Description: This plant is
an extreme form of this very variable rich in forms species, but it is
not justified the attribution of the rank of variety.
The plants that are today in cultivation with the name “Major”
are plants with high
homozygosis levels derived from the first selected specimens
originally used to describe the new form. This plants was at first
multiplied asexually or by
controlled pollination, so they remained - generations by generation
- almost unchanged in appearance. So the initial extreme types with the
long strongly open cluster of spines involuntary began in the course of
time to be cultivated and is now in our collections as good form. A
whole series of such "European” form and variety of cacti is now
recognized, however in nature plants shows - in the same place too - all
their intermediate forms and passages and grow one to each other.
Cultivation: Keep this plant almost dry in winter at a minimum
temperature of 0°C, prefer a
growth will stop altogether. The plant tolerate
extremely bright situations but enjoy some shade during
the hottest part of the day in summer.
