to water.
- Water Thoroughly: Water slowly around the soil surface until it runs freely from the drainage holes.
- Let it Drain: Always empty the cachepot or saucer after 15 minutes. Never let the pot sit in water.
- Reduce in Winter: Water less frequently during the cooler, darker months when growth slows.
For fertilizer, use a balanced, water-soluble formula (like a 10-10-10) diluted to half-strength. Feed it once a month during the spring and summer. Do not feed in the fall and winter. Over-fertilizing can burn the sensitive roots.
Common Problems and Solutions
Even with great care, you might encounter an issue. Here’s how to troubleshoot.
Yellowing Leaves
This is often a sign of overwatering. Check your soil moisture and ensure the pot drains well. Older leaves yellowing and dying off naturally is normal occassionaly.
Brown Leaf Edges or Tips
Low humidity is the usual culprit. Increase the moisture in the air around your plant. It could also be from using tap water with high salts or chlorine; try using rainwater, distilled, or filtered water.
Pests
Watch for common houseplant pests like spider mites, mealybugs, and scale. The velvety leaves can hide them. Wipe leaves gently with a damp cloth regularly to keep them clean and inspect for pests. If you find any, treat immediately with insecticidal soap or neem oil.
Propagation Tips
You can propagate anthurium metallicum by division when you repot it. This is the simplest and most reliable method.
- Gently remove the plant from its pot and brush away the potting mix.
- Look for natural divisions in the root ball, with each section having its own growth point (stem and leaves).
- Using clean, sharp shears or your hands, carefully separate the sections.
- Pot each new division into its own small container with fresh, chunky mix.
- Keep the new plants in a warm, humid spot and water lightly until you see new growth, which indicates the roots have established.
FAQ About the Metallicum Anthurium
Is the anthurium metallicum toxic?
Yes, like all anthuriums, it contains calcium oxalate crystals which are toxic to pets and humans if ingested. Keep it out of reach of curious cats, dogs, and children.
How big does the metallic leaf anthurium get?
Indoors, it typically reaches about 2 to 3 feet in height and spread. The leaves can grow over a foot long in ideal conditions.
Why are the leaves on my metallicum plant not shiny?
Insufficient light or low humidity can dull its signature sheen. Ensure it gets enough bright, indirect light and high humidity. Also, avoid touching the leaves too much, as oils from your skin can affect the velvety texture.
Does it flower?
It can produce a classic anthurium spathe and spadix flower, but it’s usually a greenish color and not particularly showy compared to the spectacular foliage. Most growers remove the flower to let the plant put its energy into leaf growth.
Where can I buy one of these rare metallic plants?
Check specialized online plant shops, Etsy sellers, or local plant nurseries that cater to collectors. Be prepared for a higher price tag due to its rarity. Always buy from a reputable source to ensure you get a healthy plant.
Caring for an anthurium metallicum is a rewarding journey. It asks for a little more attention than a pothos, but the payoff is a breathtaking, living sculpture. By providing consistent warmth, high humidity, and careful watering, you’ll be able to enjoy its mesmerizing metallic leaves for many years to come. Remember, patience is key with a slow-growing treasure like this one.
