Grafted Moon Cactus (Gymnocalycium mihanovichii and Hylocereus): The grafted cactus measures approximately 3.0 inches in height, featuring a brightly colored G. mihanovichii positioned atop a green Hylocereus rootstock. The grafted cacti on the top lack chlorophyll, thereby revealing the pigmentation of their coloration. As chlorophyll is essential for photosynthesis, these cacti can only survive due to their grafting onto a Hylocereus cactus that contains normal chlorophyll levels.
