Just how tall and wide does the Cereus Hildmannianus or Queen of the Night grow? Ours is over 15 feet tall and 6+ feet wide now!
According to this source, http://sunnygardens.com/garden_plants/cereus/cereus_0610.php , yours appears to be a fully grown specimen.
Thank you for your info. I'm very proud of my Cereus hildmanianus. I'm 69 yrs. old and my plant is an offspring of a 4" specimen I presented to my Dad when I was 13 yrs. old and returned from a trip to San Francisco. It was purchased at the Cliff House Resturant. Dad's plant reached every bit as high or higher and was the focal point of his front yard. Nursery personnel would come to his door to inquire about it. It's blooms, like mine, were a startling sight in the night. Thank you again, Mickey C.
