ROSE PLANT Filed April 15, 1971 United States Patent US. Cl. Plt.--27 1 Claim ABSTRACT OF THE DISCLOSURE A floribunda rose of spreading and vigorous bushy growth, abundantly covered with medium-sized somewhat leathery and semi-glossy leaves, having peduncles of short to average length which are smooth except for numerous stipitate glands, the flower of said floribunda rose being characterized in that even from the opening of the bud the petals have pronounced apexes that are from acute to acuminate, seen especially on the outside and intermediate petals. The petalage of the freshly opened flower is double, comprising up to 45 petals and to 14 petaloids in a bloom measuring more than 3 inches but less than 4 inches in diameter. The coloration of the flower is predominantly medium salmon-pink.

This invention relates to a new rose plant of the floribunda class. The plant is a seedling of the outdoor bush type, cultivated for out flowers and for garden decoration. It was propagated by David L. Armstrong in Ontario, California, having as its seed parent Sumatra (Plant Patent No. 1,572) and, as its pollen parent, Circus (Plant Patent No. 1,382). It holds its distinguishing characteristics through succeeding propagations by budding.

The new variety bears its flowers usually two to five, or more, in regular clusters, on normal short to mediumlength stems. Sometimes, however, the flowers are borne singly. The plant blooms abundantly outdoors, and nearly continuously during the growing season. The bloom has a slight to moderate tea fragrance.

Among the differences between this new variety of rose plant and its seed parent, Sumatra, the following may be noted:

Although the plants of both offspring and parent are relatively spreading, the new variety is substantially taller and more floriferous than its seed parent, Sumatra, in plant size and habit.

This new variety has flowers popularly described as medium salmon-pink, whereas the flowers of its seed parent, Sumatra, would be described as signal-red.

The flowers of this new variety have from 35 to 45 petals, plus a number of additional petaloids, whereas the flowers of Sumatra have only 23 to 28 petals.

Among the differences between this new variety of rose plant and its pollen parent, Circus, the following may be noted:

This new variety of plant is distinctly spreading in habit, whereas the plant of Circus is essentially upright.

The semi-glossy leaves of this new variety are lighter green and of a somewhat more grayed hue than the leaves of Circus, which are very dark green and are glossy in surface appearance.

This new variety has peduncles which are characterized by numerous slender stipitate glands, but with no prickles, while the peduncles of Circus have both gland tipped cilia and prickles.

Whereas the bud and opening flower of this new variety are accentuated by acute to acuminate apexes of the petals, the petals of the Circus flower have no such pointed apex, their most prominent characteristic being a reflexing which gives the bud a definite urn shape.

The general color effect of flowers of this new variety Plant Pat. 3,392 Patented Feb. 13, 197 3 "ice is, as noted, medium salmonpink, whereas the flowers of its pollen parent, Circus, would popularly be described as yellow marked pink, salmon and scarlet.

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 short to average length and of average caliper, erect, and smooth except for numerous stipitate glands. The color is near Strong Yellow Green, SGY 6/8, overlaid with near Dark Red, 5R 3/7.

Before the calyx breaks, the bud is small to medium in size, of moderately short to medium-length, and usually pointed to ovoid in form.

As the calyx breaks, the color is between Strong Red, 5R 4/12, and Dark Reddish Orange, 7.5R 4/11.

The inner surface of the sepals carries a fine tomentum. The margins of alternate sepals are lined with fine tomenturn; margins of others usually have small foliaceous appendages. The tips of the sepals usually have very small foliaceous appendages.

On their outer surfaces the sepals have small stipitate glands.

As the first petal opens, it is small, short to mediumlength, and ovoid. The color on the outside of the petal is between Strong Purplish Pink, 7.5RP 7/10, and Deep Pink, l ORP 6/12. The color on the inside of the petal is near Deep Pink, lORP 6/ 12. The bud opens up well, and is not retarded or prevented from opening by cold, hot, wet, or dry weather.

Bloom When fully open, the bloom is average in size, being from 3% inches to 3% inches. The petalage is double, with from about 35 to 45 petals and usually with from 10 to 14 petaloids arranged irregularly. The bloom is full and high centered at first, with petals somewhat tightly cupped, with tips rolled outward. Later, at maturity, the petals become more loosely cupped, with tips rolled outward.

The petals are of medium thickness, very slightly leathery, the inside slightly satiny to velvety and the out side shiny to satiny. The outside petals are somewhat broadly obovate, with apex acute to acuminate. The intermediate petals are obovate, with apex acuminate and sometimes having one notch. The inside petals are obovate, sometimes irregularly scalloped, and usually with one notch. The colors may be modified by being shaded and/or washed with other colors.

The paragraphs immediately following describe color values observed in a flower newly opened in the month of September. The plant had been grown outdoors, in Ontario, Calif.

The outer surface of the outside petal was between Light Purplish Pink, SRP 8/5, and Strong Purplish Pink, 7.5RP 7/10. The inner surface of the outside petal was between Strong Purplish Pink, 7.5RP 7/10, and Strong Pink, IORP 7/8.

The outer surface of the intermediate petal was near Strong Purplish Pink, 7.5RP 7/10. The inner surface of the intermediate petal was between Strong Purplish Pink, 7.5RP 7/10, and Deep Pink, IORP 6/12.

The outer surface of the inner petal was between Strong Purplish Pink, 7.5RP 7/10, and Strong Pink, IORP 7/8. The inner surface of the inner petal was between Strong Pink, lRP 7/8, and Deep Pink, 10RP 6/12.

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

The outer surface of the outside petal was between Light Purplish Pink, SRP 8/5, and Light Purplish Pink, 7.5RP 8/5. The inner surface of the outside petal was between Strong Purplish Pink, 7.5RP 7/10, and Moderate Pink, 10RP 8/5.

The outer surface of the inner petal was between Light Purplish Pink, 7.5RP 8/5, and Strong Purplish Pink, 7.5RP 7/10. The inner surface of the inner petal was near Strong Pink, 10RP 7/8.

The general color eifect of the newly opened flower is near Deep Pink, 10RP 6/12. The bloom after being three days open gives a general color effect between Strong Purplish Pink, 7.5RP 7/10, and Strong Pink, lORP 7/8. The petals usually drop off cleanly, except for some petaloids. They are not particularly affected in this respect by cold, hot, wet, or dry weather.

The flower on the bush in the garden, in Ontario, Calif, persists from 3 to 5 days in the month of November. Cut roses grown outdoors and kept at living-room temperatures last up to five days in the month of November.
