Nymphaea lotus
("zenkeri") - or the Tiger Lotus - is recognised to be
among the most graceful aquarium plants. It is a quite variable species and
the leaf colour may vary from bright green over red-brown to red-violet. It
is without comparison the most suitable Nymphaea species for
aquarium purposes because it sets numerous water leaves before floating
leaves are produced. When floating leaves are produced the plant easily sets
flowers, too. A nice odour escapes from the flower which, however, only opens
during night-time. If, on the other hand, floating leaves are unwanted due to
the strong light competition, newly formed floating leaves and longer roots
may be removed. The plant thereafter begins to produce water leaves. Nymphaea
lotus ("zenkeri") is an unpretentious plant though a nutrient
rich substrate is required to sustain optimal growth.
