Citronella Grass, Ceylon Citronella, Citronella Plant


Cymbopogon nardus, commonly known as Citronella Grass or Citronella Plant, is a tropical, clump-forming, evergreen grass with long, thin, bright green leaves with a citronella-like fragrance when crushed. The plant produces clusters of small, creamy-white flowers on spikes that rise above the foliage. Citronella Grass is best known for its insect-repelling properties, particularly against mosquitoes. The essential oils extracted from the plant's leaves and stems contain compounds known to repel mosquitoes and other flying insects. The oils are commonly used in various products, such as candles, sprays, and lotions, to provide outdoor protection against mosquito bites. In addition, the plant has several traditional medicinal uses and is used in perfumery and flavorings.

  • Grows up to 5-8 ft. tall (150-240 cm) and 3-5 ft. wide (90-150 cm).
  • Performs best in full sun to partial shade in moist, well-drained soils. Some afternoon shade is appreciated in hot summer climates to prevent the leaves from getting burned by intense sun.
  • It is also important to water the plant regularly, especially during dry periods, to ensure healthy growth—Mulch around the base of the plant to retain moisture.
  • In drought conditions, the leaves may become yellow and go dormant.
  • Citronella Grass is typically grown in USDA hardiness zones 10-12 and will not tolerate temperatures below 32°F (0°C). In areas with colder climates, Citronella Grass can be grown as an annual or as a potted plant that can be brought indoors during the winter months.
  • A beautiful ornamental grass for borders, along pathways, or for containers.
  • The lemon-scented oil extracted from the leaves is used to flavor drinks and as a marinade for meat. The fresh leaves can also be used as herbal tea or as a wrapping for steamed dishes.
  • Citronella Grass may benefit from applying a balanced fertilizer once a year to support healthy growth.
  • Virtually disease and pest free
  • Citronella can be propagated by seed, cutting, or division.
  • Toxic to dogs, cats, and horses.
