Ground cover for a bog garden

[EauRouge]

I've freed up a bit of space in my garden by getting an allotment so now I've got lots of lovely space to play with . Well, not lots because it's not a very big garden. But anyway.

There is one part of the garden that never really dries out (clay soil, at the bottom of a slope) so I've decided to make it a bog garden. I've put in a little pond and I need something to cover the ground around it and spill over the edge.

Is creeping jenny my only option? I've got tons of it already and find it a little invasive. Will anything else do the job? Some of the gaps around the pond are quite narrow.

TIA :)

My whole garden is an acidic, heavy clay bog

Rather than ground cover, there are lots of really lovely plants that like wet ground. I'm trying:

Candelabra primroses
Rodgersia
Marsh marigolds
Astrantia
Irises (not all like wet ground)

There's also some mints (I think spearmint?), bogbean, ligularia. The RHS website has a section devoted to bog plants as well.

If I lived further south, I might try some pitcher plants too (sarracenia) and if I had more space, is plant a stand of Gunnera- it's MASSIVE.

I love Gunnera too, but one leaf would be bigger than the entire pond

Thanks for the suggestions :) I've got a couple of things you mentioned but no bogbean, and it might be exactly what I'm looking for. I also don't have Astrantia so I might see if I can track some of that down, and some more primulas; there's always space for more primulas.

I picked up some candelabra primroses and rodgersia in morrisons last year! The astrantia will be dormant for a while yet, so may be a while before it appears in garden centres.

The only good thing about my boggy garden is that it lets me grow lots of different primulas

There is a small species of gunnera (magellanica) that I've seen used as ground cover in a damp coastal garden in Scotland. I think it can run a bit wild though.

There's a big plant sale near here every year and one of the nurseries that has a stall is a primula specialist so I'll probably wait until then. I usually let the DDs choose so I'm sure I'll end up with something very bright. I'll probably order the rest online, there's not many pond plant places around here unless you want a bag of elodea.
