- The plant forms a dormant bud called a hibernaculum. Keep it in a cool, bright area and ensure the soil remains moist but not waterlogged during the winter months.
- En pot
- It grows very well in pots, provided they are kept in a tray of water and use a minimum 10 cm diameter container.
Seed
- Sow seeds on the surface of damp peat moss.
- Maintain high humidity and bright light.
- Keep the soil consistently moist until germination.
Leaf Cuttings
- Carefully remove a healthy leaf.
- Place the leaf on wet sphagnum moss.
- Cover with a clear lid to maintain humidity until plantlets form.
Always plant in a bog-style container with a mix of peat moss and perlite to maintain the necessary acidity and moisture.
Bonnes associations
- Purple pitcher plant — They share similar requirements for high moisture and acidic, nutrient-poor soil.
- Sphagnum — It provides the ideal acidic, moisture-retentive substrate for sundews.
