Mammillaria Compressa
The Mammillaria Compressa is a cactus highly appreciated by collectors for its dense growth habit and its ability to form large colonies of offsets over the years. Native to Mexico, it is emblematic of the diversity of species within the Mammillaria genus, renowned for its abundant flowering and robustness in cultivation.
Its globular to cylindrical shape is covered with conical tubercles arranged in a spiral. Each areole bears fine radial spines and stronger central spines that are sometimes slightly hooked. Over time, the Mammillaria Compressa can form an impressive cushion of clustered heads, reaching more than 30 cm in diameter.
During the flowering period, it produces pale pink to bright pink flowers that form a delicate crown around the apex, creating a striking contrast with the deep green epidermis and the whiteness of the spines.
🌞 Direct sunlight: at least 5 hours per day.
🌤️ Summer protection: light shade during the hottest hours will prevent yellowing of the epidermis.
A lack of light slows growth and prevents flowering.
🌱 Spring / summer: water every 2 to 3 weeks, when the substrate is completely dry.
🍂 Autumn / winter: no watering if the plant is overwintered in cool conditions.
⚠️ Tip: excess water is the main cause of mortality; use a perfectly draining substrate.
🌞 Ideal: between 20 and 28°C.
❄️ Minimum: down to 2–3°C when kept dry, but it is best to avoid any frost.
🏠 Overwintering: in a cool, bright place (garage, unheated conservatory).
🪨 Optimal composition: 1/3 cactus potting soil, 1/3 pumice, 1/3 pozzolana.
🌸 Season: from March to June.
🌈 Color: pale pink to deep pink.
🕑 Duration: each flower remains open for several days.
💡 Tip: a dry winter rest period encourages flowering.
