Notes: Samolus valerandi is anamphibious plant with leaf rosettes consisting of 7-14leaves. The leaves are light green, oval and broadened,10 cm long and 3-4 cm wide with a narrow base. Samolusvalerandi is very ornamental as a foreground plant,in shallow aquariua, or alternatively, as a swamp plantin terraria. Samolus valerandi benefits from anutrient rich substrate - though it is not conditionalfor good growth - but it requires high light to thrivewell. Samolus valerandi is an easy beginner'splant though one has to be patient with the emergent form- the one sold in the stores - because it may take awhile for the plant to adapt to the aquatic environment.
Fortunately my aquarium is suited for this plant with a thick pure Flourite substrate, CO2, and over 4WPG of light. As well, I believe the specimens I picked up are already adapted to aquarium as they had been at my LFS for several weeks and continued to look quite healthy over that time. Now to just wait and see...
