Pond plants

I've dug my mum and small pond, roughly 1 metre sq, and wondered what plants I could put in it or around it without swamping it.

Thanks

 

Thanks, its just going to be a small wildlife pond.

 

The problem with most aquatic plants is that by their nature they are pretty invasive and spread wherever they are allowed to.
I'd deffo get some type of submerged oxygenator in there (Hornwort, Elode) to help the wildlife.

And in my pond:
Marsh marigold/Kingcup
Blue Iris Laevigata
Houttuynia Cordata 'Chameleon'
Corkscrew Rush
Saururus Cernus (Lizard's Tail)

have all stayed small and well behaved (so far), all in their own baskets and split evry year or so.

 

Many thanks for the info and links, I'll check them out

 

I just wondered, are any of these submersed or do they all float? I've selected a few but they are all 'floaters' so would like one that sits in a pot at the bottom.
