ROSE PLANT 2 Sheets-Sheet I Filed Jan. 6, 1970 United States Patent I 3,076 ROSE PLANT David L. Armstrong, Upland, Califi, assignor to Armstrong Nurseries, lnc., Ontario, Calif. Filed Jan. 6, 1970, Ser. No. 1,066 Int. Cl. Alh /00 U.S. Cl. Plt.2 1 Claim ABSTRACT OF THE DISCLOSURE A climbing rose plant of the hybrid tea class, which is tall growing and has semi-glossy leaves of leathery texture, comprising three to seven leaflets of medium to large size; the flowers of said plant having a subdued fragrance and being of quite large size. The double petals are arranged regularly when fully open. The flowers are borne usually singly, but sometimes three or four, or even more, appear in irregular clusters on strong medium to long stems. The plant is free blooming outdoors, and blooms nearly continuously during the growing season. Its habit of growth is notably vigorous, tall, upright and branching.

This invention relates to a new variety of climber rose plant of the hybrid tea class. The plant is tall-growing in habit and is well adapted to outdoor cultivation both for cut flowers, and for garden decoration.

The plant, a seedling bred by crossing Buccaneer (P.P. No. 1,119) as the seed parent with Bravo (P.P. No. 983) as the pollen parent, holds its distinguishing characteristics through successive propagations by budding. It was originally propagated in Ontario, Calif.

The new variety is distinguished from its seed parent, Buccaneer, in the following respects: Whereas, Bucaneer is a grandiflora rose, the present variety is a climbing hybrid tea rose; whereas the flowers of Buccaneer are popularly described as buttercup yellow in color, the flowers of the new variety are purplish red. Whereas Buccaneer flowers are relatively small in size, the flowers of the present variety are about 2" larger. Whereas Buccaneer flowers are cupped in form, the new variety is high-centered when open, giving an exceptionally good formal effect. Whereas Buccaneer is moderately fragrant, the fragrance of the new variety is relatively quite subdued.

The new variety is distinguished from its pollen parent, Bravo, in the following ways: Whereas Bravo is a bush rose of the hybrid tea class, this new variety has a climbing habit of growth. Whereas the flower of the Bravo rose is popularly described as cardinal red in color, the flower of this new variety is lighter purplish red. Both flowers are double, but Bravo has more than 35 petals, whereas the new variety has fewer, usually from 25 to 30. The flowers of Bravo usually range from 4" to 5", whereas the new variety is somewhat larger, often 5 /2". Whereas the Bravo rose sets very little seed outdoors under normal garden conditions, this new variety sets seed very readily by natural means when raised in Ontario, Calif.

FIG. 1 of the accompanying drawings shows the flowering of the plant in color, from bud to full bloom. FIG. 2 shows the plant in black and white, illustrating its extremely vigorous growth habit.

The flowers of the new variety, as observed in Ontario, Calif, are usually borne singly, on strong medium to long stems, but sometimes appear in irregular clusters of three or four. The plant blooms freely outdoors and almost continuously during the growing season. The fragrance is slight to moderate.

In the description which follows, the color values stated conform to the Nickerson Color Fan.

Plant Pat. 3,076 Patented Oct. 19, 1971 ICC Bud

As to the bud: the peduncle is of average length, of average caliper, and erect. The peduncle may have several to many stipitate glands, and may have a few small prickles, or none at all. Its color is near to Strong Yellow Green, 5GY6/ 8, overlaid with near Moderate Yellowish Brown, 10YR4/4 on the side exposed to the sun.

Before the calyx breaks, the bud is of medium size, short to medium length, and of ovoid form, with foliaceous appendages and some glandular bloom on the surface of the bud, the foliaceous parts extending beyond the tip of the bud for a distance equal to about one-half of its length, or slightly more.

As the calyx breaks, the color is between Strong Red, 5R4/ 12, and Moderate Red, 2.5R4/l0. A fine, Wooly tomentum covers the inner surface of the sepals, and lines the margins of alternate sepals; margins of other sepals have from few to several small stipitate glands and small slender foliaceous parts. The sepals sometimes have foliaceous appendages extending for a distance equal to from one-fourth to one-third of the length of the sepal. The outside surface of the sepals is usually provided with from a few to several small stipitate glands.

As the first petal opens, the bud Will be of average size, medium length, and ovoid form, usually progressing to urn-shaped. The color outside will approach Strong Purplish Red, 7.5RP5/12, in the upper area, blending with near Strong Yellowish Pink, 5R7/9, toward the base of the petal; the small area at the base of the petal will be near Vivid Yellow, 5Y8/12. The inside color will be near Strong Purplish Red, l0RP4/l2, blending with near Deep Yellowish Pink, 5R6/11, toward the base of the petal. The small area at the base of the petal will be near Greenish Yellow, 7.5Y8/12. The bud opens up well and it is not retarded or prevented from opening by cold, hot dry, or wet weather.

Bloom The bloom when fully open is of large size, usually from 5 to 5%." in diameter. The petalage is double, and the bloom comprises from 25 to 30 petals, plus 5 to 10 petaloids, in regular arrangement. Its form is high-centered at first, later becoming fiat or slightly cupped. The petals at first are tightly cupped, with the tips rolled outward. At maturity, they are somewhat less tightly rolled.

Petals The petals are medium thick in texture, and moderately leathery, with a satiny surface both inside and outside. The outside petals are between round and broadly obovate in form, with apex fiat, and usually with 2 to 3 notches. The intermediate petals are broadly obovate, with apex rounded, sometimes with 1 or 2 notches. The inside petals are likewise broadly obovate. The colors may be modified by being shaded and/or washed with other colors.

The following description is of the newly opened flower of a rose grown outdoors in the month of October, in Ontario, Calif:

The outer surface of the outside petal is near Deep Purplish Pink, 7.5RP6/ l2, blending with near Deep Pink, 2.5R6/1l. The small area towards the base of the petal is near Vivid Greenish Yellow, 7.5Y8/ 12. The inside surface of the outside petal is near Strong Purplish Red, 1ORP4/l2, blending with near Deep Yellowish Pink, 5R6/11, toward the base of the petal. The small area at the base of the petal is near Vivid Yellow 5Y8/12.

The outer surface of the intermediate petal is near Moderate Pink, 5R8/ 6, blending with near Light Orange, 5YR8/ 7, toward the base of the petal. The small area towards the base of the petal is near Vivid Yellow, 5Y8/ 12. The inside surface of the intermediate petal is near Strong Purplish Red, 10RP5/12, blending with near Deep Yel- 3 lowish Pink, 5R6/11, toward the base of the petal. The small area towards the base of the petal is near Vivid Yellow, 5Y8/12.

The outer surface of the inner petal is near Moderate Yellowish Pink, R8/6, blending with near Moderate Orange Yellow, 7.5YR8/8 toward the base of the petal. The small area towards the base of the petal is near Vivid Yellow, 5Y8/12. The inside surface of the inner petal is near Strong Red, 2.5R5/l2, blending with near Strong Reddish Orange, 7.5R6/ 12, toward the base of the petal. The small area towards the base of the petal is near Vivid Yellow, 5Y8/ 12.

The following description is of a flower of the new variety that has been open for three days outdoors in the month of October in Ontario, Calif.:

The outer surface of the outside petal is near Deep Purplish Pink, 7.5RP6/12. The small area towards the base of the petal is near Brilliant Yellow, 5Y9/ 9. The insidesurface of the outside petal is between Strong Purplish Red, 7.5RP5/12, and Deep Purplish Pink, 7.5RP6/12. The small area towards the base of the petal is near Vivid Greenish Yellow, 7.5Y8/12.

The outer surface of the inside is near Moderate Pink, 2.5R8/5, blending with near Light Yellowish Pink, 2.5YR9/ 3 toward the base of the petal. The small area towards the base of the petal is near Brilliant Greenish Yellow, 7.5Y9/ 8. The inside surface of the inside petal is near Strong Purplish Red, 10RP5/ 12, blending with near Deep Pink, 2.5R6/11, toward the base of the petal.

The general color effect of the bloom as a whole lies between Strong Purplish Red, 10RP5/ l2, and Strong Purplish Red, 10RP4/ 12, when the flower is newly open. Three days later, the general effect will lie between Strong Purplish Red, 7.5RP5/ 12, and Strong Purplish Red, 10RP5/ 12.

The petals drop off cleanly. They are not particularly affected by cold, hot, wet, or dry weather.

Flowers on plants in the garden will last from three to four days in the month of November, in Ontario, Calif. Cut roses grown outdoors and kept at livingroom temperatures will last from two to three days in the same locale and during November.
