 Other details: 
·       This plant is suitable for growing indoors like normal harworthia.   
·        Koelmaniorum grows slowly and can be rotten easily, too.  The plant is not cheap so its soil should be light and take care of it carefully.  You may mix the cactus soil and pumice in small size with the ratio 1:2.  I've been told that it worked.
·       Although Haworthia koelmaniorum naturally occurs in the summer rainfall area, the plants seem to have no problem when cultivated under similar conditions as their winter-growing relatives.
