Echinopsis spachiana, the Golden Torch Cactus, blooming. Shot through timelapse photography. The golden torch cactus blooms at night, usually during the twilight hours, and it's blooms last only one day. It typically blooms one night a year. Blooms ripen and open over about three hours time and the effect is so quick and violent for the plant, you will see the flowers twitching and shaking to begin the process.
