For just one night each year cereus, the collective name for a group of flower-producing cacti, open up to reveal their pretty white blossoms. Usually taking place in either May or June, this fleeting spectacle is best seen at Arizona’s botanical garden of Tohono Chul. Here more than 300 of these night-blooming plants are monitored around the clock in the hope that this phenomena is captured as it unfolds.
