The Alocasia Cuprea — the Mirror Plant — is one of the most otherworldly-looking aroids in cultivation. Its thick, corrugated, heart-shaped leaves have a metallic, iridescent coppery-green sheen on the upper surface, with deep, recessed veins that appear almost black from certain angles. Turn a leaf over and the underside is a rich, deep maroon-burgundy — a hidden drama that makes every leaf a two-sided spectacle. The name says it all: cuprea is Latin for copper. Native to the slopes of Borneo's rainforests, where it developed its metallic sheen to capture filtered canopy light, it stays beautifully compact at 30–60 cm — a jewel aroid in every sense.

💡 Why the Leaves Are Metallic — It's a Survival Adaptation The iridescent, mirror-like sheen of Alocasia Cuprea is not just decorative — it is an adaptation. Growing on the shaded forest floor, the plant evolved a metallic upper surface to maximise reflection and capture of the dappled light filtering through the canopy. The deeper and richer the leaf colour, the more efficiently the plant is photosynthesising.

☀️

Light

▾

Bright indirect light — an east or west-facing window is ideal. The metallic sheen is most vivid in good light; in low light it dulls and growth slows. No direct sun — scorches the leaf surface and fades the copper colouring. A grow light works well.

💧

Watering

▾

Allow the top third of soil to dry before watering — slightly more moisture-tolerant than Black Velvet but still very sensitive to overwatering. Water thoroughly then empty the saucer. Filtered or rainwater strongly preferred. Reduce in winter.

💦

Humidity

▾

65–80% preferred — one of the more humidity-demanding jewel aroids. A humidifier is the most reliable solution. Pebble tray and morning misting also help. Keep away from AC vents. Low humidity causes crispy edges and dulls the metallic finish.

🌱

Growing Media

▾

Very well-draining aroid mix: 35% potting soil, 30% perlite, 20% orchid bark, 15% coco coir. The wild habitat on sloped terrain means drainage is non-negotiable. pH 5.5–7.0. Small pot preferred — oversized pots hold excess moisture. Repot every 1–2 years in spring.

🌾

Feeding

▾

Balanced liquid fertilizer at half strength every 4–6 weeks in spring and summer. Apply to moist soil. Flush soil every 3 months. Stop feeding in winter. Remove any flowers that appear — they divert energy away from the foliage.

🌱 Corms — Don't Throw These Away Small bulb-like corms at the soil base are baby plants. Leave them to grow or carefully separate and pot individually once 1–2 cm wide.

🍂 Winter Dormancy — Possible If Conditions Drop Below 18°C or in very low light, Cuprea may drop leaves and go dormant. The rhizome stays alive — reduce watering, stop feeding, keep warm. New growth returns in spring. Do not discard the pot.

⚠️ Common Issues & Quick Fixes

Metallic Sheen Fading or Leaves Looking Dull

▾

Insufficient light or low humidity — both dim the iridescent finish. Move to a brighter spot and boost humidity. Dusty leaves also look dull; wipe gently with a soft damp cloth. The sheen is at its best in bright indirect light with high humidity.

Yellow Leaves

▾

Usually overwatering — let the top third dry and ensure good drainage. One older leaf yellowing as a new one opens is normal. Widespread yellowing with soggy soil means root rot — unpot, trim black roots, repot in fresh well-draining mix.

Crispy Brown Leaf Edges

▾

Low humidity or tap water minerals. Boost humidity urgently — this plant is particularly sensitive to dry air. Switch to filtered or rainwater and flush soil with plain water to clear salt build-up.

Spider Mites or Mealybugs

▾

Spider mites are the most common pest — low humidity is the main trigger. Wipe leaves with a soft damp cloth, spray with diluted neem oil every 5–7 days for 3 weeks. A monthly shower rinse helps prevent infestations and keeps the metallic surface clean.

Slow or No Growth

▾

Cuprea is a slow to moderate grower — 1 new leaf every 4–6 weeks in good conditions is normal. Ensure bright indirect light, consistent warmth above 18°C, and correct humidity. Do not repot unnecessarily — root disturbance causes significant setbacks.

1 Alocasia Cuprea

Size: 5-8 inches
(Plant sizes may vary slightly based on seasonal growth, individual plant characteristics, and current stock.)

Difficulty: Moderate

Light:

This plant thrives in bright indirect light, which means it needs a well-lit space without harsh direct sunlight. Ideal locations include east or north-facing windows, or spots near south or west-facing windows with filtered light through a sheer curtain to protect its foliage.

Water:

Water when the top 1–2 inches of soil feel dry. Avoid overwatering & ensure pots have drainage holes. Frequency may vary with season and light, roughly once every 5–10 days.

Growing Media:

30–40% Coco Coir/Peat Moss: For moisture retention.
20–30% Perlite/Pumice: Ensures excellent drainage and aeration.
20–30% Orchid Bark (small): Promotes airflow and mimics natural conditions.
10–20% Vermicompost/Compost: Provides slow-release nutrients.

Optional: A handful of horticultural charcoal for added benefit. This blend supports healthy roots and prevents rot in our high humidity.

Feeding & Fertilization:

For these plants, use a balanced liquid fertilizer (such as 20-20-20 or 10-10-10) diluted to half strength, applied every 2–3 weeks during the growing season. They respond well to consistent, light feeding to support their bold foliage.

Mix in well-aged compost or vermicompost into the topsoil every 4–6 weeks to enrich the medium and provide steady organic nutrition. Avoid fertilizing in winter when growth slows down.
