Hi Diane, I belong to the clivia enthusiast group and have read through a good portion of their archives, so I far as I understand clivia will not grow from root cuttings. Haven't tried it myself, there are two other very knowledgeable clivia people in this group that may tell you otherwise. I'm absolutely tickled that of my clivia seed choices this year I was able to get a good number of variegated plants. Linda Foulis Okotoks, AB Canada above zero, and the snow is almost gone!
