Cactus | Plants

San Pedro, scientifically known as Echinopsis pachanoi, is a fast-growing, columnar cactus native to the Andes Mountains of South America. Its vibrant green stems, adorned with small, blunt spines, can grow up to 10-20 feet tall, making it a beautiful addition to both large and small gardens. San Pedro is particularly known for its impressive white, trumpet-shaped flowers that bloom at night, often filling the garden with their delicate fragrance. Its rapid growth and low-maintenance needs make it a favorite for those looking to add height and texture to their Arizona landscapes.

Type of Light: Full Sun to Partial Shade
San Pedro thrives in full sun but can tolerate some afternoon shade, especially during Arizona’s intense summer heat. For best results, plant it in a location where it receives ample morning sunlight and partial shade in the hottest part of the day.

Watering: Moderate Water Requirement
Though drought-tolerant, San Pedro requires more water than many desert cacti. During the summer months, water every 1-2 weeks, allowing the soil to dry out completely between waterings. In cooler months, reduce watering to once every 3-4 weeks, ensuring the plant is not overwatered.

Companion Planting:
San Pedro pairs well with other columnar cacti like Mexican Fencepost or Organ Pipe Cactus, adding vertical interest to your garden. It also works beautifully alongside Red Yucca and Golden Barrel Cactus, which provide color and texture contrast. For added pollinator attraction, plant it with Desert Marigold or Verbena to bring bright flowers to your landscape. These combinations will create a balanced, vibrant desert garden that thrives in Arizona’s climate.
