I first saw sweet potato vine planted in a container water
garden in a magazine. They placed at the edge and it
trailed over.
There are all sorts of pretty colours available now in the
nursery.
I haven't tried it yet in the pond, until I tried it on the island.
I was going to train it up some kind of artsy trellis that I
was going to put in the middle of the island.
I might find another corner on the deck for a container water garden
and
try it again....
