It has soft
stems obscured by spines, If grown correctly, it will recompense
the grower with generous displays of amazing flowers. When not in
flower, the body is not much different from the familiar
Mammillaria bocasana
Cultivation: One of the more difficult species to grow
long enough to produce clumps.
Watering
Needs Need regular water but do not water again until dry.
as it is specially sensitive to over
watering; plants should be allowed to become crowded in their pot.
Keep in shallow pot.Also,
it is a species that is dormant in the winter and require very little
water (maybe even none) during the cold months.
Frost Tolerance: Light frost protection
required. Minimum of 5ºC for safe growing (but hardy up to -5°C or
less.)
Sun Exposure: High levels of light are needed to
flower and for 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.
If grown correctly, it will reward the grower with generous
displays of purple flowers.
Propagation: Seeds (usually) 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.
