Tephrocactus articulatusPaper spine cactus, Pine cone cactus
Native to western Argentina
Cultivation: It is easy to grow but usually couldn’t get very tall as segment kept falling apart. It is fairly cold resistant and hardy to -9°C depending on the clone, Need full sun, (with insufficient illumination stems and spines get thinner as a result of the lack of sun) The main growing period is spring. It might produce some new segments in the autumn too. Needs good drainage. Propagation is through segment cuttings, or occasionally seeds The little glochids at the base of these larger spines are quite a nuisance, and it is best to use gloves to handle this plant.
Propagation: Cuttings, it suckers profusely and is very easy to grow by just knocking off one of the ‘cones’ and stuffing it in the ground.
