This flower opened on our big saguaro cactus out front this morning. Most of the flowers had come and gone in June, but last week we noticed a new flower bud. When I say last of the summer, I mean for this cactus, as there are others in town that will likely have more flowers to come. Maybe even this one will have more, but I doubt it.
Since the cactus is very tall, in order to see inside the flower, I had to take this shot from across the driveway with the telephoto lens. Canon SL1 settings: F8.0, ISO 100, Shutter 1/500 sec., Focal Length 300mm.
