I have had very good luck with water hyacinth. I have a 6 foot diameter floating ring made of PVC pipe with foam pipe insulation over that. Last winter I took 3 plants a friend had in his garden pond because they were just going to freeze anyway. I overwintered them in a bucket of water in a bright heated room and after last frost this year in early June, I put them in the ring. They looked pretty lonely in the ring, 3 plants and a 6 foot ring but this is a picture from mid July.

The ring is tethered to the bottom to keep it from drifting all about but it seems to attract floating duckweed which collects behind it. The good thing is it makes netting out duckweed easier.

I will remove some of the hyacinth soon to get the biomass out of the system and leave room for it to continue to grow until it gets cold. Then I will rescue 3 lucky plants for next summer and compost the rest.
