Astrophytum myriostigma #cactus #shorts

Astrophytum myriostigma, Bishop’s Cap Cactus, Bishop’s Cap or Bishop’s Cap Cactus, is a cactus native to the northeastern and central highlands of Mexico. A. myriostigma is a thornless cactus defined by the presence of three to seven (usually five) distinct vertical ribs that define the shape of the cactus in its youth (genus name “astrophytum”, literally ” star-shaped plant”, from the resulting star). As the cactus ages, possibly adding more ribs, it becomes more cylindrical in shape, growing to about 70-100 cm (2 ft 4 in to 3 ft 3 in) tall and 10-20 cm ( 4-8 inches) diameter. In the wild, bulbous to cylindrical stems are covered with white trichomes. Some horticultural varieties lack flocking. In the wild, cacti bloom in early spring so their seeds can grow in the summer rain. In cultivation, things are different and plants may bloom in summer. Plants produce one or more flowers 4-6 cm (1.6-2.4 in) in diameter near the apex; numerous tepals are creamy yellow, sometimes with orange or red bases. Pollinated flowers develop into hairy red fruits about 2-2.5 cm (0.8-1.0 in) in diameter. Plants can take up to six years to flower. A. myriostigma is commonly grown as an ornamental in cactus collections. This plant has won a Garden Merit Award from the Royal Horticultural Society. .
