Currently around 3 feet tall. This columnar cactus is native to Mexico where it's sometimes used as a literal fence. Who wants a boring ole fence when you can have a cactus fence!? Clean gorgeous white margins are what makes this one of our favorites. It blooms in Spring in a variety of colors (white, pink, red range). It can grow 8-12 ft. tall. Give it full sun and well draining soil. Water when completely dry.
