Description
Tephrocactus papyracanthus is a distinctive opuntioid cactus composed of segmented, cylindrical to club-shaped joints. The plant is best known for its flat, papery, translucent spines, which overlap and give it a delicate, almost artificial appearance. The segments are grey-green to bluish-green, sometimes with a slightly glaucous coating. Areoles are well spaced and produce numerous flattened spines that can reach several centimeters in length.
Flowers are borne near the tips of the segments and are typically white to pale pink. Flowering occurs in spring to early summer. Native to arid regions of Argentina, this species is adapted to extreme drought and prefers a very mineral, well-drained substrate, sparse watering during the growing season, and a dry winter rest. It is highly valued by collectors for its unusual spination and sculptural form.
