Trichocereus Pachanoi (San Pedro Cactus) Seeds BULK


SKU: N/A Category:


Trichocereus Pachanoi is perhaps the most famous of the trichocereus species. This easy-to-grow, ornamental, columnar cactus is popular for a variety of reasons. San Pedro cactus is a sacred symbol among the various peoples of its native habitat, which stretches from the Andes of Peru to Bolivia to Ecuador. A common landscaping cactus, trichocereus pachanoi is also tolerant of a wide variety of conditions and can handle more water and fertilization than most cacti, making it a good cactus species for beginners. Trichocereus pachanoi’s small spines also make San Pedro Cactus easier to handle for those who are not experienced with dealing with sharp spines or those who have curious kids or pets that may be injured by larger spines. Additionally, San Pedro cactus is a rapid grower, making it a favorite grafting stock for speeding up the progress of slower-growing cacti such as astrophytum and ariocarpus. Under ideal conditions, San Pedr cactus can grow up to 18 inches per year and will readily shoot off new pups (branches). Frost hardy to about 26 degrees Fahrenheit, San Pedo cacti can be raised outdoors all year in Zone 9 or warmer. Otherwise, it should be kept in medium to large pots that can be moved inside during the winter months. Trichocereus pachanoi can be watered frequently during the summer months, sometimes as often as every two days if the top inch or two of the soil is dry. During the winter, your San Pedro cactus should be slowly acclimated to cool, dry, dark conditions to avoid stretching that could damage the aesthetics and structural integrity of the plant. When breaking dormancy in the spring, a reverse process of slowly introducing the factors necessary for growth may be beneficial for the same reason. For optimal skin color, trichocereus pachanoi should be kept in partial rather than full sun and the soil should be well-draining and rich in organic nutrients and minerals. Pachanoi blooms are large, white and have a strong, pleasant perfume.

Trichocereus pachanoi grown from seeds typically have larger spines than the so-caled PC (predomiant cultivar) clone of trichocereus pachanoi.  The PC clone is usually reproduced by cuttings, so it maintains it’s small spine feature.  The PC pachanoi has been in cultivation in this country for many decades and has become easy to recognize, but it is not how trichocereus pachanoi appears in nature. Wild trichocereus pachanoi typically resemble more of what people expect of trichocereus peruvianus. The spines tend to be brown and longer. There is also more variety as cross pollination increases the gene pool. So when growing trichocereus pachanoi from seed, these types of variations are to be expected.
