San Pedro Cactus (Echinopsis pachanoi)

A legendary columnar cactus treasured for its rapid growth, striking green ribs, and towering presence. Available as healthy rooted plants or fresh cuttings ranging from 6 inches to 35 inches tall, San Pedro is a fast-growing centerpiece for landscapes and collections alike.

San Pedro is one of the fastest-growing columnar cacti, often reaching 12–18 inches of new growth per year. Outdoors, mature plants can soar up to 20 feet tall. Its tall ribbed stems and spectacular, fragrant white flowers make it a striking choice for both desert landscapes and container growing.

Cutting vs Rooted

Cuttings are fresh, unrooted sections taken from mature San Pedro plants. They arrive calloused and need time to rest in a dry, shaded spot for a few weeks before planting in cactus soil. Avoid watering during this period to prevent rot. Rooted plants already have established root systems and can be potted immediately. Once planted, wait about a week before lightly watering to help them settle in.

After Arrival

Carefully unpack your cactus right away. If it’s a cutting, let it rest before planting. If it’s rooted, pot it up and allow several days before the first light watering.

Transplant Tips

Use a gritty, fast-draining soil mix with pumice, perlite, or coarse sand. Always plant in pots with drainage holes or directly into a well-draining landscape bed. Water deeply but only when the soil is completely dry.
