Mantis, I kept thinking about your question as to the size of Blue Ribbon and decided to measure it, because it seem to me that they were much larger. got this pant from Mr. Payne who hybridized it and the blooms measured 5 1/2 inches. I, of course, cannot say what size they would be in your garden, but it is a wonderful plant here, as it re-blooms and it pushes out bloom after bloom. There are at least a few and usually a nice lump once the season is underway.
