Claims priority, application France, Oct. 12, 1%7,

Int. Cl. X0111 /00 US. Cl. Plt.--18 1 Claim The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the rose variety known in France as Super Star (better known in the United States as TropicanaU.S. Plant Pat. No. 1,969) with the rose variety known as Romantica (unpatented) As the result of this breeding, I have produced a new and improved rose variety which is distinguished from its parents, as well as from all other varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding in the new variety:

(1) A regular and good plant habit;

(2) A healthy leaf system, with the foliage being borne in abundance;

(3) An abundant and continuous flowering habit, particularly during the winter months;

(4) Blooms of elegant form and of average size and usually born singly and erect on sturdy, relatively stiff stems, with the blooms having good petalage;

(5) A distinctive, attractive, delicate and warm, pale pearly pink general color tonality of the flowers;

(6) Good resistance to frost and other bad Weather conditions and to diseases commonly attributed to roses, as compared with other rose varieties grown in France under the same conditions;

(7) Excellent adaptability to various grafting stocks under widely varying climate and soil conditions;

(8) Excellent adaptability to forced cultivation under glass;

(9) Good shipping qualities; and

(10) Excellent lasting qualities of the flowers as cut flowers.

Asexual reproduction of my new variety, particularly by so-called shield-bud grafting, as performed by me at Antibes, France, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawings show a typical flower specimen of my new variety in the opening bud stage of development, as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character, and also the drawings show in black and white typical vegetative and flower specimens in different stages of development.

The following is a detailed description of my new rose variety, with color terminology in accordance with Rene Oberthurs Repertoire de Couleurs, except where general color terms of ordinary dictionary significance are obvious:

Type: Hardy;'bush; seedling; for outdoor and for greenhouse cultivation and particularly for cut flower use. Class: Hybrid tea. Breeding: Seedling.

Seed parent.Super Star (known in the United States as Tropicana"). Pollen parent.Romantica." Locality where grown and observed: In the spring in a hothouse, at Antibes, France.

Leaves.Numerous; cover the plant and the flowerbearing stems With elegance. Form: Usually compound of 7-5, rarely 3, leaflets from base of branch to tip, with 5 leaflets on the rachis at regular intervals arranged in opposing pairs and with 1 terminal leaflet. Size: From average to large lengthfrom mm. to mm., and sometimes from mm. to mm., from the branch point to the point of the terminal leaflet; width-from 80 mm. to 90 mm., and sometimes from 120 mm. to 130 mm., between tips of opposite leaflets below the terminal leaflet.

Leaflets.Shape: Ovoid; symmetrical to central vein;

rather deeply serrated about margins. Size: Terminal leaflet is the largest and basal leaflets are always small, with successive pairs diminishing progressively from about 50 mm. to 30 mm. to about 40 mm. to 25 mm. on the average, with largest ranging between 65 mm. to 45 mm. and 50 mm. to 35 mm., with basal leaflets ranging between 25 mm. to 15 mm. and 30 mm. to 20 mm.

Color (mature).-Upper surface: American Green, Hues 3-4, Plate 237. Reverse surface: Pea Green, Hue 1, Plate 277.

Color (on young sh00ts).Reddish.

Surface.-Upper: Glabrous; smooth; with thin furrowed veins. Under: Opaque; veins protrude somewhat.

Rachis.Sturdy; almost cylindrical; with a visible groove on the obverse side; divided into regular sections between the insertions of the petioles of the leaflets.

Stipules.-Adnate to the base of the rachis over a length varying from 15 mm. to 25 mm., and then divided into 2 auricles.

FLOWER Peduncle: Course; stiif; substantially uniform in section; well detached; upper half generally smooth; lower half studded irregularly with small thorns of unequal size;

average length about 100 mm. from the flower to the first leaf.

Bud:

Shape-Elongated ovoid, with a sharp tip.

External guard petals-Color: Near Saffron Rose,

Hue 2, Plate 124.

Size (on an everage stem and when sepals start to lsen).Length: From 22 mm. to 28 mm. Width: From about 17 mm. to 28 mm.

Sepals.Detached from corolla rather early and gradually assume a horizontal position as the flower opens.

Flower: Average size and duplicature; opening forms at all stages correspond to the classic type of rose flower; petals roll outward as opening progresses and impart to the flower a rounded rosaceous form as long as flower lasts.

Size.-About 100 mm. in diameter.

Habit.--Erect; borne singly; with straight axis along the stem.

Fragrance.Fruity.

Colon-General color tonality over all is Rose Salmon Carmine, Plate 124 with warm and luminous brilliance over the heart of the flower.

Calyx.Conical at the base of the calyx or receptacle, suggesting an inverted funnel with the narrower opening being the upper portion of the peduncle.

Receptacle.Small. Color: Pale Green.

Sepals. in number, with 3 having numerous foliaceous appendages which are more or less glandular and the other 2 having solid edges; intercalated, with their positions as follows: 2 leaflike sepals sideby-side, 1 sepal with solid edges, 1 leaflike sepal, and one sepal with solid edges; of the 3 leaflike sepals, one is often longer and more fringed than the others, with the terminal portion being elongated and with serrated edges more pronounced in the lower portion; sepals with solid edges have elongated triangle shape, curve inward and terminate in a very sharp point. Color: Reverse surface-Near Meadow Green, Hue 5, Plate 268; obverse surface-Downy whitish, except for the terminal portion of the leaflike sepals which are the same color as the bush leaf, i.e. American Green, Hue 4, Plate 237.
