STRAWBERRY CACTUS FLOWERS.
A few years ago I was photographing on a ranch in Texas for several months. It hadn't rained there for about 8 months, but for many weeks the strawberry cacti were covered in buds that wouldn't open. Then, one day it rained 4 inches, and almost overnight the desert came alive. Blossoms were everywhere for a few days, and the effect was simply mind-blowing.
