Generally familiar as San Pedro. Grows in rocky, well-drained soil along the full length of the Andes Mountains, stretching from Argentina to Ecuador. A high altitude native (6000-9000 feet), this plant thrives in cold climates down to 15 degrees F. We love Echinopsis pachanoi for its ornamental uses in the garden. As a sturdy vertical design element it’s second to none, able to fit into tight spaces and growing 10-20 feet tall. A single stem will pup and branch, creating a staggered clump of fast-growing spires with a well-balanced form. Unlike other columnar cactus, San Pedro is relatively unspined, increasing its usefulness around patios and walkways, in pots and even indoors in a sunny spot.
