Iris in pot on shallow pond shelf?
Hi everyone. I have recently put in a pond, which I hope will become a wildlife haven. It has an area of very shallow shelf, just a few cm below the water line. Would it be reasonable to put some potted irises (aquatic compost etc) onto these shelves?! If so, what pots could I use that would look nice, and cope with having their bottoms in the water? I may end up just putting a few pebbles on the shelf with home hornwort etc for tadpoles if the irises don't work, but the pond does have another beachy area so I would like to try something different!
