  • Hornwort is most recognizable for its distinctive fern-like foliage. Its stems are long and slender, adorned with whorls of stiff, needle-like leaves. These leaves, often compared to miniature pine needles, are bright green and typically arranged in groups of three to eight.
  • Unlike many aquatic plants, Hornwort lacks true roots. Instead, it possesses tiny structures called rhizoids that help it anchor to the substrate or float freely in the water column.
  • During the warmer months, Hornwort may produce small, inconspicuous greenish flowers. These flowers eventually develop into spore-bearing structures that continue the plant's reproductive cycle.

Adaptability and Care:

  • Hornwort is an incredibly hardy and adaptable plant. It thrives in a variety of water conditions, tolerating a wide range of temperatures, pH levels, and lighting intensities.
  • Its fast-growing nature makes it a valuable asset for aquariums, as it helps absorb excess nutrients and prevent algae growth.
  • Hornwort doesn't require special soil or fertilizers. It readily propagates through stem cuttings, making it easy to share or expand your plant collection.


  • Hornwort's lush green foliage provides a beautiful visual accent to any aquarium or pond.
  • Its dense growth offers hiding places and shelter for fish fry and shrimp.
  • Hornwort's ability to absorb nutrients effectively helps maintain good water quality and keeps algae at bay.
  • Its fast-growing nature makes it an excellent choice for competitive planted tanks.
