Here's a great article from Tropica about this plant written by our friend and brilliant aquascaper George Farmer: https://tropica.com/en/articles/hygrophila-compact/

A very compact variety of Hygrophila corymbosa, with the leaves set close to the stalk.

Forms numerous side shoots, enhancing the compact appearance. The leaves are a dark brownish-green, when the plant leaves the nursery, but after a transitional period in the aquarium they turn pale green and silver-white on the underside.

In strong light, the newest leaves may become reddish brown and in dimmer light, the oldest ones die away after a while. New side shoots often forms to replace the old ones.

Pots are brimming with plants and have lots of mass and healthy,
well-developed roots.
Most pots can be divided into several portions or individual plants which are planted separately.
