Ambulia - LIMNOPHILA SESSILIFLORA
Limnophila sessiliflora is a good and undemanding plant from South-East Asia which is a good alternative to Cabomba, which demands a lot of light. Stems grows fast up to 40 cm long and becomes 3-4 cm wide. The plant often grows leggy in poor light, but this can be counteracted to some extent by stimulating growth by CO2 addition. Most beautiful when planted in groups.
In good growing conditions it sends out runners and spreads across the bottom. Limnophila sessiliflora used to be called "Ambulia''.
