Who is the Glush weed?
This pretty plant has large oblong leaves of a refined tender green.
Even if its aesthetic interest is obvious, this species of hygrophilic is not so much appreciated in aquariums where it is completely immersed. Its maintenance is therefore rather difficult in aquariums (you can however let it protrude from the surface if you have an open aquarium). On the other hand, it will grow easily in a paludarium, because its leaves will be able to come out of the water. In this case, flowering can be observed.
Very decorative, this plant can grow up to 60 cm (24) high and 20 cm (8) wide. It is a polymorphous plant, meaning that its appearance varies according to its environment. Here, it is the shape of the leaves that change if the plant is immersed (narrow leaves) or emerged (wider leaves).

How to plant and maintain the Glush weed?
In aquariums, this species is to be reserved for experienced aquarists with large or open aquariums (it can reach 60 cm high!). For a nice look, place it in a group on the background of the aquarium. On the maintenance side, it is therefore necessary:
- fresh water
- strong light
- CO2 diffusion
- very rich soil (fertilizer required)
When all these parameters are met, its growth remains very slow in a completely submerged situation.
The hygrophila costata is therefore rather reserved for use in paludariums. In this case, it is a very easy plant which does not pose any particular problem. It can even flower regularly.
