Mammillaria polythele – Rare Columnar Cactus | Exotic Plant World

Mammillaria polythele is an elegant columnar cactus species native to Mexico, admired for its tall, ribbed, and spiny structure. Unlike most Mammillarias that stay globular, polythele grows upright into slender columns, forming clusters over time.

Its dense white to golden spines and purple-pink flowers make it a centerpiece in any cactus collection.
Ideal for collectors and hobbyists, it combines the charm of Mammillarias with a unique vertical growth habit.

🌡️ Temperature:

• Optimal: 18°C–32°C
