I've hung a lot of wallpaper in my time, some would have been floral. But for years we've had paper that was plain with a slight pattern in relief. It just gets painted with emulsion every few years.
Digressing, managing large superstores, we always had DIY & wallpaper and paint departments.
Standing in an aisle in one store talking to the manager of the department, we were approached by a little old lady with three rolls of wallpaper in her trolley.
"Can you tell me how to get this wallpaper on the wall?"
"Well. ideally love, you need a pasting table, see if you can borrow one from a friend.
Then you'll need a bucket, a pasting brush, a wide wallpaper hanging brush, wallpaper scissors, a spounge and some paste."
