Tephrocactus articulatus var. papyracanthus, commonly known as Paper Spine Cactus, is a unique and visually captivating cactus variety. It is a subspecies or variety of Tephrocactus articulatus, a cactus species native to South America, particularly Argentina.

The Paper Spine Cactus is characterized by its distinctive cylindrical or columnar stems that consist of segmented joints. These joints are formed by accordion-like folds in the stem, giving it a unique appearance. The stems are typically bluish-green in color and have a papery or parchment-like texture, which gives rise to its common name.

What makes this cactus particularly intriguing are its spines. Instead of the typical sharp, rigid spines found in many cacti, the Paper Spine Cactus has flattened, paper-like spines that are translucent or white in color. These spines can be delicate and may appear almost transparent, adding to the cactus's overall delicate and ethereal appearance.

The Paper Spine Cactus is a relatively small cactus, with stems growing up to around 4-6 inches (10-15 cm) in height. It is a slow-growing plant that forms attractive clumps over time, creating an appealing display.

In terms of care, the Paper Spine Cactus prefers bright, indirect light and can tolerate partial shade. It requires well-draining soil and infrequent watering, allowing the soil to dry out between waterings. This cactus is also relatively cold hardy and can withstand temperatures down to around 20°F (-6°C).

Due to its unique characteristics and compact size, the Paper Spine Cactus is popular among cactus enthusiasts and collectors. It can be grown both indoors, as a houseplant, and outdoors, in rock gardens or succulent arrangements. Its delicate and intriguing spines, combined with its distinctive segmented stems, make it a captivating addition to any cactus collection.
