MAGNETIC BOULE Ø 6 CM AND MAMMILLARIA HAHNIANA
It loves sunlight, so it can be placed in full sun, or in any case in a very bright place.
Therefore, it can also be grown outdoors, in rock gardens.
In nature, it is found in areas characterized by strong temperature variations between day and night, with rains concentrated mainly in the summer season.
For this reason, it resists very well even at very harsh temperatures (even down to -10 ° C), as long as the soil is kept dry.
In summer, water moderately, only when the soil appears dry on the surface, in order to avoid stagnation of water.
In winter, watering should be completely suspended.
From the very first years of life, it produces numerous flowers at the end of spring.
Its flowers, pink or reddish-purple, form a sort of crown on the upper part of the plant.
It is also known as the "old lady".
In nature, it lives in a very limited area - only about one hectare - and is at high risk of extinction due to deforestation.
