Mammillaria spinosissima cv. 'Un Pico'

This cactus isn’t trying to blend in — ‘Un Pico’, meaning “one spine,” is a rare cultivar of the classic Mammillaria spinosissima that produces just a single spine per areole, giving it a spaced-out, almost stylized look. Its spines are long and dramatic, arranged like tiny exclamation points across a green, cylindrical body.

It’s a sun-lover and thrives with the classic cactus routine: bright light, dry soil, and a little patience. When it blooms, it offers a soft ring of small pink flowers, wrapping its edgy look in a sweet crown.

🪴 Bigfoot’s Tip: Rotate it regularly to keep its growth balanced, and give it room to stretch — it’ll get tall over time!
