River rock spread Out would look odd I agree but I have seen some scapes using it and it’s definitely on my todo list because it looks very natural, river rock with wood especially. you can attached plants with glue to all surfaces it’s great! I previously tried thread but it was too fiddly unless I was using moss. When the plants grow you won’t see glue.
as you can see I have also have ALOT of caves
all my plants are glued to loose rocks so I can move them with ease.(larger rocks have nothing glued to them) Just a few crypts, Vallisneria and rotala are not Obviously Glued.
