Water lettuce growing very well and reproducing very fast, Hornwort went from a small patch to covering the whole pond in a matter of few weeks, don't mind it to be honest. Bog seems to be working well, plants are growing, fish are happy and the lily's about to rise to the surface which I am very happy about and a great surprise.
Though I don't have many plants on this margin, most of these taller grasses simply do not like shade it seems. They'll grow but they end up floppy. Thinking I might add some marginal Carex grasses, I have seen people talk about it here and I use it extensively in the garden because nothing beats an evergreen like that, but I have not tried it on margins. I've got Carex riparia in bog but it's in the name.
Iris's a bit disappointing, but that may be cause many of these margins are just big rocks and so I guess the roots don't have much to hold on to?
