If you're a regular visitor on my blog then you've probably realized my super-Likes for tangible rainbows, (see "Marshmallow Fondants, Rainbows to go and Bleu Blanc Rouge). I just have to share these multi-colored flowers. It's not your usual bouquet of roses, they're way cooler! It was two Dutch companies, River Flowers and F.J Zandbergen, who successfully grew rainbow roses in 2004. The idea is to split the stem into several channels and dip each one in a different colored water.
