C. Poppies are annuals. My Verbena B falls all over the place, even in planted sandy soil. With lots of rain and wind I would imagine they would be a pain. I've not tried oriental poppies.
For this question, I would highly recommend Piet Udolf's book Dream Plants for the Natural Garden. He lists perennials under various classifications from "Tough" meaning hardy and reliable to "Troublesome". One of his pet hates seems to be plants that need staking, so these don't generally make it into the "Tough" section.
Shrubby upright Salvias (more bush than perennials, but hey) - microphyllalike the Lips series, Bumble, the So Cool series, Trelissick, Melen etc. I wouldn't recommend Blue Note, Nachtvlinder or those kind of sprawling types.
Penstemons are good here, but crocosmia and Rozanne have metal rings around them. I never feed the ground but do pile on lots of home made compost in the winter.
Gardening on the wild, windy west side of Dartmoor.
I've had to stake up our Crocosmia for the last two years. They now reach the top of our six foot high fence. At the moment they are leaning precariously to one side because of the winds despite being staked😕
