Blooming Stamps

From the Dutch, of course:

Despite the photograph, the stamps won’t bloom en route, but rather are embedded in the stamp beneath a thin layer of plastic. The lucky recipient simply peels back the plastic, plants the stamp and seeds, and watches them bloom. We love the fact that the poetic design is issued through such a civic entity, and the concept of delivering something cheery (and natural) through such an everyday object.

And from Sweden: talking paper.
