Hivernage
Keep the plant in a consistently warm, humid environment throughout the winter months. Avoid letting the soil dry out completely.
En pot
It is best grown in a small, sealed glass container or a pot sitting in a tray of distilled water.

Seed

  1. Sow seeds on the surface of moist, peat based media.
  2. Maintain high humidity with a clear cover.
  3. Provide bright, indirect light until germination.

Division

  1. Gently separate the plant clumps during the growing season.
  2. Ensure each division has a portion of the root system.
  3. Replant immediately into fresh, damp substrate.

Group carnivorous plants together in a dedicated bog garden or terrarium to simplify their specific moisture and light needs.

Bonnes associations

  • Drosera — They share similar requirements for high humidity and boggy soil conditions.
  • Pinguicula — These plants thrive in the same specialized carnivorous plant environment.

Espèces similaires

  • Genlisea hispidula — It shares the same unique subterranean trapping mechanism.

Ce qu'on demande souvent

Does it need to be fed?
No, it captures its own nutrients from the soil.
Can I grow it in a regular pot?
It requires a specialized bog setup or a sealed terrarium to maintain high humidity.

D'où vient le nom

The genus name Genlisea honors the French writer and educator Stephanie Felicite du Crest de Saint Aubin, Comtesse de Genlis. The specific epithet aurea refers to the golden yellow color of its flowers.

Bon à savoir

  • It is commonly known as a corkscrew plant because of its unique trap structure.
  • The traps are entirely subterranean and lack chlorophyll.
  • It thrives in nutrient poor, waterlogged soils.
  • The flowers are held on tall, slender stalks above the foliage.
