Anthurium crystallinum (Big)

One of the most iconic Anthuriums in cultivation. This is a large-size specimen — the broad, deeply cordate leaves already reach an impressive scale, displaying the species’ signature thick, crystalline white venation in full expression over a deep green velvety surface. A statement plant for any serious collection.

• Light: Bright indirect light; avoid direct sun. Thrives near an east- or north-facing window, or under grow lights.
• Temperature: Intermediate-warm growing — 65°F–82°F (18°C–28°C). Protect from temperatures below 60°F (15°C).
• Humidity: 70–90%. Use a humidifier or high-humidity enclosure for best results. Avoid dry air from heating or AC vents.
• Watering: Water thoroughly when the top inch of the substrate feels dry. Use a well-draining, chunky aroid mix. Never let roots sit in standing water.
• Growth Habit: Upright; produces large cordate leaves that become increasingly imposing with age. Benefits from a sturdy moss pole or totem to support its substantial foliage.

Additional Notes:

The thick, bright white venation forms a bold geometric grid across the entire velvety dark green blade — a pattern that has made A. crystallinum one of the most sought-after aroids in the world. The contrast between the crystalline veins and the deep surface intensifies as the leaf matures.
