Do you mean perennials? My ducks tend to leave creeping phlox alone as well as the hydrangea, the rose bush seems unscathed as well. A nice bonus for the rose bush is that ducks will eat all the japanese beetles that tend to decimate the leaves. I also haven't had any problems with potted annuals like petunias, vincas, and others along those lines.
My ducks are now free ranging all day so the tendency for them to eradicate all greenery is greatly reduced. Only the water chestnut has this problem.
