Floating & Submerged Plants » Submerged Plants » Hornwort

Hornwort (Ceratophyllum demersum) is a very attractive plant in both ponds and aquaria. It grows in long, soft, plumed fronds which can reach two feet in length. This was one of the first plants added to the Pond and grows in abundance. Due to the needle-like leaves koi tend to be less interested in this plant and like anacharis it is an oxygenator plant that competes with algae for the nutrients in the water, thus reducing the amount of algae that will be able to grow.
