Huh! the shape of the leaf on the stem you have in close up looks different from the ones in the background. Its leaves are broader. I did not know that rotundifola can change its leaf shape like that. Very nice in any case. How often do you have to trim?Thanks guys
kakkoi - There are some bolbitis rhizomes, just waiting for them to sprout more leaves
Bunbuku - That is Rotala sp. Green
Tex Gal - Weeping moss is much slower growing and 'weeps', while Xmas moss grows outwards.
