San Pedro Cactus (Wavy/Creste Variation)
Echinopsis pachanoi (syn. Trichocereus pachanoi)
The image shows a columnar cactus with a distinct wavy or crested growth pattern, which is a common mutation. The stem is glaucous green to bluish-green and appears spineless or with very small spines, characteristic of San Pedro cactus. The wavy growth creates undulating ridges and valleys along the stem, giving it a unique, somewhat melted appearance.

San Pedro cacti thrive in full sun to partial shade, preferring well-draining soil (like a cactus mix). Water deeply but infrequently, allowing the soil to dry out completely between waterings, especially in cooler months. They are relatively cold hardy for a cactus but should be protected from freezing temperatures. Fertilize sparingly during the growing season.
