Hornwort (Ceratophyllum demersum), also known as Coontail, is a fast-growing, aquatic Oxygenating plant. Hornwort grows as a submerged, non-rooting plant. It can be planted at the bottom of your pond, or in small containers using an aquatic media. It's an amazing plant for ponds as it helps not only add oxygen to the water but also emits a hormone to help eliminate algae and clarify the water.

Grows like anacharis, but leaves are longer and thinner, packed tightly in whorls that form plumes at growing ends.

  • Care level: very easy. It can adapt to almost any water type, and can tolerate a wide extreme of temperatures.
  • Grows well in Full Sun to Full shade
  • Very easy to grow
  • Can be tucked into the substrate on the bottom of the pond
  • Great for spawning or as cover/protection for small fish and fry
  • One of the best plants to oxygenate ponds
  • Easily one of the most popular pond and aquarium plants
  • Hardiness Zones: Z5 - Z11

Because of its fast-growing nature, many people use this plant to soak up nitrates in breeding tanks, or provide safe hiding places for fry in community fish tanks. When hornwort is allowed to float at the top of a fish tank, it provides a perfect refuge for tiny fry from hungry adult fish.

Price is per cup, unbanded. Minimum order quantity = 3.

Shipping Expectations: We've found the best success in shipping these when we send them earlier in the week to avoid lengthier shipping times caused by carriers weekend breaks. Orders placed Wed-Friday are likely to be shipped the following Monday.

In excellent shape

Clean - don’t see any snails or other hangers-on. Healthy. Expect they will do exactly as they did last year (when I also ordered Hornwort from you): multiply like crazy and keep my ponds beautifully oxygenated. Thank you!

When these plants got to me they were so green and lush. Now that their in my aquarium which is only been a short while I just had to trim them three days after putting them in. The ones that were cut the ends were long enough to start another bunch. Would buy from again and will be looking on their site for different type of plants.
