Edibles to grow in water!

[veggiechicken]

Next nutty idea - ready?

I've just bought some Ipomoea aquatica aka Water Convolvulus (what a funny word to spell) aka Water Spinach and a million other names.
Permaculture Plants: Water Spinach or Kangkong | Temperate Climate Permaculture

It grows in ponds and in boggy ground.
My thoughts are............can I grow it in a trug/bucket of water or my mini-pond.

If so, what other edibles could I grow in a bucket?
Could one have a pond full of edibles - and I don't mean fish!

I've grown watercress in a container of soil under the GH downpipe, to keep it damp - that's a start!

I filled in the pond relocated the fish to make my veg beds but i've still got the tin bath my friend gave me so i could give things a try. like the watercress I've not got around to sowing.

Won't the water stink?

Ideally, I guess, you'd keep topping it up with fresh water?

I seem to remember that a bundle of barley straw and lavender keeps water sweet....can't remember where I know that from though!

Was told by my neighbor that kept Koi Carp that he put a bundle of barley straw in his pond to keep the water from going green with algae, apparently it kills it but doesn't affect the fish.

Other aquatic edibles are duck potato, chinese water chestnut (Eleocharis dulcis),
The other water chestnut (Trapa natans)and bullrush root

I knew you'd know, Jay-ell
Have you grown any?

[Jay-ell]

No but I done a bit of research because of the bath. Unfortunately cant find anywhere selling the Chinese water chestnuts though.

Rice if you can find any seeds?
