M. Philip Le Cornu, rosiériste à Jersey, met en vente depuis novembre dernier (1912): DUCHESS OF NORMANDY (Hybride de thé). C'est un Dean Hole à fleurs jaune crème. Comme forme, vigueur et mode de végétation, cette nouveauté est identique à Dean Hole dont elle se différencie par son superbe coloris qui est jaune, non pas d'un jaune uniforme, car toutes les teintes de cette couleur se rencontrent sur ses pétales, avec deux tons prédominants : le jaune d'or et le jaune saumon. Une remarquable particularité la concernant est que chez les fleurs coupées le jaune s'intensifie de jour en jour. En résumé, c'est une rose magnifique que nous verrons bientôt dans toutes les expositions.

Notes on Newer Roses.
Hybrid Teas.
Duchess of Normandy (P. Le Cornu, 1912). — A yellow sport from Dean Hole, exhibited by the raiser at Southampton this year, where it received a card of commendation and might, perhaps, have had a higher award.  I was very pleased with it, and I think due allowance having been made for the Jersey soil, and further, the Jersey climate, with its almost perpetual sun, preventing that slow development of the bud which is so essential to produce the exhibition flower, it is a really promising sport that should do well in our English gardens.  A yellow Dean Hole hardly does justice to its colouring.  It is not, at any rate, a yellow self, but has many shades of colour amongst its petals, salmon and gold predominating.  Altogether a beautiful Rose that I expect to see in most exhibition boxes before we are much older.  It is being distributed at 5s. each.  Duchess of Normandy, by the way, is the Jersey man's title for Queen Mary.
