The cv 'Superkabuto', however, is a result of selective cultivation, likely developed in Japan, where there is a strong tradition of cultivating and hybridizing cacti for unique characteristics.

Conservation Status

Care Instructions

Astrophytum asterias cv 'Superkabuto' prefers bright, indirect light but can tolerate some direct sunlight. Too much direct sun, however, can scorch the plant. A well-draining soil mix specifically for cacti is essential. Water moderately in the growing season, allowing the soil to dry completely between waterings, and reduce watering in the winter. This cactus is not frost-tolerant and should be protected from freezing temperatures. Fertilization is not essential but can be done sparingly with a diluted cactus fertilizer during the growing season.
