Aponogeton longiplumulosus from Madagascar has large, fluted leaves (35-60 cm long), making it a superb plant which may be perfect for large aquariums (the entire plant turns into 25-40 cm wide). It is quite undemanding, with no special demands on water quality. It also blooms regularly, making it a lovely addition to any big open aquarium. However, it stops developing at regular periods, but begins once more after some weeks of dormancy.
