It is a globular to cylindrical cactus that can grow up to 12 inches tall and 18 inches wide. Its stems are covered in many sharp spines, and produce large flowers (up to 6 inches in diameter) with white or pink petals. The flowers are not only showy but have a light-pleasing scent, they open in the evening and close by midday. Light/Soil/Water: - Light: When grown outdoors, it prefers full sun and should be placed in a bright window when grown indoors. - Soil: Use a sharp well draining soil, and allow all excess water to run off every time you water. - Water: Water it deeply during the growing season (spring and summer) and sparingly during the winter.
