A columnar and tall San Pedro cactus tops the lists of low-maintenance plants and will adorn your garden with its pretty pillar-like structure.
San Pedro cactus is also known as Echinopsis pachanoi or Trichocereus pachanoi. It grows in South America and loves hot weather.
These cacti tend to reach 20 feet (6 meters), so they need plenty of space. Trichocereus pachanoi produces white flowers and some edible fruits in summer, so you’re in for the harvest!
