Ludwigia
Ludwigs thrive on light, iron, and fairly rich soils. Cuttings are taken by lopping
off a stalk under the adventitious roots. Another option is to cut off the top of
the plant, which avoids the loss of any of the lower leaves. Size: 30 cm.
Ludwigia ascendens
The totally aquatic large-petaled ludwig can sometimes appear above the surface.
It tolerates a wide range of hardness and a pH of around 7. It is especially recommended
for beginners.
Ludwigia alternifolia
As its name indicates, the leaves of the alternate leaf ludwig are arranged alternately
along the stem, and not directly opposite each other. It prefers soft, acid water.
Size: 30 cm.
Ludwigia brevipes
A fairly resistant plant, the false lusimakhos tolerates hard, alkaline water
and temperatures slightly below 20°C. It can therefore be used in a temperate aquarium.
Size: 30 cm.
Ludwigia repens
The rampant ludwig is found in both a green variety and a reddish variety. Both
require good lighting but are considered hardy. Size: 30 cm.
