Limnophila sessiliflora

Limnophila sessiliflora is a beautiful and undemanding plant from Southeast Asia.

A great alternative to Cabomba, which doesn't require much light. The stems grow quickly up to 40 cm tall and become 3-4 cm wide. The plant generally grows leggy in low light, but this can be counteracted to some extent by stimulating growth with added CO2. It looks best when planted in groups.
Limnophila sessiliflora used to be called "Ambulia".
