it is a new language. you'll soon speak it.
I had a look at the photos you've posted and seen all hardy deciduous shrubs, these will lose their leaves in winter but won't die. prune/move or leave them alone in the winter.
Plus one herbaceous perennial which will be hardy, the one with yellow flowers. that can be split up in autumn or spring and the bits replanted to make a bigger patch.
there are a lot of things on youtube demonstrating how it's done plus loads of recordings of assorted TV gardening programmes. there was a series which may havebeen called 'how to be a gardener' or sometging similar with Alan Titchmarsh. He got right down to the basics in that programme and shoed how to do everything.
worth a watch.
