Astrophytum myriostigma aka Bishop's Cap

Taxonomy

Astrophytum myriostigma, also known as the bishop's cap cactus, bishop's hat, or bishop's miter cactus, is a species of cactus native to the highlands of northeastern and central Mexico. It is a small, thornless succulent cactus that forms a spherical or shortly columnar shape, reaching a height of up to 20cm. The plant has light yellow flowers that are approximately 5cm across, sometimes with a reddish center, and they bloom in the summer. This cactus is characterized by its ribbed grey-green stems, which are spineless and asymmetrical, giving it a star-like shape. It is also known for its unique appearance, which led to its popularity when it was introduced to European countries in the 19th century. The stems can grow up to 7.9 inches (20 cm) tall, and the cactus is covered with small white spots. Its flowers typically appear in spring or early summer and can take several years to bloom as the cactus develops slowly.
