ROSE PLANT Filed Jan. 22, 1970 United States Patent 3,102 ROSE PLANT David L. Armstrong, Upland, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Calif. Filed Jan. 22, 1970, Ser. No. 5,163 Int. Cl. Alllh 5/00 (1.8. CI. Plt.- 1 Claim ABSTRACT OF THE DISCLOSURE A bushy rose of the floribunda class, tall-growing, moderately branched and moderately vigorous in habit. The plant has compound leaves comprising from three to seven leaflets which are of medium size, moderately thin, somewhat leathery in texture, and semi-glossy in appearance. These leaflets are oval in form, both the apex and the base being acute. The margin is simply serrate. The color of the open bloom is a distinctive strong reddish orange, tinged with yellow on the underside of the petals. When fully open, the center of the bloom shows brilliant golden yellow around the flower stamens. The petalage is double, ranging from twenty-five to thirty petals, with three to eight petaloids. The flower is highcentered in form at the first, and remains high-centered after opening fully. The bloom has a tea fragrance, from moderate to penetrating in strength. The plant sets hips freely, containing many seeds.

This invention relates to a new variety of floribnnda bush rose, tall and well adapted for outdoor cultivation and garden decoration.

The seed parent of this new variety is known as Spartan. The pollen parent was a cross of Goldilocks, with an unnamed variety produced by crossing :Fandango and Pinocchio. The plant holds its distinguishing characteristics through succeeding propagations by budding. It was originally propagated in Ontario, Calif.

Some of the ways in which this new variety dilfers from its seed parent. Spartan, are these: Spartan manifests a very vigorous, tall. growth, whereas the new variety is more branched and bushy: and is only moderately free growing, and comparatively less vigorous in its growth habit. The foliage of Spartan has a very characteristic drooping appearance, whereas the foliage of this new variety is carried at an attitude slightly above the horizontal, so as to give a more spritely appearance. The foliage of this new variety is of medium size, as compared to that of the Spartan rose, which is considerably larger. The leaves of the new variety are leathery in texture and semi-glossy in appearance. The flowers of the Spartan rose are described as very fragrant, whereas the flowers of the new variety have but a moderate fragrance. The color of the Spartan flower would be commonly referred to as reddish orange, whereas the flower of the new variety is much more orange, with a definitely yellow cast on the reverse side of the petals.

This new variety is distinguished from its unnamed pollen parent most notably in the following respects:- Whereas this new variety is moderately free and vigorous in growth, the pollen parent was moderately weak. The pollen parent only occasionally would produce a seed hip out of. doors, while this new variety, when grown under comparable conditions, will. produce many hips. The leaves of the pollen parent are quite soft, whereas the leaves of the new variety are somewhat leathery and somewhat moderately thin. The color of the pollen parent is a medium yellow, whereas the new seedling is a yellow and orange bicolor. The new variety blooms nearly continuously during the growing season, whereas the pollen parent bloomed intermittently during the season.

Plant Pat. 3,1fi2 Patented Apr. 11, 1972 The accompanying drawing illustrates the plant in color, and shows the flowering thereof from bud to full bloom. In the description which follows, the color values stated are based on the Nickerson Color Fan, except where the popular color designation is sutficiently descriptive for present purposes.

The flowers of this new variety are borne sometimes singly, but usually several to a stem in irregular clusters on normal short to medium stems. The plant blooms freely outdoors and nearly continuously during the grow ing season. The blooms have a moderate to penetrating tea fragrance.

As to the bud: The peduncle is of average length and of slender to average caliper. It is erect, usually smooth, and has some gland-tipped cilia. Its color is Moderate Olive, 7.5Y 4/3, overlaid with dark tones of Dark Red, 25R 3/7. Before the calyx breaks, the buds are of small size, moderately short and pointed in form, with foliaceous appendages, a few gland-tipped cilia, and glandular bloom on the surface of the bud, usually with slender foliaceous parts extending beyond the tip of the bud for a distance equal to about one-fourth or more of its length.

As the calyx breaks, the color presents shadings of Strong Red, 5R 4/12, and Dark Red, 5R 3/7, and some spotting of Moderate Yellow Green, 2.5GY 5/5. The inner surface of the sepals carries a fine wooly tomentum. Margins of alternate sepals are lined with stipitate glands and occasional slender foliaceous appendages. The margins of the other sepals are lined with stipitate glands and fine wooly tomentum.

As the first petal opens, it is small in size, short and ovoid in form. The outside of the petal displays a Brilliant Yellow, SY 9/9, in a small area at the base, which blends upwards through Moderate Orange Yellow, IOYR 8/10, to nearly Deep Yellowish Pink, 5R 6/11, at the apex. The inside of the petal shows a moderate area at the base which is Vivid Yellow, SY 8/12, ending abruptly at a portion colored nearly Strong Reddish Orange, 7.5R 5/13, with some Strong Reddish Orange, 7.5R 6/12, between the veins at the petal apex. The bud opens well and is not retarded or prevented from opening by cold, hot, wet or dry weather.

Bloom When fully open the bloom measures from 3 /2 to 4". The petalage is double, from 253() petals, plus 3-8 petaloids regularly arranged. It is high-centered in form, both at first and upon opening out. The petals at first are somewhat flat, with tips reflexed outward. Later, at maturity, they become somewhat more loosely flat, with tips reflexed outward. The petals are medium thick, slightly satiny on the inside, and shiny to satiny on the outside. The outer petals are broadly obovate, scalloped, but the apex is more rounded, although still having one or two notches. The inside petals are narrowly obovate, also being scalloped, with rounded apex and one or two notches.

The description which follows relates to the flower of a rose grown outdoors, newly opened in the month of April, in Ontario, Calif.

The color of the outside petal, on its outer surface, displayed a nearly Brilliant Yellow, 5Y 9/ 9, color in a moderate area at the base, with slight streaking of this color on the lower veins, blending into Moderate Orange Yel low, 7.5YR 8/ 8, and into nearly Strong Yellowish Pink, 5R 7/9. The inner surface of the outside petal displayed a moderate area at the base which was likewise nearly Brilliant Yellow, 5Y 9/ 9, which which yielded abruptly to a color between Strong Reddish Orange, 7.5R 6/12, and Strong Reddish Orange, 7.5R 5/13. The apex of the petal was nearly Strong Reddish Orange, 7.5R 6/ 12.

The outer surface of the intermediate petal was nearly Brilliant Yellow, Y 9/9, on a small area at the base, blending with Light Orange, 5YR 8/ 7, through the center of the petal and into nearly Strong Yellowish Pink, 5R 7/9, at the apex. The inner surface of the intermediate petal likewise had a small area at the base which was Brilliant Yellow, 5Y 9/9, yielding abruptly to a color between Strong Reddish Orange, 7 .SR 6/12, and Strong Reddish Orange, 7.5R 5/ l 3, for the remainder of the petal.

The outer surface of the inner petal again displayed a small area at the base which was nearly Brilliant Yellow, 5Y 9/9, blending and shading upwards through Light Orange, SYR *8/ 7, and into nearly Strong Yellowish Pink, 7.5R 7/9, at the apex. The inner surface of the inner petal had a moderate area at the base which was nearly Brilliant Greenish Yellow, 7.5Y 9/ 8, yielding abruptly to a color nearly Strong Reddish Orange, 7.5R 6/12, for the remainder of the petal.

The description which follows relates to the bloom of a rose plant grown outdoors in Ontario, Calif, after the flower had been open for three days in the month of April.

The outer surface of the outside petal showed a small area at the base which was Brilliant Yellow, 5Y 9/9, blending gradually with Moderate Orange Yellow, 7.5YR 8/ 8, and into Strong Pink, 2.5R 7/ 8. The inner surface of the outer petal showed a moderate area at the base which was nearly Vivid Yellow, SY 8/ 12, yielding abruptly to a color blending between Strong Yellowish Pink, 7.5R 7/ 9, and Strong Reddish Orange, 7.5R 6/12.

The outer surface of the inside petal showed a small area at the base and midrib partway up the petal colored a Brilliant Yellow, 5Y 9/ 9, shading to nearly Pale Orange Yellow, 7.5YR 9/ 4, and then into nearly Deep Pink, 2.5R 6/11, at the apex. The inner surface of the inside petal showed a moderate area at the base which was between Brilliant Greenish Yellow, 7.5Y 9/ 8, and Vivid Greenish Yellow, 7.5Y 8/12, the remainder being between Strong Yellowish Pink, 7.5R 7/9, and Strong Reddish Orange, 7.5R 6/ 12. The general color effect of the newly opened flower lies somewhere between Strong Reddish Orange, 10R 6/12, and Strong Reddish Orange, 7.5R 5/ 13. After the bloom had been three days open, the general color effect was between Strong Reddish Orange, 7.5R 6/12, and Deep Yellowish Pink, 5R 6/11. The petals drop off cleanly, except for the petaloids and the blooms are not affected by cold, hot, wet, or dry weather.
