Rainbow Roses Are for Real
Invented by Peter van der Werken, the owner of a flower company close to Den Bosch, Holland, rainbow roses look like they have been seriously modified in programs like Adobe Photoshop. But, they are actually the result of careful flower engineering. Dye is inserted into the stem of the rose as its growing, and the petals simply absorb it. Sounds easy enough, but its a very difficult process.
Sadly, you can't buy rainbow rose bushes, only cut, or dried flowers. And even those come at a price meant to keep most of us away. Five cut rainbow roses sell for $55 and two dozens cost up to $325. But it you are going to spend a small fortune on a flower, why not buy a freeze-dried rainbow rose that will last for years.
