Introducing the marvelous Nellie Cory Cactus, also known as the 'Escobaria minima grafted'! This adorable little cactus is bursting with personality and got its common name, Nellie cory cactus, as a tribute to Nellie Cory, a renowned botanist who extensively studied and contributed to the understanding of cacti. Nellie Cory's significant contributions to the field of botany, particularly in the study of cacti, led to this particular species being named in her honor.  

With its spheric to cylindric stems that can grow up to 6 inches tall and adorned with conical tubercles, this Escobaria cactus is an absolute showstopper. And let's not forget about those thick, corky white spines - dense clusters of pale tan to pinkish gray that give it a touch of elegance and charm. Plus, at the top of the stem, it produces funnel-shaped pale-rose to magenta flowers that bloom in the mid-spring. 

Escobaria minima is a small, low-growing cactus that is native to the southwestern United States and northern Mexico. It prefers bright, direct sunlight for at least 4-6 hours, so you should place it in a location that gets plenty of light. During the growing season, which is typically from spring to fall, you should water your Escobaria cactus once every 2 - 3 weeks. However, during the winter months, you should reduce watering to once a month. It's important to use well-drained specialized cactus potting soil and a pot with drainage holes to prevent the roots from rotting. Additionally, you should fertilize your cactus once a year during the growing season in the spring to help it thrive. 

The slow-growing indoor cactus prefer a noticeable temperature difference between the night and the day during the growing season. It can grow outside in USDA zones 9-11. As opposed to other varieties of this Escobaria, this one has a lower rate of seed germination, so other techniques, like offsets or cuttings, are actually preferable.
