DESCRIPTION OF THE NEW VARIETY
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—2001). The description is based on the observation of plants grafted on Rosa multiflora understock while growing outdoors in central France, at Malicorne, France.

ORIGIN OF THE VARIETY
The ‘Delgraros’ was created by artificial pollination carried out during 1998 in a greenhouse at Hyères, France, wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Delge’ / ‘Centenaire de Lourdes’ variety by André Delbard-Chabert, before 1958. The male parent (i.e., the pollen parent) was the ‘Adharman’ / ‘Le Grand Huit’ variety by Michel Adam, 1993.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a this new variety.

BACKGROUND OF THE VARIETY

SUMMARY OF THE VARIETY A new and distinct plant ‘Delgraros’ that exhibits the following combination of characteristics:

(a) from a physical point of view forms green mature wood, displays a bushy growth habit with glossy foliage, and forms attractive long-lasting very full pink-colored flowers that bear strong fragrance, and

(b) from a biological point of view forms vigorous vegetation, produces flowers in abundance on a substantially continuous basis, and exhibits good resistance to blackspot and powdery mildew;

The new variety well meets the needs of the horticultural industry and is particularly well suited for growing outdoors as attractive ornamentation.

COMPARISON WITH PARENTS
The new variety ‘Delgraros’ can be readily distinguished from its ancestors in view of the combination of characteristics described herein. For instance, the new variety can be readily distinguished from its ‘Delge’ / ‘Centenaire de Lourdes’ variety parent through an examination of blossoms and overall plant vigor. More specifically, the blossoms of the ‘Delgraros’ variety are larger and possess a greater number of petals than the ‘Delge’ / ‘Centenaire de Lourdes’ variety. Also, the ‘Delgraros’ variety displays more vigorous vegetation than the ‘Delge’ / ‘Centenaire de Lourdes’ variety.

Unlike the ‘Delgraros’ variety, the ‘Adharman’ variety forms dark red blossoms.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The ‘Delgraros’ variety of the present invention also can be readily distinguished from the ‘Delgramau’ / ‘La Rose du Petit Prince’ variety, which was the product of the same cross pollination. The blossoms of the ‘Delgramau’ / ‘La Rose du Petit Prince’ variety possess a lesser number of petals and are lilac in coloration rather than the pink coloration displayed by the present variety.
