Organ Pipe Cactus (Stenocereus thurberi)

Organ Pipe Cactus

So I am starting out with one stem and a height of 2 feet when planted. As the plant matures it will not branch out, but will extend from the tip, and each season's growth will be marked by a constriction of the stem. Flowering annually, with large white blooms that open at night and close the next day. The flowers are pollinated mainly by bats and so I will plant this in an area where there would not be much human traffic.
