There are plants that can also be used in the Koi fish pond but they will not be visible to us.

Water Crowfoot is one of the underwater plants, it lives under the water line and can be bought in a local pet shop.

Underwater plants have useful functions like feeding your Koi fish, fight algae or supply oxygen to the water. They are low maintenance, survive throughout Winter and the pond can benefit a lot from them.
