Anthurium Pap R18 x Carla 5x10

Anthurium 'Pap R18 x Carla 5x10' is a purposefully bred hybrid cross combining the genetics of two select parent lines — Pap R18 and Carla 5x10 — to produce offspring with exceptional foliage character. Expect large, deeply textured leaves with prominent venation, a rich green ground, and the kind of structural presence that defines serious aroid collecting. As a hybrid, each plant carries a unique expression of its parentage, making every specimen a distinct and unrepeatable work of botanical art.

This is a grower's hybrid — sourced from dedicated breeders working at the frontier of anthurium genetics. Ideal for collectors who appreciate provenance, lineage, and the thrill of watching a cross develop into its full potential.

Care Guide

Light

Prefers bright, indirect light. Strong indirect light encourages larger leaves and more defined venation. Avoid direct sun, which can scorch the foliage. An east-facing window or a position set back from a south- or west-facing window is ideal.

Water

Water when the top 1–2 inches of soil are dry. Anthuriums are prone to root rot in consistently wet conditions — ensure thorough drainage after each watering and never allow the pot to sit in standing water. Use filtered or room-temperature water to avoid fluoride sensitivity. Reduce frequency in winter.

Humidity

Thrives in high humidity (65–80%). A room humidifier is the most effective solution. Avoid misting directly on the foliage. Consistent high humidity supports larger leaf development and healthy root growth.

Temperature

Keep between 65–85°F (18–29°C). Protect from temperatures below 60°F (15°C), cold drafts, and air conditioning vents. Stable warmth is key to consistent growth in hybrid anthuriums.

Soil & Potting

Use a chunky, well-aerated aroid mix — orchid bark, perlite, coco coir, and horticultural charcoal in roughly equal parts works well. Excellent drainage and root aeration are essential. Pot slightly snug and repot every 1–2 years as the root system develops.

Fertilizer

Feed every 4–6 weeks during the growing season (spring through early fall) with a balanced liquid fertilizer at half strength. Supplement with calcium and magnesium to support robust leaf and root development. Flush the soil periodically to prevent salt buildup. Withhold fertilizer in winter.

Toxicity

Toxic to cats, dogs, and humans if ingested due to calcium oxalate crystals. Keep out of reach of pets and children.
