We have a few of these left from a shipment that we imported for large public aquarium in the USA. no dissapointments.
Yet another plant from Madagascar, Aponogeton biovinianus Has wide heavily puckered leaves that look like a piece of kelly green seersucker. While some sources report that this is one of the more difficult Aponogetons, other people seem to have very good luck with it. What is clear is that this is another plant that requires very clean water as well as a rich substrate. Unfortunately, this plant has not been successfully propagated at this time, so supplies are imported from the wild, with the result being that they are somewhat rare and expensive.
