This is a Night Blooming Cereus, and as you see by the name, yes, they bloom only at night. The blooming process begins right at dusk and is not completed until about 1 to 2am. These flowers begin too grow in the months of May until about November here in the New Orleans area. As the sun rises, the flower begins to close and die. That individule flower does not bloom again. If I could bottle the scent that is given by this flower during its blooming process, I would do it in a heartbeat. The scent fills the air and resembles a very sweet vanilla scent mixed with an almond oil scent. It’s a beautiful process to watch and photograph, but it makes for a very long night, but well worth it. This is just one of many many photos that I shot of this flower and others that bloomed afterwards.
