Cosey (I guess the name is Karma Choc, I just always assumed it was an abbreviation for the real name). When the Karma series came on the scene cut dahlias were just starting to gain popularity. The Karmas came with instructions for commercial growers who had never grown dahlias for cut. The whole package was well done. A grower could buy rooted cuttings (plugs) for $.85/ea, top them at 8-10 up, cut them once at ground level, and make a good profit. The first large-scale growers here didn't dig/divide/store tubers, they would just buy new cuttings every year. Dahlias were raised similar to how tulips are raised commercially. With the huge increase in popularity recently it has been difficult to find plugs of dahlias so some of the growers have started saving tubers.
