Origin of Name: The name Astrophytum myriostigma Nudum KOHYO reflects the unique traits and classification of this remarkable cultivar. The genus Astrophytum, meaning "star plant," signifies the star-like shapes common to many of its species. The species name myriostigma translates to "many spots," highlighting the distinctive dot patterns on its surface. The term Nudum indicates that this variety is spineless, resulting in a smooth, appealing appearance. The cultivar name KOHYO is derived from the Japanese word for "fertile" or "lush," but here the specific trait is that it changes colo with winter and changing light conditions - sometimes the entire body becomes colored..

Origin of the Plant: Astrophytum myriostigma is native to the arid regions of northeastern Mexico, particularly in areas such as San Luis Potosí and Nuevo León. This species thrives in rocky, well-draining soils and has adapted to survive in harsh, dry environments with plenty of sunlight. The Nudum KOHYO cultivar is especially prized for its unique appearance and is sought after by collectors for its exceptional color hanging characteristics.

Technical Description: Astrophytum myriostigma Nudum KOHYO typically grows to heights of 6 to 10 inches. It features a rounded, globular shape with four prominent ribs and a smooth, spineless surface. The absence of spines makes it particularly easy to handle, while the plant's body often showcases flecks of white or yellow spots that add to its visual appeal. In late spring to early summer, this cultivar produces large, vibrant, yellow flowers that bloom from the apex, creating a stunning contrast against its green body and attracting pollinators.

Conservation Status: While Astrophytum myriostigma is not classified as endangered, it is important to note that habitat destruction and over-collection can threaten its populations. The Nudum KOHYO cultivar, being a distinct and rare variant, is of particular interest to collectors, which emphasizes the need for sustainable cultivation practices. Sourcing this plant from reputable growers is vital for ensuring its conservation and the continuation of its unique characteristics.

Care Instructions: To properly care for Astrophytum myriostigma Nudum KOHYO, consider the following guidelines:

• Light: Provide bright, indirect light or several hours of direct sunlight each day to support healthy growth and vibrant coloration.
• Water: Water sparingly, allowing the soil to dry out completely between waterings. During the growing season (spring and summer), provide moderate watering but reduce it significantly in the dormant period (fall and winter).
• Soil: Use a well-draining cactus mix, such as a blend of potting soil, perlite, and coarse sand, to prevent root rot and maintain optimal moisture levels.
• Temperature: This cultivar thrives in warm temperatures, ideally between 70°F to 90°F (21°C to 32°C) in the growing season, while being protected from frost and extremes of cold.
• Fertilization: Apply a diluted cactus fertilizer during the growing season to encourage healthy growth and blooming, but cut back on fertilization during the dormant months.
