Flowers that don't wilt

We have a "temporary" (not so temporary really, as it has been in its place for years) wall in the living room. The wall and the door are of boring brown paper. As it happens, we went to Ikea last week and found a poppy wall decoration for 12 euros. Now the wall looks a bit less dull and poppies suit our house really well as there are a lot of real poppies growing in the garden (not yet, though).
