The neat flowers, small and shapely, had their yellow all flushed towards golden apricot, and marked with pink or red flushes, mostly on the outer petals. It came as a sensation in 1956, from Herbert Swim of Armstrong Nurseries; the parents were 'Fandango' x 'Pinocchio' . Although it was to prove a valuable parent, its career in cultivation was strange, for it divided into at least three separate types; one was vigorous and coarse growing, with too many buds in an ugly cluster, and pale flowers; the second was the true ' Circus' ; and the third was much deeper in colour, not quite so strong as the true one, and with fewer petals.   Before these variations were appreciated, those who collect wood for propagation in nurseries had not unnaturally taken much from the  most vigorous and least desirable of the three, as being the easiest supplier; and there followed a painful period of trying to get rid of it.  But no matter how one selected the propagating material, that brute would come back; The attractive colour of the third type caused Harry Wheatcroft to introduce it in 1959 as 'Alison Wheatcroft'.  A similar but more double sport, and I think a better one, was found in Livermore, California by F. B. Begonia and Paul De Vor, and introduced by Armstrong Nurseries in 1963 as 'Circus Parade'. For some reason these two sports are not so liable to revert as was the true ' Circus' .

L'étude du parfum des roses par Neville F. Miller, spécialiste dans ce domaine, est fort intéressante mais très compliquée pour celui dont le vocabulaire chimique est assez pauvre même dans sa langue maternelle, je vais donc faire mon mieux pour me tirer de cette tâche avec le minimum d'erreurs. (American Rose Annual 1963) ...L'auteur a étudié 170 variétés sous différentes conditions atmosphériques et constaté l'existence de plus de 25 parfums élémentaires et de beaucoup de combinaisons de ceux-ci. Les plus fréquents sont : capucine, iris, violette, pomme, orange, citron, girofle, géranium. Un tableau groupe les 34 parfums principaux et composés, les variétés correspondantes étant rangées en conséquence...
