When I was a kid we used to press flowers and leaves in books. Every once in a while I still find a fern or a daisy in an old book. You can get the same feeling without the mildew!
It's nice to see cupcakes without any frosting on them. The surface of the cake is perfect for the crumbly soil effect around the sprouts. Dare I say it, they almost look healthy with just a little fondant sprout and lack of buttercream.
