Aponogeton rigidifolius is a submerged freshwater aquatic plant from Sri Lanka, grown mainly in aquariums and water gardens. It is distinguished from other Aponogetons by a creeping rhizome rather than a tuber, and it is tough once established.
Aponogeton rigidifolius is a species of freshwater plant native to Sri Lanka. In the wild it grows in deep water at temperatures of 68 to 77 °F (20 to 25 °C) in sandy soil with the water pH at 7.2.
This species is unique amongst the Aponogetons in having an elongated rhizome rather than a tuber; the rhizome creeps along the surface, and from it new leaves sprout. This rhizome can be divided. It needs no rest period but is slow growing, though tough once established. It needs only a moderate light, tropical temperatures, and will tolerate harder water than most other Aponogetons. It is not commonly available but a good plant for the middle to background of an aquarium. It flowers rarely in aquariums.
