Columnea arguta

A striking epiphytic gesneriad from the cloud forests of Central America, with gracefully trailing stems densely clothed in small glossy leaves and vivid tubular red to orange-red flowers. An excellent choice for hanging baskets where its cascading habit can be fully showcased.

• Light: Bright, indirect light; avoid direct sun. Consistent bright light promotes prolific flowering.
• Temperature: Intermediate growing. 60–75°F (15–24°C); protect from temperatures below 55°F (13°C). Cooler nights can help trigger blooming.
• Humidity: 60–85%; benefits from elevated humidity. A humidifier or pebble tray helps maintain optimal conditions.
• Watering: Keep substrate evenly moist but never waterlogged; ensure excellent drainage. Avoid wetting the foliage directly. Reduce slightly in winter.

Additional Notes:

Grow in a hanging basket with a well-draining mix (coco coir, perlite, and fine bark). Fertilize monthly during the growing season. Trim occasionally to maintain a full, bushy habit.
