This is Cosmos Atrosanguineus or chocolate Cosmos. The flowers smell a bit like chocolate. In this photo the green surroundings of the flower were completely blown out because the flower is so dark. The limitation of a digital camera.. :-( The only thing i did to this photo was adding the dropshadow and the border.
At first I thought I was looking at a Lalique brooch. The petals look so much like glass. This makes for an elegant design, the colors are superb. A real jewel. Well done
