Cryptocoryne parva

Cryptocoryne parva from Sri Lanka is the smallest of all Cryptocorynes (only 3-6 cm tall and a roset less than 5-8 cm wide). It is one of the few species that does not significantly change its leaf shape and colour depending on cultivation conditions. It needs more light than most other Cryptocorynes because it almost loses its leaf plate under water. So, it must never be overshadowed by other plants.
