Discover the Paper Spine Cactus

The mesmerizing beauty of the Paper Spine Cactus is a sight worth beholding. With its unique look, shape, and growth habit, this cactus is a true wonder of nature. First described by Charles Lamarie in 1868, the Paper Spine Cactus, also known as Tephrocactus articulatus var. papyracanthus, hails from the western regions of Argentina, specifically the lower slopes of the Andes mountain range.

A Closer Look

The Paper Spine Cactus, also referred to as the Spruce Cactus, is a fascinating plant. Its pine cone-shaped segments emerge from cactus aureoles, protected by a circle of defensive glochids and a single large papery spine. As the new segments break through the old ones, they seem to reach out for the warm sun, eagerly awaiting their transformation into the typical mature pine-cone shape. Standing at an impressive height of up to 12 inches, these loosely attached segments can easily detach and fall.

Cultivating the Paper Spine Cactus

Whether you reside indoors or outdoors, you can cultivate your very own Paper Spine Cactus. Just remember, this cactus thrives in 10-to-12 hours of direct sunlight. However, keep in mind that “LESS LIGHT = LESS WATER” is the golden rule to follow when caring for this unique plant. Whether you choose to keep it in a container or plant it in the ground, the Paper Spine Cactus promises to bloom and flourish.

Propagation Made Easy

The stems or joints of the Paper Spine Cactus have a predisposition to break off easily. However, this is not a cause for concern, as these fallen stems can quickly take root and give birth to entirely new plants. Alternatively, you can cut a paddle off the cactus at the joint using a clean knife. Make sure to select a healthy paddle on an actively growing stem. These new paddles, typically grown in spring, have a quick rooting process.

Lay the freshly cut paddle on a paper towel in a location away from direct sunlight. Allow it to cure and dry out for one to two days before planting. Choose a pot with at least one drainage hole and fill it with a cactus soil mix or create your own by combining equal parts peat moss and coarse sand. The potting mixture should be slightly moist but not wet or soggy. Insert the cut end of the paddle into the prepared soil, ensuring that it stands upright on its own. Place the pot in a warm room where it can receive bright, indirect sunlight. Water sparingly to prevent the soil from drying out completely. Within three to six weeks, you will notice new growth, indicating successful rooting. Once rooted, relocate the cactus to a full-sun location, and watch it thrive.

The Art of Self-Defense

While the long white spines of the Paper Spine Cactus may appear formidable, they are actually harmless. Resembling a dagger with a barbed point, these paper-thin spines pose no threat. However, be cautious about the glochids, the tiny spines commonly found on opuntia cacti. These glochids serve as the secret weapon of the Paper Spine Cactus, deterring predators from ever attempting another bite. Once lodged in a predator’s mouth, throat, and esophagus, the glochids ensure they will never crave a Paper Spine Cactus again.

A Short-Lived Beauty

The Paper Spine Cactus is not just admired for its unique appearance but also for its remarkably beautiful white flowers. Each flower lasts only 24 hours, making it a fleeting treasure. Emerging from the areoles, the new flower segments initially resemble the new cactus segments or arm growth. However, as they develop, their distinct characteristics become more apparent.

The milky, pure white petals with hints of yellow and reddish-brown edges create a stunning visual display. The petals encase the bright yellow stigma, while the anthers and filaments form the stamen, the male part of the flower responsible for producing pollen. During pollination, moths, bats, bees, or other insects inadvertently collect pollen on their bodies, transferring it to the stigma. From there, the male reproductive cells journey down the stigma’s tube to fertilize the seeds inside the flower’s ovary. These fertilized seeds are then encompassed by the developing fruit.
