ROSE PLANT March 12, 1974 Filed Oct. 25, 1972 United States Patent 3,519 ROSE PLANT Georges Delbard, Paris, France, assignor to Armstrong Nurseries, Inc., Ontario, Calif. Filed Oct. 25, 1972, Ser. No. 300,647 Int. Cl. Atllh 5/00 US. Cl. Plt.--22 1 Claim ABSTRACT OF THE DISCLOSURE An outdoor bush rose of the fioribunda class, with small to medium size semi-glossy leaves, having their lateral margins lifted from the mid-rib. The plant has a This invention relates to a new variety of rose plant of the floribunda class. The plant is a seedling of the out- .door bush type, cultivated primarily for garden decoration. Its hardiness has not yet been completely tested.

The variety was initially propagated by Georges Delbard, at Evry (Essone), France, but the description which follows, and the color plate which illustrates the plant were taken from a plant which was asexually reproduced from the original stock and grown in Ontario, Calif.

The seed parent was Zarnbra, Plant Pat. No. 2,140, and the pollenparent was an unnamed and undissemi nated seedling (Orange Triomphe Floradora). The new variety holds its distinguishing characteristics through succeeding propagations by budding.

Although this new variety sometimes bears its blooms singly, usually it bears from three to as many as twenty or more blooms in large regular clusters, on normal, short to medium length stems. The plant blooms abudantly outdoors, and nearly continuously during the growing season. Its fragrance is slight, tea to spicy.

Ihis new variety of rose plant diifers from its seed parent Zambra in the following particulars:

Whereas the flower of this new cultivar has from 15 to 30 petals plus petaloids, the flowers of Zambra have only to petals plus 'petaloids.

Although the flowers of both the new cultivar and Zambra are orange, with yellow on the reverse side of the petals, the orange color of Zambra is substantially darker than is true of its new offspring.

Whereas the foliage of Zambra is glossy, the foliage of this new cultivar is non-glossy, or semi-glossy.

The bud of the new cultivar is longer than the bud of Zambra.

The pollen parent of this new cultivar is an unnamed, undisseminated seedling of Orange Triomphe Floradora, and is not available for comparison.

The accompanying drawing illustrates the plant in color and shows the flowering thereof from bud to full bloom.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon the Nickerson Color Fan, put out by Munsell Color Co.

BUD

The peduncle is from average length to long, slender to average in caliper, erect, with numerous stipitate glands. The color ranges from near Strong Yellow Green, 2.5 GY7/l0, overlaid with near Strong Red, 5R4/l2, to near Moderate Yellow Green, 2.5GY5/5.

Cit

Before the calyx breaks, the bud is medium in size, for its class, is medium length to long, pointed and ovoid, with foliaceous appendages on the surface of the bud. As the calyx breaks, the color is between Strong Reddish Orange, 10R6/ l2, and Dark Reddish Orange, 7.5R4/ll,

with a lower portion of the exposed petal being near Brilliant Yellow Green, 2.5GY9/8. The inner surface of the sepals carries a fine tomentum. Margins of alternate sepals are lined with a fine tomentum, and margins of others have numerous stipitate glands and some small foliaceous parts which also have stipitate glands on the margins. Apices of the sepals are acuminate. On their outer surface the sepals have stipitate glands.

As the first petal opens, it is average in size, for its class, long, and pointed to urn-shaped. Its color on the outside is near Brilliant Yellow, 5Y9/9, at the base, while theremainder is more vivid thana color between Strong Reddish Orange, --l0R6/l2, and Strong Yellowish Pink, 10R7/ 9. On the inside, there is a basalarea which is near Vivid Yellow, 5Y8/ 12, while the remainderis more vivid than a color near Strong Reddish Orange, l0R6/12.

The bud opens up well, and is not retarded, or prevented from opening, by cold, hot, wet, ordry weather.

BLOOM others becoming open.

At first the petals remain somewhat cupped, with tips reflexed outward, becoming later at maturity more loosely cupped to flat, with tips refiexed outward. Sometimes the inside petals tend to remain cupped, with tips rolled inward in hot weather.

The petals are of medium thickness, moderately leathery, with the inside satiny to velvety and the outside slightly shiny to satiny. The outside petals are broadly obovate to cordate, with apex somewhat flattened. The intermediate petals are broadly obovate to obovate, with apex rounded. The inside petals are obovate to irregular. The colors may be modified by being bordered, shaded and/or washed with other colors.

The paragraphs immediately followingdescribe color values observed in a flower newly openedin .the month of August. The plant had been grown outdoors, in Ontario, Calif.

The outer surface of the outside petal had a basal area which was near Brilliant Yellow, 5Y9/9, the remainder being between Strong Yellowish Pink, 10R7/9, and Strong Yellowish Pink, 7.5R7/9. The inner surface of the outside petal had a basal area which was the same coloration as on the outer surface, the remainder of the petal being between Strong Orange, 2.5YR7/l0, and Strong Yellowish Pink, 7.5R7/9.

The intermediate petal had a basal area,- both on the outer surface and the inner surface, which'waslthe same color as that of .the .outside .petaL'The remainder of-the outer surface was between Strong Orange, 2.5YR7/ 10, and Strong Yellowish Pink, 10R7/9, while the remainder of the inner surface was between Strong Orange, 2.5YR7/l0, and Strong Reddish Orange, 1OR6/ 12.

The outer and inner surfaces of the inside petal had a basal area which was also Brilliant Yellow, 5Y9/9. The remainder of the outer surface of the inside petal was between Strong Orange, 5YR7/11, and Strong Yellowish Pink, 10R7/9. The remainder of the inner surface of the inside petal was between Strong Orange, 2.5YR7/10, and Strong Orange, 2.5YR6/12.

The paragraphs immediately following describe the color values observed in a bloom which had been open for three days, outdoors, in the month of August. The I plant had been grown outdoors, in Ontario, Calif.

The outer surface of the outside petal had a basal area somewhat lighter than Brilliant Yellow, 2.5Y9/9, while the remainder was between Strong Yellowish Pink, 10R7/9, and Strong Yellowish Pink, 5R7/9. The inner surface of the outside petal had a basal area slightly lighter than Brilliant Yellow, 2.5Y9/ 9, the remainder being between Strong Yellowish Pink, 7.5R7/9, and Deep Yellowish Pink, 5R6/11.

The outer surface of the inside petal had a basal area near Brilliant Yellow, 2.5Y9/9', while the remainder ranged from Light Orange, 5YR8/ 7, to Strong Yellowish Pink, 7.5R7/9. The inner surface of the inside petal had a basal area which was near Brilliant Yellow, 5Y9/9, the remainder being between Strong Yellowish Pink, 7.5R7/ 9, and Strong Reddish Orange, lR6/l2.

The general color effect of the newly opened flower was a color near but more vivid than Strong Reddish Orange, 1OR6/ 12. After being three days open, the bloom gave a general color effect of between Strong Yellowish Pink, 7.5R7/ 9, and Strong Reddish Orange, 7.5R6/l2.

The petals usually drop off cleanly, although some petaloids, dead peduncles and receptacles may persist.

The flowers are not particularlyaffected by cold, hot, wet, or dry weather. On the bush in the garden, they may persist for from four to five days in the month of August, in the locality named. Cut roses grown outdoors and kept at living-room temperatures will last from four to five days in the month of August.
