Mammillaria Spinosissima
The Mammillaria Spinosissima is one of the most popular and decorative cacti of the Mammillaria genus, thanks to its colorful spiny crowns and spectacular flowering. Sometimes nicknamed the “hedgehog cactus”, it has a cylindrical shape, sometimes branching at the base over time. This cactus is densely covered with white, red or golden spines depending on the variety, creating a striking visual effect.
Its most appealing feature remains its crown-shaped flowering: small bright pink, sometimes mauve, flowers forming a regular halo around the top of the cactus. This flowering can last several weeks in spring or summer, especially if the plant has been properly overwintered.
The Mammillaria Spinosissima is native to Mexico, particularly the mountainous regions of Guerrero and Morelos. It naturally grows on rocky slopes in semi-arid areas, exposed to intense sunlight while benefiting from cool nights.
These natural conditions explain its high tolerance to drought, as well as its preference for a well-ventilated environment and a mineral substrate.
