Happy Thursday, chubby-plant lovers! Today I wanted to briefly discuss this beauty of a plant, Astrophytum Myriostigma!
Astrophytum Myriostigma, commonly known as Bishop's Cap or Bishop's Hat, is a stunning and unique species of cactus native to the highlands of Mexico! The Bishop's Hat Cactus is a spineless cacti, featuring 3-8 pronounced vertical ribs which define the cactus' shape when young. The genus name "Astrophytum" literally means "star plant", describing the star-like shape of these ribs which usually come in sets of 5! Bishop's Hat Cacti are a spineless cacti species, growing solitarily with very few basal branches. This fairly large species can slowly grow up to about 3.5 feet (1 m) tall and up to 8 inches (20 cm) wide at full maturity! These unique plants are bright green but are nearly entirely covered with hundreds of tiny, white, hairy scales that give it a silvery-grey color. In lieu of spines, Bishop’s Hat Cacti protect themselves with these fine, chalky scales which form unique patterns on the foliage and should be handled with care since they can easily be rubbed off and will probably not grow back! Astrophytum blooms are a truly stunning event as mature plants are crowned by large, hairy, golden, daisy-like flowers each year! Plants may take six years or more to mature enough to flower, and rarely flower before developing 5-6 ribs and it's namesake, star-like shape. Bishop’s Hat is one of the easier Astrophytum species to grow and is one of the most popular species of Astrophytum! Like other star-shaped cacti, this species does not need much supplemental water and thrives in small containers thanks to their shallow root systems. Provide fast draining soil and err on the side of too dry rather than too wet and you'll find that Astrophytum are downright hard to kill! Kept dry overwinter, Bishop's Hat Cacti can be grown outdoors year round in USDA plant hardiness zones 9a-11b, surviving down to around 20 degrees Fahrenheit (−7 C)
