As a pond specialist, I understand that selecting the best aquatic plants for your pond can be a tough job, which is why in this blog I will tell you everything you need to know about the Iris and its value in the pond!
What kind of aquatic plant is an Iris?
Irises are water purifying pond marsh plants that many people know by the name: Iris. An Iris exists in many different varieties, so they are available in various colors, the Iris or Lis exists namely as: blue Lis, black Lis, yellow Lis, white Lis and pink Lis ... So something for everyone! Because the Iris is a hardy pond plant, it blooms every year and every year just a little more beautiful and fuller. The Iris can grow to about 80 centimeters high and can be planted at a depth of about 20 centimeters. You can plant the water plant at the edge of the pond so it is not too deep, but you can also choose to place the pond plant in the middle of the pond on an elevation. In this way you can turn the Iris into a real eye-catcher in your pond!

Why are pond irises valuable?
Irises are water-purifying pond plants. The name water-purifying says it all, as the pond plant purifies waste products from the pond water. This will reduce nitrate and nitrate concentrations in the water causing the KH value, PH value and GH value in remain stable and the water hardness of the pond water remains balanced. This is important to keep the pond environment healthy. Another advantage is that pond water does not need to be tested when there are sufficient water-purifying oxygen plants such as Lis and Typha in the pond and the pond is well landscaped.
How do I plant a Lis in my pond?
The Iris is a very strong marsh plant that filters the water in the pond. Because the Iris has strong roots it is ideal to place the water plant in a plant filter of water plants. In this way, the water in your pond is naturally filtered and you get the most out of this water purifying aquatic plant. The Lis' tall plant stems make it ideal for sheltering other aquatic plants.
Should I prune a Lis?
An Iris or Lis needs little care, because the water plant is so strong, it always makes it through all seasons of the year without any problems. A tip is to cut all the stems of the Iris in the fall, then the Iris will have no more flowers but the functioning of the water plant remains unchanged. This makes Irises the ideal choice if you are looking for an aquatic plant that will last year after year and bloom again and again.
