Aponogeton crispus
BeginnerAponogeton crispus
A large Sri Lankan aquatic plant that grows a rosette of long, wavy-edged leaves from a tuber. It needs no dormant period in aquaria and often flowers, but its leaves can reach the surface, so it suits larger tanks.
About
Aponogeton crispus (Aponogetonaceae) grows in southern India and Sri Lanka in seasonal pools and marshes that fill only in the rainy season, sprouting from a tuber. In the wild it rests in the dry season, but in aquaria it grows without a dormant period. It forms a rosette of long, wavy-edged leaves and is a large species, 30–50 cm tall and 20–40 cm wide, whose leaves can reach and spread over the surface even in deep tanks. Leaf colour ranges from light green to reddish. It readily sends flower spikes above the water in aquaria. It is said to hybridise easily with other Aponogeton species, and some relatives have similar wavy leaves, so check the leaf shape rather than relying on the name. With adequate light and a nutrient-rich substrate it grows without CO2 or much care, making it good for beginners. It prefers slightly acidic water but adapts to higher pH. Cut yellowing or decaying leaves at the base. It is propagated by dividing the tuber or from seed. Plant it in groups in the background or as a solitary specimen. Tubers and potted plants are sold at aquarium shops in Japan.
