Cryptocoryne parva is the smallest crypt, and one of the very few species whose leaf colour and form does not change significantly when the environment changes. When cultivated emerged, the plants have wide lanceolate leaf blades, the submersed forms of the leaves are very narrow. Needs more light than most other crypts.
The plants are planted only a few centimetres apart so they form an uninterrupted low carpet after around six months. A recommendable very slow grower for the foreground, also nice as small bush in the areas where the hardscape borders on the substrate.
