Astrophytum Myriostigma | Bishop’s Cap Cactus
This is a popular variation of the Bishops Cap cactus from the highlands of Central and Northern Mexico. Elevations ranging from 750 to 1500 metres above sea level. This cactus grows with five ribs. There is also a four ribbed variety.
Astrophytum myriostigma (many dots) is a spineless cactus. Quadrangular to almost spherical, the plants become shortly columnar with age. It is covered with many minute white hairy scales that give it a characteristic chalk-white or silvery-grey appearance. A transverse section of the stem reveals a perfect star shaped form giving the plant the appearance of a bishop’s mitre (hence the common name Bishop’s cap). The stems are smooth and can be over 90 cm tall and 5-10 (-20) cm in diameter.
A. myriostigma flowers independently of day length, flowering intermittently throughout the warm months from the end of winter to the start of autumn.
Age: 4 – 6 years. These A. myriostigma cacti are flowering.
