Anthurium 'Delta Force' (A. clarinervium × A. pedatoradiatum)

A hybrid with genuine collector pedigree and a fascinating origin story, Anthurium 'Delta Force' was created in the 1990s by Steve Nock of Ree Gardens in Miami, Florida — a cross between Anthurium clarinervium and Anthurium pedatoradiatum from which a single standout seedling emerged bearing a strikingly unusual deltoid, or triangular, leaf shape unlike anything else in the seed lot. That one clone became Delta Force. It inherits the deep green, velvety texture and bold silvery-white venation of A. clarinervium, combined with a distinctly angular, sharply pointed leaf form that gives it an almost geometric, architectural presence. Mature leaves reach 12–18 inches and the lateral venation of the clarinervium parent runs prominently across each leaf, creating the dramatic contrast the clarinervium lineage is famous for — but in a silhouette that is entirely its own. Because the hybrid cannot be reliably reproduced from seed, only clonal propagation and tissue culture preserve the true Delta Force, making every genuine specimen directly traceable to that original Miami plant.

• Light: Bright indirect light. No direct sun — scorches the velvety leaf surface. A bright west or east-facing window is ideal. Tolerates moderate light but grows noticeably slower.
• Water: Water when top half of medium has dried out. Keep consistently moist but never waterlogged. Excellent drainage essential — root rot is the primary threat. Soft or rainwater preferred where possible, as anthuriums are sensitive to mineral buildup.
• Humidity: 65-80% ideal. Higher humidity supports lush growth and keeps the velvety leaf texture at its best. A humidifier is strongly recommended.
• Soil: Chunky, well-draining epiphytic mix — orchid bark, perlite, and coco coir with good aeration. Avoid dense or compacting soils that restrict airflow to the roots.
• Fertilizer: Balanced liquid fertilizer at quarter to half strength every 2-4 weeks during active growth. Light feeder — avoid over-fertilizing, which can damage the root system and cause tip burn.
• Temperature: 70-90°F (21-32°C) preferred. Keep above 60°F. No cold drafts or AC vents. Warm, stable conditions year-round support the best growth.
• Pests: Watch for spider mites, thrips, and mealybugs. The velvety leaf surface can harbor pests — inspect undersides and along the midrib carefully at every watering. Treat promptly with insecticidal soap or neem-based products.
• Toxicity: Toxic to humans and pets if ingested. Contains calcium oxalate crystals causing irritation and swelling of the mouth, throat, and digestive tract.
• Propagation: Clonal propagation by division or tissue culture only — seed propagation does not reliably reproduce the true Delta Force clone. A slow grower; most collectors allow the plant to establish fully before attempting division.
