Well my younger cousin is getting married soon and recently asked me about blue flowers. Yes there are actullay some flowers in nature that are blue. I found a good site that had a big list of blue flowers. Go to http://www.rose-gardening-made-easy.com/types-of-blue-flowers.html to see some great pictures of some blue flowers. It is true though that some flowers that are called blue are actually a blue purple color, but not true for all of them. I think one of my favorite blue flowers is the Blue Mist Spirea, which I had as my plant pick of the month for September last year.
