Did you know there are cacti that only flower once a year and that the rare occurrence can last a mere 24 hours? In fact, certain species like Selenicereus grandiflorus only flower once a year at night and wither shortly thereafter.

Two recent posts on reddit by Disguise_ready and SnugNinja captured the rare moments on camera. The two cacti are believed to be a species of night-blooming cereus and some kind of Echinopsis hybrid.
