I want to make a little barrel pond someday, too. One I could put on the porch. I don't know what I would keep in it, probably end up being a giant cat water bowl.
There are some lovely varieties of tiny water lilies, which Iād like to try, and watercress is supposedly very easy and a nice tasty salad crop. (The question of how I would keep my hypothetical future ducks out of it is an interesting one.)
@Flick š¬š§ @38bc42fd arrowhead and cape pondweed are edible and good in even tiny ponds
Ta, added then to my plant list.
