Senita Cactus (Lophocereus schottii) – A Unique Desert Native for Phoenix Landscapes

The Senita Cactus, scientifically known as Lophocereus schottii, is a distinctive columnar cactus native to the Sonoran Desert, thriving in both Mexico and the southern United States. This upright cactus is perfect for adding a shaggy, sculptural element to Phoenix Valley gardens with its striking appearance and drought-tolerant nature.

Distinctive Shaggy Appearance and Growth

The Senita Cactus typically grows between 6 to 15 feet in height, forming multiple branching stems that grow both upward and slightly outward, creating a sprawling, vertical structure. Its stems are ribbed and covered in small spines, but its most eye-catching feature is the long, white hairs near the top of the stems, giving it a woolly, textured look that sets it apart from other cacti.

Night-Blooming Flowers and Edible Fruits

The Senita Cactus blooms with white or pale pink flowers, which open at night and close by morning—an adaptation to attract nighttime pollinators like moths and bats. These blooms are followed by edible red fruits, adding even more interest to this plant. The flowers and fruit enhance its biodiversity appeal, making it a valuable addition to desert gardens that attract wildlife.

Ideal for Phoenix Xeriscaping

This cactus is perfectly suited for the hot, arid climate of the Phoenix Valley. It thrives in full sun and requires well-draining soil to prevent root rot. Being a drought-tolerant species, it only needs occasional watering, making it an excellent choice for xeriscaping and low-water gardens in the area. However, it is not frost-tolerant, so in colder parts of the valley, it may need frost protection during the winter months.

Why Choose the Senita Cactus?

  • Distinctive shaggy appearance adds unique texture and vertical interest to any garden
  • Low-maintenance and perfect for drought-tolerant landscapes
  • Night-blooming flowers attract nighttime pollinators, adding an ecological benefit to your garden
  • Thrives in the Phoenix Valley’s sunny, dry climate, making it ideal for desert landscaping
  • Versatile enough for use in rock gardens, accent planting, or as a focal point in desert gardens

Perfect for Phoenix Gardeners

Whether you’re looking to create a drought-tolerant landscape or add a sculptural element to your garden, the Senita Cactus offers an exotic, visually interesting option. Its woolly texture, nocturnal blooms, and low-maintenance needs make it a favorite among gardeners in the Phoenix Valley.

  • Watering Amount: Provide 2-3 inches of water per session for deep watering

When is the Plant Established?

  • Timeframe: Senita is considered established after 4-6 months when the roots have spread into the surrounding soil

Watering Once Established:

  • Winter: Water every 6-8 weeks during the cooler months, depending on rainfall.

Drip Irrigation Setup:

  • Placement of Emitters: Place the drip emitters 18-24 inches away from the base of the cactus for deep watering
