Pogostemon helferi, commonly known as "Daonoi" or "Downoi" (Thai for "little star"), is a unique and attractive aquatic plant originating from fast-flowing rivers in northwest Thailand, particularly on limestone. This plant is characterized by its compact growth, curly leaves, and a pleasant light green hue, making it a popular choice among aquarists for the fore- and middleground of aquascapes.

Key Features:

  • Unique Appearance: Compact growth with curly leaves and a light green color, adding a distinctive look to any aquarium.
  • Scientific History: Known to science for over 120 years, but discovered for aquaristic purposes in 1996 by Nonn Panitvong and Arthit Prasartkul in Kanchanaburi, Thailand.

Optimal Conditions:

  • Lighting: Requires sufficient light (0.5-1+ watt per liter) to thrive and maintain its vibrant color.
  • CO2 and Fertilization: Needs ample CO2 supply and adequate levels of fertilizers, including nitrate, phosphate, potassium, magnesium, and iron.
  • Water Flow: Prefers environments with strong water currents, similar to its natural habitat.


  • Easy Propagation: Can be propagated using sharp cutting tools to cut just below a node. Both top and lateral cuttings can be replanted.
  • Planting Tips: Use plant tweezers to avoid bruising and ensure proper planting in the substrate.

Aquarium Benefits:

  • Versatile Placement: Ideal for accentuating the middleground in nano or small aquariums and the foreground in larger tanks.
  • Hardscape Attachment: Can be attached to wood or rocks using nylon thread, ensuring not to draw the thread too tight to avoid bruising.

Care and Maintenance:

  • Avoid Bruising: Handle with care to prevent bruising, which can lead to dieback.
  • Emersed Growth: Suitable for paludariums, where it can be cultivated partially emersed and partially submersed.

Its compact, curly leaves and vibrant light green color make it a standout choice for creating dynamic and visually appealing aquascapes.
