Disagree. I showed it yesterday at the San Diego county fair as a miniflora single and it won its class. It is the same size as several other miniflora singles -- Poppy, Sunglow, Maroon 8, Tom Mayhew. It would be much too small to compete in the floribunda single classes like Playboy and Playgirl. The plant itself is also quite small for me -- good for a pot which is how I have it.
Paul Ecke Jr. is not a florabunda -- it is officially classed as a "shrub." Moreover, here it has smaller miniflora-like size flowers, but generally in large, fairly widely spaced clusters, on a big plant. Shannon's Delight generally forms its blooms singly, and on a small plant. The possible variations on plant size and bloom type in roses are endless, and any classification system is bound to have outliers. C'est la vie.
