The Trigonia Cactus, scientifically known as Trichocereus Spachianus, is a tall, columnar cactus that adds beauty and height to any desert landscape. With its ribbed green stems and clusters of short spines, the Trigonia Cactus is a striking, fast-growing plant that can reach up to 10 feet in height. In the warmer months, it produces large, white, night-blooming flowers that attract pollinators such as moths and bats. This cactus is perfect for Arizona landscapes due to its low water needs and ability to thrive in hot, dry environments, making it an ideal choice for xeriscaping or as a focal point in rock gardens.

Type of Light: Full Sun
Trigonia Cactus thrives in full sun, which helps it grow tall and produce its beautiful flowers. Be sure to plant it in a location where it will receive direct sunlight for most of the day to ensure optimal growth and health.

Watering: Low Water Requirement
This cactus is highly drought-tolerant and requires minimal watering. During the hot Arizona summer months, water once every 2-3 weeks, allowing the soil to dry completely between waterings. In the cooler months, reduce watering to once every 4-6 weeks.

Companion Planting:
Pair Trigonia Cactus with other desert plants like Golden Barrel Cactus, Agave Parryi, or Mexican Fencepost for a dramatic vertical display. To add color and attract pollinators, plant alongside Desert Marigold or Penstemon, which offer bright, contrasting flowers. These companion plants will create a visually appealing, low-maintenance desert garden that thrives in the Arizona heat.
