Why You’ll Love It

Compact and Clustering Form
Rounded green stems reach 5–8 cm in diameter and gradually form offsets, developing into a neat, attractive clump over time.

Distinctive Spine Pattern
Radiating hooked spines and longer central spines create its signature pincushion look—both textured and visually appealing.

Seasonal Floral Display
In spring and summer, expect charming funnel-shaped blooms in pink or lavender, often forming a complete crown near the top of the stem.

Perfect for Small Spaces
Its slow growth and modest size make it an excellent candidate for sunny windowsills, containers, or curated cactus gardens.

Tolerant of Light Frost
When kept dry, it can withstand brief drops to –2 °C, offering added flexibility for growers in cooler regions.

Care Guide

• Light: Thrives in bright, direct light. Ideal for sunny windows or protected outdoor locations.
• Water: Water deeply but only when the soil is completely dry. Reduce watering drastically in winter.
• Soil: Requires well-draining cactus mix with added pumice or coarse sand for optimal root aeration.
• Temperature: Prefers warm conditions (18–28 °C); protect from damp, cold environments.
• Fertilizer: Feed once a month during active growth (spring and summer) with diluted cactus fertilizer.
• Propagation: Easily propagated by separating offsets. Allow cut surfaces to callous before replanting.
