Aponogeton Undulatus

This is probably the best suited Aponogeton species for the aquarium. It generally does not require a rest period like most species, is quite hardy, and propagates vegetatively--the only species to do so. Inflorescences are produced, but instead of flowers, plantlets develop from the nodes, similar to Echinodorus plants; these can be separated in about 2-6 weeks once the tuber and leaves are formed, though they frequently separate on their own. The tubers can be planted in the substrate to form new plants. The second photo below illustrates the inflorescence with plantlets.The tuber is up to 2.5cm/1 inch in length; the medium-green ribbon-like leaves grow up to 35cm/14 inches long and have undulate margins. Floating leaves are rare but when produced can be up to 90cm/35 inches in total length.
