Thimble Cactus (Mammillaria gracilis fragilis)
A compact, clustering cactus with star-like white spines that sparkle in bright light and form dense, playful mounds over time.
Ships in 4" pot Sun: Bright window or full sun outdoors Water only when soil is dry Zones: 9–11
- Beginner-friendly and low maintenance, a great starter cactus
- Naturally clumps and multiplies into dense clusters
- Bonus: may bloom with tiny cream-white flowers in spring under strong light
- Non-toxic, but keep out of reach of pets and children due to spines
What you’ll receive: A healthy, rooted Thimble Cactus in a 4" pot. Starter cluster is typically about 2–3" across, hand-picked and packed in Fallbrook, CA.
After arrival
Unpack carefully and place in bright light. If indoors, set near the brightest window (south or west-facing). Handle gently, small offsets can detach; if they do, set them on dry cactus soil and they’ll root.

Transplant tip
If you repot, choose a well-draining 4–5" container with a gritty cactus mix. Avoid oversized pots. Keep the first watering light after planting.
