I have a suggestion. As we all know, I'm sure, many cultivars are being mislabeled and passed around as the wrong plant. Now, the official list of cultivars is on the ICPS website right? Why don't they make a rule that with the submission of the cultivar, you have to include a picture. That way people will have a better idea of what say D. 'Marston Dragon' is SUPPOSED to look like. If the picture came from the original registerer, it would have to be bonafide right?
Would this be too difficult?
