Mammillaria Bocasana Fred Cristata
The Mammillaria Bocasana Fred Cristata is a fascinating mutation of the well-known Mammillaria Bocasana, famous for its woolly appearance and charming small flowers. In this crested form, the classic clustered growth gives way to sinuous ridges, often flat, twisted, or deformed, making each specimen unique. The "Fred" cultivar additionally stands out with its greenish to pale yellow tones, tiny and sometimes completely distorted areoles, and an almost total absence of visible spines. An exceptional plant for collectors!
This variety does not exist in the wild: it results from mutations observed and then stabilized through nursery cultivation. The classic Mammillaria Bocasana originates from north-central Mexico, particularly the semi-arid regions of San Luis Potosí and Zacatecas. The crested cultivar is propagated only by cuttings due to its unstable form.
To thrive, Mammillaria Bocasana Fred Cristata needs plenty of light but must be protected from overly direct sun.
🌤️ Indoors: Place it behind a well-exposed window (south or west).
☀️ Outdoors: Gentle morning sun or light shade in midsummer to avoid burns on its delicate tissues.
💡 Tip: Insufficient light will cause excessive deformation or unattractive elongation.
