Water wisteria (Hygrophila difformis) is an extremely hardy plant native to the Indian Subcontinent, and one I highly recommend for aquarist to keep in their tank.
Making a great hiding place for small fish and invertebrates. As long as you can provide at least medium intensity light, there’s no reason not to give this plant a try.

Using Water Wisteria In The Aquarium
This species of plant is extremely hardy and is capable of adapting to a wide variety of tank conditions.

Water wisteria loves bright light. It will do best under medium to high lighting.
Water Parameters for Water Wisteria
- pH: 6.5-7.5
- GH: 3-19 dGH
- KH: 3-8 dKH
This is a really fast growing plant. Even without CO2, water wisteria will grow rapidly.
Planting Water Wisteria
There are two ways to keep this plant in your tank.
You can bury the stems of the plant in the substrate. Over time it will grow roots and anchor itself in place.
The other option is to simply grow your water wisteria as a floating plant. It will do best in a calm area where it is not being churned by a strong current.
Propagating Water Wisteria
This plant is propagated by cutting. Simply cut a piece off the top of the plant, leaving several sets of leaves on the old plant.
The cuttings can be buried in the substrate or allowed to grow as a floating plant.
Fertilizer and CO2
Adding a comprehensive plant fertilizer to your water weekly will help your water wisteria grow thick and lush.
This species feeds primarily from the water column and not through its roots. So, you don’t need to bury root tabs in the substrate.

Water wisteria can easily be grown without adding compressed CO2 to your tank. But of course, like most plants, it will grow much faster in a tank with CO2.
But honestly, this stuff already grows pretty darn fast. There’s no need to make an expensive upgrade on your tank just for water wisteria, believe me.
Pro Tip: This plant can help keep your aquarium water clean because it eats up nitrate from the water column to fuel its growth.
Older growth on this plant can be the target of algae that can cover the broad surfaces of the leaves.
You can also spot treat leaves using a dosing syringe and Seachem Excel.
Pro Tip: The active ingredient in Excel, glutaraldehyde, is a powerful algaecide. It will readily kill even some of the most stubborn algaes, like black beard and staghorn algae, when it’s applied directly.
