Mammillaria pringlei is a fascinating species of Mammillaria rhodantha that belongs to the Mammillaria genus. Native to Mexico's Baja California Peninsula, the Mammillaria rhodantha pringlei is mistakenly known as lemon ball cactus despite its true name being Parodia leninghausii. 

Mammillaria pringlei cactus has a distinctive cylindrical shape with numerous tubercles or small bumps covering its surface. These tubercles are arranged in vertical rows, giving the cactus a pincushion-like appearance. The Mammillaria cactus can grow quite fast, reaching heights of up to 6 feet and spreading outwards with a diameter of around 3 feet. 

This Mammillaria cactus has long, needle-like spines that can be golden-yellow or reddish-brown in color. These spines not only serve as a defense mechanism against herbivores but also provide shade to the cactus, protecting it from excessive sunlight. 

The flowers of the Mammillaria pringlei bloom from atop during the spring and summer months. The flowers are usually a vibrant shade of pink or magenta and have a tubular shape. These blooms attract pollinators such as bees, butterflies, and hummingbirds, adding a splash of color to the arid landscape. 

As a desert plant, Mammillaria pringlei is well-adapted to survive in harsh conditions. It has a deep taproot system that allows it to access water from deep within the ground. This helps the cactus withstand droughts and periods of limited rainfall. 

In its natural habitat, Mammillaria pringlei can be found growing in rocky areas, slopes, and arid desert regions. When it comes to Mammillaria pringlei care, it prefers well-draining cactus soil and requires plenty of full sunlight to thrive. Mammillaria pringlei is generally suited for outdoor cultivation in zones 9 to 11, where temperatures can remain above freezing year-round. This cactus is not frost-tolerant and can be damaged or killed if exposed to freezing temperatures below 25 F. You can propagate your Mammillaria pringlei by seeds. 

Additionally, the Mammillaria pringlei is safe for both humans and pets. While the spines can cause physical injury if touched, the cactus itself is not known to be toxic if ingested. Give this Mammillaria pringlei a try if you're looking for an easy plant to care for!
