 Origin: Tephrocactus floccosus (T. rahuii) is found widespread
from
central-Northern Peru to Bolivia in
the Andean High Plateau
Habitat: This plant
grows in dry valleys, rocky slopes and among bushes
in high elevation tropical alpine
habitats. This region has a marked dry season and overnight temperatures
that drop often below 0°C ( to -15° C ).
The typical form of T. floccosus
in central Peru has a dense covering of long hairs that
protect from freezing temperatures, comparisons in habitat with
'hairless' forms showed that the hairy type maintain an epidermal
temperature several degrees higher during the night.

T. floccosus grows almost on the ground and forms large woolly-haired
compact cushions.

T. rauhii (floccosus) KK 393, Huancayo, Junin, Peru,
Altitude: 4000m
(in cultivation)
Cultivation:
Not easy, because of the mountain environment in which the plants live,
they need as much direct sun light as possible to encourage the heaviest
spines an wool formation, plants in shaded positions grows etiolated and
fail to produce the typical hairy covering.
They need to be kept in a cool place during
the winter rest (at 0
to -10°C) this is important for the flowers as well as for their health. They are quite winter hardy and
can be cultivated outdoor, if adequately protected from the rain and
kept perfectly dry.
Needs good drainage, water sparingly (rot prone). |

Propagation: Cuttings, seeds.
