I have had a potted cactus in my backyard for years. This is the first year I completely turned off watering the back. I looked out my window and saw a beautiful white flower. Thinking it was the white rose bush, I walk out to take a look wondering how it possibly bloomed. What I found is this beautiful flower, never has this cactus produced such an exquisite work of art that I had to photograph it using various processes (odd my iPhone 6 displays them differently, my favorite was the monochromatic, but it is not showing that way on my Mac). I love them all.
