Coryphantha werdermannii PP200 Hundido, Coah. Mx.
After a youth-stage of 7 to 12 years, with purely
smooth radial spination suddenly strong central spines appear on the
top, which finally cover the whole body and which are responsible for
the wild look.

Spines shape and colour
are quite variable. |

This species is one of those Coryphanthas
which pass a purely radial-spined long youth stage in which they are
already floriferous. Most of the plants after several years
develop the central spines, giving the plant its sea urchin
appearance.

Coryphantha werdermannii PP200
A ten years old seedling but with still juvenile spination.
This species is very slow growing and not very willing to flower, in
fact they will flower only when they reach the age of 8 to 14 years.
Cultivation: Somewhat sensitive to overwatering (rot prone) and very slow-growing.
Because of it’s small size makes a great potted
plant specimen, usually reserved to experienced collectors,
Grow in a mineral
cactus compost, requires good
drainage.
Water in moderation, keep drier in
winter.
Full sun to
partial shade but is tolerant and prefers light shade during
the hot Summer months.. Provide very good
ventilation. Frost Tolerance: Hardy to - 5°C if kept dry.Propagation:
Seeds as usually shoots are not available.
