Submerged, pond plants that are hardy in winter?

[Pondgal]

Would you recommend any plants for oxygenation that are perennials and sustainable through winter months of cold temperatures and some ice and snow please? We have a 13,000 gallon pond in Appalachian Mountains of NC. Thanks in advance!

Anacharis as long as you keep it under the freeze level by putting in pots or tubs on bottom of pond w/roots in soil. Fish might pull them up tho and like to nibble on them. It grows here in wild ponds and we can go out and pick them out for free. Might be in your area also in lakes or slow river/creek areas.

I stuck some anacharis in my lotus tub that survived winter here. Water continually circulates from my bog to the tub and the pond. Doesn't seem to interest the goldfish much though, I see them nibbling on algae most of the time.
Welcome.

My anacharis does really well. I’m in NW Louisiana, so our winters are mild, but water temps do still drop into the 40’s at the coldest. If your pond has any depth at all, it should do well.

Is your pond lined or natural?

Hornwort easily survives winter even on the lower shelves. at least in zone 7 where i am

Both survive here , even in my freeze almost solid shallow water collection areas. The deck pond is shallow and it can freeze solid, no fish. The plants come back every spring.
