Flowering wall plants that are safe for ponds

Fish safe Climbing wall plants Looking for a bit of advice regarding flowering wall plants that are safe for ponds if the leaves or petals were to go in. The pond is almost finished but behind is a not very nice concrete wall/fence. It used to be all covered in ivy which I’ve removed (one panel left) and we have new lattice panels coming to cover the wall but looking for suggestions for fish safe wall climbing plants similar to a wisteria, jasmine or clematis etc. Any recommendations? Or any to avoid? Thanks See less
