The San Pedro cactus, or Trichocereus Pachanoi (Echinopsis Pachanoi), is native to the slopes of the Andean mountains primarily in Peru and Ecuador. In the wild, it is grown for its beautiful emerald green columnar form and fragrant dinner plate sized white flowers. The flowers bloom at night and are pollinated by bats, moths and bees before the flower close in the morning.
As is nature, actual plant may vary from the photo!
