Why is it hard to find this plant in the uk
Its high demands and its limited usability in the aquarium are probably the reason why this Ludwigia is not as popular as other species of the genus.
Ludwigia inclinata is enormously light-hungry. If provided with highly intensive light, and in addtion with a good supply of liquid fertiliser, it grows very fast, 30 to 40 cm in just one week.
Its very fast growth makes L. inclinata a lesser choice for sophisticated aquarium layouts.
