Cryptocoryne parva is an aquatic freshwater plant, often grown in aquariums. It is the smallest known member of the genus Cryptocoryne. Native to Sri Lanka, it grows as a small rosette reaching between 5 and 8 cm. Emersed leaves are a little wider than those growing under water. The spathe is c. 1.5 cm. It grows very slowly even under good conditions and prefers a lot of light.
Two aquariums from Southeast Asia: calm forest streams and peat swamps with soft, brown water, and fast mountain streams with cool, oxygen-rich water.
