The Victorians all loved Arts and Crafts, particularly flower pressing. They would carefully pick flowers and then, with great care and delicacy, they would squash them flat. Many different sorts of flowers were used, such as daisies and ... you know, those whiteish ones ... anyway, lots of sorts were used. This sort of thing makes more sense when you remember that they didn't have television, and so had to pointlessly waste their time in other ways.
