Description :

Chirita "Moonlight" (Boggan) Medium blue-purple. Green and silver markings, compact.

Chirita "Blue Moon"(Boggan) A stemless rosette that grows about 12” across. Blue-purple flowers over dark bluish-green leaves

In my place, two kinds of flowers look almost same and pattern on the leafs are hardly being distinguished. The silver markings only presented under the low temperature or high temperature difference enivorment, In hot summer at north of Taiwan, 34 Cin Day and 29 C in night, the markings will disappear and turns leafs into almost green.
