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.[1]
The creeping rhizome is cylindrical and about 5 inches (13 cm) thick. The leaves stay submerse, are firm (almost leather-like and seem immune to most fish and snails) about 8 to 23 inches (20 to 58 centimetres) long and 1 to 1.6 inches (2.5 to 4.1 centimetres) wide. The margins of the leaves are flat to slightly undulate with a distinct midrib. In colour they are a dark green to reddish colour. The inflorescence has a single spike with white flowers and small fruits.[2][3]
