The bougainvillea blossoms are white, of course. The image was taken with Camera+ on the iPhone and then Gungetastic manipulated using various textures.
The top of a 27 year old Saguaro Cactus that was only one foot tall when I moved here; it obviously didn't like living along the foggy Monterey Coast. The Saguaro proudly stands at 3 feet tall now. I have no idea how many apps this went through until I ended up with this. It's time to start thinking about removing the Cactus from the pot and putting it into the ground where it will live indefinitely.
