Tephrocactus articulatus var. papyracanthus: The Paper Spine Cactus
Tephrocactus articulatus var. papyracanthus is a unique cactus species known for its distinctive, papery spines. It’s also commonly referred to as the Paper Spine Cactus.
Key Characteristics:
* Spine Appearance: The most striking feature is its flat, papery spines that resemble raffia fibers. These spines can vary in color and length, adding to the plant’s aesthetic appeal.
* Growth Habit: It’s a shrublet that grows in an upright manner, often reaching heights of around 12 inches.
* Segments: The plant is composed of cylindrical segments that resemble pine cones. These segments are typically silver, glaucous, or green in color.
* Flowers: Though rare in cultivation, the Paper Spine Cactus can produce white, bell-shaped flowers with yellow centers during late spring or early summer.
Cultivation:
* Sunlight: This cactus thrives in full sun conditions.
* Watering: It requires moderate watering during the growing season but should be kept dry in winter.
* Soil: A well-draining cactus or succulent soil mix is ideal.
* Propagation: Propagation is typically done through cuttings or seeds.
Note: While this cactus is relatively easy to care for, it’s essential to handle it with caution due to the presence of glochids (tiny, barbed spines) that can irritate the skin.
