It only grows to be 4 cm high and has a 5-6cm diameter Flowers of this species have a silky appearance and range from white, greenish/tan to pink. G. mihanovichii has given rise to several hybrids and colour mutants (lacking chlorophyll), the more famous of them are the cultivars ‘Hibotan' ( a pure red mutant) and ‘Hibotan nishiki' (the variegated form) The colour mutants partly or totally lack vital functions and therefore can only survive as grafted specimens, obtaining their nourishment from a green stock plant to with which they are united
