Are you sure it is the same rose? The powers that be at the big producers lately have been just changing their word order lately to name a new rose cultivar. For example Peach Sunblaze is a different rose than Sunblaze Peach. Argh!!!
Page 86 of Beales' catalogue gives the Varietal code as NOAla, so yes, I am sure. Different countries seem to like playing around with names. I must admit, to my ear, Coral Flower Carpet has a smoother sound to it than Flower Carpet Coral. Did you notice the same switch with Cherry Flower Carpet?
This cultivar is listed as triploid in the paper 'Pollen diameter and guard cell length as predictors of ploidy in diverse rose cultivars, species, and breeding lines'
"Origin and Breeding Controlled pollination: seed parent ‘Repandia’ (F1 seedling) x pollen parent ‘Red Summer’. The seed parent is characterised by its taller height (1500mm) and spreading habit, with single soft pink flowers that only appear once per year. The pollen parent is characterised by its shorter height (700mm) and spreading habit, with semi-double orange/red flowers. Hybridisation took place in Gutersloh, Germany. "
