Anthurium Coriaceum

Anthurium coriaceum is a bold, terrestrial “bird’s‑nest” Anthurium recognized for its thick, leathery leaves and upright rosette form. Native to Brazil, it develops stiff, elongated foliage that gives the plant a sculptural, architectural presence. Its durability and tolerance for a wider range of conditions make it one of the more forgiving large‑leaf Anthuriums for collectors.

Light

• Bright, indirect light is ideal.
• Handles gentle morning sun due to its thicker leaf texture.
• Insufficient light leads to stretched, weak growth.

Water

• Water when the top 2–3 inches of substrate dry.
• Avoid prolonged saturation; this species dislikes soggy soil.
• More drought‑tolerant than velvety Anthuriums thanks to its leathery leaves.

Humidity

• Thrives at 60–80%.
• Tolerates average household humidity but grows faster and cleaner in higher humidity.

Temperature

• Optimal range: 65–85°F.
• Avoid cold drafts; growth slows below 60°F.

Soil

• Prefers a chunky, fast‑draining terrestrial mix.
• Ideal components:
  • Orchid bark
  • Pumice or perlite
  • Coco chips
  • Small amount of peat or coco coir
• Appreciates structure and moderate moisture retention, but still requires excellent aeration.

Fertilizer

• Feed every 2–4 weeks during active growth with a balanced liquid fertilizer.
• Slow‑release pellets also work well.

Growth Habit

• Forms a tight rosette of upright, rigid leaves.
• Mature leaves become large and heavy, creating a vase‑like silhouette.
• Growth is moderate but steady under good conditions.

Common Issues

• Yellowing leaves: overwatering or poor drainage.
• Brown tips: low humidity or underwatering.
• Pests: generally resilient but may attract thrips or mites in dry conditions.

Toxicity

• Toxic if ingested; keep away from pets and children.
