The number of chromosomes is 2n = 26, 32, 48 or 52.

Aquaristics

Like a whole range of water ears ( Aponogeton ), this type of plant is also offered in specialist shops for planting aquariums . However, this type of water ear is already one of the demanding aquarium plants , it requires a rest period in which the tuber can regenerate itself for longer maintenance. The plant's light requirement is medium to high. It needs water temperatures between 25 and 32 degrees Celsius. It is suitable for planting the background and central zone in the aquarium and can also be used as a specimen plant . Due to its size, the aquarium in which it is maintained should hold at least 150 liters of water. Carbon dioxide fertilization is recommended.
