An undemanding plant for large aquariums, which thrives in almost any conditions. If it is not pruned it easily grows above the water surface. This makes it particularly suitable for open aquariums. It is most beautiful in groups, but the shoots must not be planted too close, because this will prevent light reaching the lower leaves.

Hygrophila corymbosa (family Acanthaceae) is a large growing plant that  can vary quite a lot with lighting and type. It benefits al lot from high light and a good supply of nutrients in the substrate.  The plants flowers are blue and it flowers easily when it grows through  the surface of the water.
