Echinopsis peruviana, also known as Trichocereus peruvianus, is a striking columnar cactus native to the high-altitude regions of the Andes in Peru. Valued for its rapid growth, blue-green stems, and large nocturnal flowers, this species thrives in well-draining soil and bright sunlight. It is a popular choice among collectors for its resilience and ornamental appeal.

Distinctive Features

• Growth Habit: A tall, columnar cactus that can reach heights of up to 6 metres (20 feet), with multiple branching stems.
• Spines: Light brown to golden spines arranged in clusters along its prominent ribs.
• Flowers: Large, white, fragrant blooms that open at night and attract pollinators such as moths and bats.

Care Tips

• Light: Prefers full sun but can tolerate partial shade.
• Water: Allow soil to dry completely between waterings; drought-tolerant once established.
• Humidity: Thrives in dry conditions; does not require high humidity.
• Media: Well-draining soil mix with sand, perlite, or pumice.

• Can be propagated easily from cuttings, which should be left to callous before planting.
• May produce offsets at the base, leading to a clumping growth habit over time.
