Tephrocactus articulatus var. syringacanthus 6.5cm
Tephrocactus articulatus var. syringacanthus (Pfeiff.) Backeb.
T. articulatus is an exemplar of cactus very easy to cultivate because it resists very well to the temperature differences.
Its name comes from the Greek and means "ash", in reference to its usual colour tending to greyish, but probably also due to the spontaneous growth of different species on the ashes of the volcanoes.
Its stem has a globose shape, tuberculated and with big white and woolly areoles. From these ones come out some flattened thorns, of white colour and that are very long.
The flowering period is spring, the beautiful flowers bloom at the top of the plant; they are very delicate with shades ranging from white to yellowish.
- It likes an exposure to full sun in rather airy locations.
- It is preferable to keep it at mild temperatures and never below 5 °C, for this reason it is recommended to shelter it during the winter period.
- Water moderately, only when the soil is completely dry. It is enough to water the plant once a week in spring and summer, once a month in autumn and to suspend watering completely in winter.
- The best option is a well-draining and porous soil, even better if further enriched with 50% of inert materials such as pumice or lapilli.
- They do not need frequent fertilization, it is sufficient to dilute the fertilizer with watering once a year.
