also in shady rocky fissures on densely wooded hills. Altitude 700 -
Conservation status: Listed in
CITES appendix 2.

Cultivation: Very easy to grow.
Watering Needs Need regular water but
do not water again until dry. Also, it is a species that is dormant in
the winter and require very little water (maybe even none) during the
Frost Tolerance: Light frost protection required. Minimum of
5ºC for safe growing (but hardy up to -5°C or less.)
In spite of its preference for shade in the wild, in culture, good
exposure to sunshine will favour good spine development. Can be sunburned if moved
from shade/greenhouse into full sun too quickly. During the spring it may be able to
take full sun until the heat arrives at the end of spring. In an area
that has hot afternoon sun, it may be able to take full morning sun, but
requires afternoon shade or afternoon light shade.
correctly, it will reward the grower with generous displays of yellow
flowers. Clumps will be formed quite readily over a few years.
Propagation: Seeds or offsets that appear at the
base; leave them
attached to form a cluster, or wait until they are 1/3 the size of the
parent and then detach and plant.
A rare white flowering mutant.
