Flowering stand of San Pedro cacti (Trichocereus pachanoi)
To me the main draw of the San Pedro cactus (Trichocereus pachanoi (syn. Echinopsis pachanoi)), a fast-growing columnar cactus native to the Andes Mountains of Ecuador and Peru, has always been that it is unsurpassed as a grafting stock. In my opinion it is the perfect rootstock for grafted peyote and similar cacti, as it ensures fast growth and is long-lived.
That being said a towering stand of San Pedro cacti is spectacular in its own right, and the large, beautiful, fragrant flowers are nothing less than awesome!

I took these pictures last summer but will not disclose the exact location. After peyote (Lophophora williamsii) the San Pedro cactus is one of the most mescaline rich species of cacti and is widely sought after for recreational use - I’m sure the grower of these plants will be quite angry if they are maimed and disfigured by “I, me, mine” types looking for a quick trip. If you are so inclined, grow your own plants.

As I said, San Pedro flowers are nothing less than awesome :-)
