The hybridizer registered it as 12 inches, he or she did not use poor soil to determine that. If anything it would be the opposite, often a hybridizer achieves premium results, whilst a home gardener w less than ideal condition would not reach that. So a scape may reach 30 inches in the hybrizers green house w jazzed up soil and plenty of water.... but at home in average soil and fluctuating temps being watered once a week.... the scape will not likely reach registered height. I have quite a few that do not reach their reg height, but they bloom fine for me. Also some of the photos do not show the midrib. In my experience, a green throat vs an orange throat is a dependable trait, it doesn't change, and even the lighting or age of the blossom does not change the throat color that much. It may appear faded or maybe even be faded to where there is hardly any throat color left by the end of the day, but the color doesn't change from one to another completely. It is true that first year blooms can sometimes look very different, but usually that is for dl that are heavily ruffled, or patterned ect.
