Aponogeton
These very beautiful plants are by no means easy to keep in an aquarium, as they
have to pass through a "wintering" period lasting a few months, at a temperature
of around 15°C. Their bulbous rhizome, with no leaves, must be kept in a separate
tank in shallow water. After wintering, the water level and temperature are increased.
The aponogetons like strong lighting and moderately hard water. Sexual reproduction
with flowers is possible in an aquarium. Vegetative multiplication occurs if the
rhizome is divided, and buried once leaves and roots have appeared.
Aponogeton crispus
A. crispus grows quite quickly. Like the other species of this genus, it looks
best if it is grown as a single specimen, highlighted against other plants. Size:
40-50 cm.
Aponogeton ulvaceus
With its wavy, translucid leaves this specimen is considered to be one of the
prettiest aquarium plants. Size: 40-50 cm.
Aponogeton madagascariensis
The leaves of the Madagascar laceleaf consist of veins, which give it a striking
appearance but also make it especially vulnerable to invasions by filamentous algae.
It is often sold under the names Aponogeton fenestralis or Aponogeton henkelianus,
but has a reputation for being difficult to cultivate. Size: 40-50 cm.
