Neobuxbaumia euphorbioides

A Neobuxbaumia euphorbioides in my collection

     Neobuxbaumia is a genus of a half dozen or so columnar cacti from Mexico. Some are solitary columns and others branch producing a familar candelabra shape. Flowers are nocturnal and pink to white.
     Neobuxbaumia euphorbioides is a large columnar from the states of Tamaulipas, San Luis Potosi and Vera Cruz, Mexico. I am assuming the name came from it's uncanny resemblance to some Euphorbias. One of it's tell tale features is the way the ribs tend to cut in here and there. Flowers are ruffled pink with a pale yellow center and the plant can reportedly flower at about 4 foot in height. I don't know how long they take to grow that tall, I couldn't find much other information on the plant. I can't be sure if it's solitary or perhaps branches at the base.
     This came from Bachs Cactus Nursery and is about ten inches tall. I'll find a suitable place for it in the yard. Geoff Stein, a fellow member of the Davesgarden.com gardening forums, allows me to use his pictures on the site. Thanks Geoff :-) Also check out a gallery of some of his other pictures in the Photo Galleries/Friends section. Below is a picture of a very old stand of the plant at the Huntington Botanical Gardens. It looks to me like the plant must branch at the base.
