Cycnogeton procerum

Because of its very long leaves floating at the surface, the ribbon plant is best suited to very large aquariums. According to Kasselmann (2010), Cycnogeton procerum grows well in soft to medium-hard, pH-neutral water and nutrient-rich substrate; medium light intensity is sufficient. The leaves can be shortened. Flower and fruit spikes can also appear above the water in the aquarium.¹

The plant can be propagated by rhizome division, but also by sowing (see Clasen 2001²).

Because it is little known in the hobby and also difficult to obtain, but also because it develops very long leaves, the water ribbons plant is hardly ever used in aquascaping. It is most likely to be seen among Dutch and Belgian planted-aquarium keepers (see e.g. www.aquaplantexchange.nl), often under the mistaken name "Glyceria maxima". In tall planted aquariums, the light green, very closely set ribbon-shaped leaves can form an interesting contrast with plants of a different texture and colour. In habit, the water ribbons plant is reminiscent of tall Vallisneria species, but has the advantage that it does not produce long runners, so its growth is easy to control.

In the nature aquarium style, Cycnogeton procerum has apparently not yet been used. This peculiar, grass-like, easy-to-cultivate plant from Australia certainly deserves more attention in aquascaping.
