Gymnocalycium mihanovichii var. friedrichii f. Rubra hort.

ENGLISH: Ruby Ball, Red Cap Cactus, Red Hibotan, Hibotan

Description: Gymnocalycium mihanovichii friedrichii 'rubra', or 'Hibotan' comprises a large group of popular mutants, characterized by more or less red coloured bodies. They are red (but also orange, dark purplish, yellow or even white) because they contains few chlorophyll or even no chlorophyll at all, much like the red we see in the fall foliage of trees when their chlorophyll breaks down and disappears. Without chlorophyll many of these mutants gymnocalyciums can not produce sugar and without sugar they will die. The only way to keep them alive is to graft them onto another cactus which has chlorophyll and which will provide sugar to the mutant scion. The chlorophyll containing bottom part of the graft, called the stock, can be any number of different cactus species. In the case of the gymnoclyciums it is usually Hylocereus, a tropical cactus. The oldest and more famous mutant is the bright orange-red and completely chlorophyll-less cultivar "Hibotan" often known as the “Red Cap Cactus”, or “Ruby Ball”. While the yellow and paler forms are sometime known as “Blondie” or “Moon Cactus”.
