The early Cockers were not notable rose breeders. Their first varieties, brought out in 1892, were two chance sports from Hybrid Perpetuals. One was a deeper coloured flower found among their stock of the carmine 'Etienne Levet', and introduced as 'Duke of Fife'; a pale variation among the pink 'Countess of Roseberry' became 'Duchess of Fife"...

Hybrides Remontants. Groupe I. — Madame Victor Verdier
Ce groupe se rapproche beaucoup de celui des "Charles Lefebvre"; on dit communément des rosiers qui le composent que ce sont des "Général Jacqueminot" à bois lisse: ils sont très florifères, franchement remontants. Rameaux lisses, verts, aiguillons petits et rares; feuillage vert, moyen; fleur en coupe, floraison le plus souvent en corymbe; on y rencontre les coloris les plus variés, du rose au rouge pourpre noirâtre.
4394. Duchess of Fife... (Cocker 1893)... cramoisi.
