This plant is called a Cereus plant, or “Queen of the Night”. It only blooms perhaps once a year, ONE NIGHT a year, and usually opens up late at night soon after midnight with my experience. This is the second year it’s bloomed, and it’s really an awesome few hours to see her in all her glory, for in the morning, she closes up, and she is done. There were two blooms that opened up at the same time. It’s truly an honor to be in her presence, because it’s SO easy to miss this beautiful bloom!
