Nepenthes Diana is a breathtaking hybrid tropical pitcher plant admired for its brilliantly coloured, flared pitchers and vigorous growth habit. Thought to be a complex hybrid involving Nepenthes maxima and Nepenthes ventricosa (or closely related species), this cultivar showcases the elegance and structure of maxima with the hardiness and adaptability of ventricosa.
The plant produces glossy, lanceolate leaves that give rise to long tendrils, each ending in an exquisite pitcher of rich crimson to deep maroon, often with speckled green undertones and a wide, fluted peristome. The peristome rim is heavily ribbed and highly reflective, appearing lacquered under bright light. Mature pitchers can grow to 1520 cm long, with a graceful, curving silhouette and dramatic colouring that deepens as the plant ages.
Lush, bold, and resilient, Nepenthes Diana is a truly regal hybrid a statement piece that embodies both tropical drama and graceful sophistication.
Nepenthes Diana Care Guide
Light
Thrives in bright, indirect light or filtered sunlight. A few hours of gentle morning or late-afternoon sun will enhance the deep red tones of the pitchers. Avoid intense midday sunlight, which can scorch the leaves, and deep shade, which may reduce pitcher production and vibrancy.
Watering
Keep the substrate consistently moist but not waterlogged. Always use rainwater, distilled water, or reverse osmosis (RO) water, as tap water minerals can harm the plant. Do not allow the soil to dry completely, and ensure good drainage to prevent stagnant water around the roots.
Temperature and Humidity
-
Temperature: Prefers 2230 C during the day and 1520 C at night. Avoid temperatures below 12 C.
-
Humidity: Requires moderate to high humidity (6090%) to maintain healthy leaves and pitchers. Mist daily or use a humidifier, especially in drier environments, to encourage consistent pitcher formation.
Soil and Potting
Use a light, acidic, free-draining mix such as sphagnum moss combined with perlite or orchid bark. This allows air circulation while retaining the moisture Nepenthes roots need. Repot every 12 years in spring to refresh the mix and maintain strong, healthy growth. Avoid fertilised or compacted soil.
Feeding
Nepenthes Diana naturally catches insects such as flies, gnats, or ants. If grown indoors, you can feed a few pitchers monthly with small insects or a drop of diluted orchid fertiliser. Do not fertilise the soil directly this plant derives nutrients exclusively through its pitchers.
Pruning and Maintenance
Remove old, dried pitchers and yellowing leaves to maintain a neat appearance and promote new growth. Trim long vines if necessary to manage shape and size. Wipe leaves occasionally with a damp cloth to remove dust and restore their glossy sheen.
Growth and Maturity
A moderate to fast-growing hybrid, Nepenthes Diana typically reaches 6090 cm in height indoors and can grow larger when given vertical support. It produces pitchers regularly under warm, bright, and humid conditions, rewarding growers with continuous colour and texture throughout the year.
Common Issues
-
Pitchers not forming: Low humidity or insufficient light.
-
Brown edges: Dry air or mineral build-up in water.
-
Yellow leaves: Overwatering or cold stress.
-
Pests: Occasionally aphids or mealybugs; treat promptly with neem oil or insecticidal soap if necessary.
