Samaipata Torch Cactus Cleistocactus samaipatanus
ABOUT
The Cleistocactus samaipatanus, also known as the Bolivian Torch Cactus, boasts a distinct and striking appearance. This cactus is characterized by its columnar growth habit, meaning it tends to grow in a tall, slender shape, often resembling a torch, which is where its common name derives from. The surface of the plant is covered in a dense array of white to silver spines that encase the green to blue-green colored flesh beneath. Over time, this cacti can develop numerous branches that emerge from the base or along the sides, giving it a somewhat bushy appearance. The unique spination of the Bolivian Torch Cactus, with spines arranged in clusters, specifically in groups called areoles, creates a shimmering halo effect that adds to its beauty and appeal. A mature plant will sometimes produce flowers that emerge from the sides of the stem, just above the spines. These flowers tend to be tubular in shape, and can range in color, often displaying hues of red, pink or orange. The blooms of the Bolivian Torch Cactus usually open during the day and close at night. Overall, the Cleistocactus samaipatanus is a visually striking plant that can add interest and an exotic touch to any collection of cacti or succulents, whether grown indoors or in an outdoor setting that replicates its native high-altitude environment.

- Water
When watering Bolivian Torch Cactus, it's important to be cautious of over-watering. During its growing season in spring and summer, water once the top inch of soil feels dry, approximately every 7 to 10 days, with enough water until it starts to run through the drainage holes, using about 8-16 ounces depending on the size of the pot. In fall and winter, reduce watering to once a month, or less if the soil is still moist, to prevent root rot, providing only 4-8 ounces of water each time. Always use a well-draining soil mix and pots with good drainage to avoid water retention around the roots.
- Light
Bolivian Torch Cactus thrives in bright, direct sunlight and should be placed in a location that receives several hours a day of this lighting condition, like a south or west-facing window. Ensure that it receives at least 6 hours of direct sunlight daily for optimum growth and flowering. However, be cautious of extreme sunlight in hot climates that could scorch the cactus, so some afternoon shade might be beneficial in these cases.
- Temperature
The Bolivian Torch Cactus prefers a warm environment and can tolerate temperatures up to 100 degrees Fahrenheit, but it should not be exposed to temperatures below 50 degrees Fahrenheit for prolonged periods. An ideal temperature range for healthy growth is between 70 and 90 degrees Fahrenheit. It is not frost-hardy, so it must be kept indoors or in a greenhouse in regions that experience cold winters.
- Pruning
Bolivian Torch Cactus typically does not require regular pruning. Pruning should be carried out to remove any dead or damaged parts of the cactus for aesthetic purposes and to promote healthy growth. The best time to prune is in the spring, before the active growth season begins. Always use clean, sharp tools to make cuts to minimize any damage or stress to the plant.
- Cleaning
As needed
- Soil
The ideal soil mix for Bolivian Torch cactus should be well-draining and gritty, composed of a combination of potting soil, coarse sand, and perlite or pumice at a ratio of 1:1:1. The preferred soil pH range for this cactus is slightly acidic to neutral, around 6.0 to 7.5.
- Repotting
Bolivian Torch cactus should be repotted every 2 to 3 years or when it has outgrown its current pot. It is best to repot during the spring or early summer when the cactus is actively growing.
- Humidity & Misting
Bolivian Torch cactus thrives in low to moderate humidity levels similar to arid environments. It is well-suited to typical indoor humidity levels, but high humidity should be avoided.
- Suitable locations
Indoor
Place in bright, indirect light and maintain dry conditions.
Outdoor
Full sun to partial shade, shelter from excessive moisture.
Hardiness zone
9-11 USDA.
- Life cycle
The Tarabuco torch cactus (Cleistocactus samaipatanus) begins life as a small, round seed that germinates in well-draining soil with warmth and minimal moisture. Once sprouted, it develops into a seedling with tiny spines and begins photosynthesis. As it matures, it grows upwards, gradually forming a slender, columnar stem covered in dense spines, which can reach up to 2 meters in height. The cactus eventually produces tubular, red to pink flowers from the areoles along the sides of the stem, typically during spring or summer. These flowers are pollinated by birds, bees, or bats, leading to the development of small, berry-like fruits that contain seeds. Over many years, the plant may produce offsets around its base, creating a clump of stems, and continues its cycle by dispersing seeds for the next generation.

Propogation time
Spring-Early Summer
Cleistocactus samaipatanus, commonly known as the Bolivian Torch Cactus, is best propagated through stem cuttings. This method is typically done during the warmer months of spring and summer when the plant’s growth is most active. To propagate, a healthy stem is selected and cut with a sharp, sterilized knife. The cut section should be about 4 to 6 inches long (approx. 10 to 15 cm). It is important to let the cutting dry and callous over for a period of about a week before planting to prevent rot. The calloused end is then placed in well-draining cactus mix, and the soil is kept slightly moist until roots develop. This can take several weeks, after which the cutting can be treated as an established plant.
