These corms are on order from Ednie Bulbs through Ball Seed. Clone ranunculus are grown in the laboratory through tissue culture, which makes them more expensive, but it also ensures that they are disease free and the highest quality stock. These are corm size 5-6 which is the LARGEST CORM SIZE AVAILABLE!!! The colors show up differently from different growers, presumably due to difference in nutrients and temperature, so be sure to look at both pictures so that you can get the best idea of what to expect in the appearance of these ranunculus. NOTE: There is no minimum order, but if you buy multiple varieties in quantities of less than 10 your corms may not be labeled. So if you want them to be labeled please purchase at least 10 of whatever varieties you are wanting.
