This looks the waxy material produced by planthoppers. They are very active right now. The bads news is that they are not aesthetically pleasing but the good news is that they do not cause serious damage to plants and they are not active for the entire season. As you can see they are not easily controlled by insecticides. You can spray them off with a blast of water. Please see the information we have on them from our website, http://extension.umd.edu/hgic/planthoppers-flowers
