Queen of the Night blooms: The single night life of a desert flower
The cacti Peniocereus greggii, also known as the Queen of the Night, unfurled its petals Monday night for its annual bloom. The one-night spectacle drew crowds of admirers to Tohono Chul Gardens to get a glimpse of the night-blooming cereus before it faded with the dawn, not to return for another year.​​​​​​​
