Cactus Flower Wallpaper is a beautiful flower collection that I found while browsing on the web. I've combined the flowers with vibrant backgrounds. Awesome flowers with sharp needles. Right-click on the wallpaper of your choice and "save picture as/set background". Wallpaper dimensions are 1200 x 750 pixels. For best results, set your wallpaper preferences so that the wallpaper fills the whole screen.
