Obregonia denegrii is such a fascinating little cactus — it looks like something out of a botanical jewel box.
- Native to Tamaulipas, Mexico, where it grows in limestone-rich soils.
- It’s considered endangered due to habitat loss and illegal collection.
- Produces delicate white to pale pink blooms from the center of the rosette. Flowers are surprisingly large compared to the plant’s compact body.
- Light: Bright light with some protection from harsh afternoon sun.
- Water: Infrequent but deep watering during the growing season; keep dry in winter.
- Soil: Very fast-draining, mineral-heavy cactus mix.
