Filed Oct. 13, 1972, Ser. No. 299,912 Int. Cl; A01h /00 US. Cl. Plt.24 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of rose plantof the, Floribunda class, having a tendency. to flower heavily. andto bear many of its blooms singly, on relatively straightstems which are. valuable for cuttingbecause of; their length andicaliper. Blooms have, a strongspicy. fragrance, are brilliant yellow in color as they open, and fade only slightly after opening. Stemshavevery-few thorns andprickles, and peduncles are almost free of stipitate glands. The planthas better than average resistance. to mildew. Its blooms are large for the class, andthey range from 2 /2 to 3 /4 inches in diameter with from 30 to 50 petals plus 2 to .6 petaloids. The petals are undulateddnyform throughout the life of the bloom.

This invention relates to a new variety of rose-of the floribunda class. It is aseedling of the bush type, grown in the greenhouse, for cut flowers. It was discvovered and invented by. Arnold W. Ellis and Herbert C. Swim, ofUpland and Ontario, Calif, respectively. Its-seed parent is Gold Strike (Plant Pat. No. 1,435) and-its pollen parent Golden Garnette (Plant Pat. No. 1,898). The new cultivar holds its distinguishing characteristics throughsucceeding propagations by budding.

The plant presently. described was grown in a five-gallon container in a greenhouse at Ontario, Calif. It usually bears its blooms singly, although sometimes two or three to a stem, on strongmediumto long stems. The bloom is abundant in the greenhouse, and is nearly continuousthroughout the growing season; The fragrance is strong and spicy.

The new cultivar differs from its seed parent, Gold Strike, in several ways, including the following:

It bears its blooms singly more often, and in clusters significantly less often, thandoes Gold Strike. The petals of the new cultivar are'wider in relation-to their length,

that. is, they are, more broadly. obovate than petals of1 Gold Strike.

The new cultivar has very few large or small/prickles on its stems and branches,whereasonGold Strike, there are several long and sharp prickles on its mainstems and branches.

The new cultivar has no stipitate glands and few hairs on its peduncles, whereas Gold' Strike has many stipitate glands and manyhairson itspeduncles.

The flowers of the new cultivar are, on the average, somewhat larger than the Gold Strike parent, the latter being normally 2 to 2 /2 inches in diameter, Whereas the new cultivar will range from 2 /2 to 3% inches in diameter when grown under favorable conditions as described.

The new cultivar characteristically has about 80 pistils on the average, whereas Gold Strike usually has only about 60 pistils per flower.

The new cultivar differs from its pollen parent, Golden Garnette, in several ways, including:

The plant has stems which are notably straighter and longer than the stems of Golden Garnette, and carries fewer large prickles on its stems and branches than Golden Garnette. Furthermore, the peduncles of the new rose characteristically have fewer hairs than those of Golden Garnette, which may have many hairs.

Plant Pat. 3,518 Patented Mar. 12, 1974.

The, flowers of the new cultivar are more fragrant than the flowers of Golden. Garnette and, although they fade somewhat at the margins,,significantly less fading occurs on the petals of the new cultivar than on.the petals of- Golden Garnette. The number of pistils in flowers of the new cultivar averages aboutl80, whereas GoldenGarnette will have about 50 pistils per flower, whenlgrown under comparable conditions.

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 signifythattheiname of that color, as:

used in common speech,- is-aptly descriptive. Color names beginning with a capital letter designate values based upon The peduncle is of average; length-and average caliper. It is erect andjalmostsmooth, with some hairs. Itscolor is near Strong Yellow Green, 5GY6/8.

Before the calyxbreaks, it is small to medium size, for its class, short to, medium-length, pointedand ovoid. As the calyx breaks, it'has acolor; ranging fromnear Brilliant Yellow, 2.5Y9/9, to near Vivid Yellow, 2.5Y8/12.

The inner surface of the sepals carries a fine tomentum, the margins of alternate sepals being lined, with a fine. wooly tomentum, whilethe margins of others have some stipitate glands and afew small, narrow foliaceous ape pendages; sepal apices sometimes have small foliaceous parts; outer surface of sepals is relatively smooth.

As the first petal opens, it is average, in size for this class, short to medium-length, and urn-shaped. Its color on the outside is near Vivid Yellow, 5Y8/12, becoming lighter near its-apical margin to a. color near Brilliant Yellow, 5Y9/9. The inside coloration isthe same as the outside surface.

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

BLOOM When fully open, the bloom is largevin size, beingfrom 2 /2 to 3% inches indiameter. Its petalage is double, with from 30 to 50 petals, plus 2 to 6 petaloids arrangedregularly. In form, it is cupped to high centered at first, be-v coming open to cupped to high centered. At first, the petals remain cupped, with tips reflexed outward; later, at maturity, they aresomewhatmore loosely cupped, with-tips refiexed outward. Petals areundulatedthroughout the life ofthebloom.

PETALS The petals are of medium thickness, with both inner andouter surfaces slightly shiny to satiny. Theoutside petals are nearly round-to broadly obovate. The intermediate petals are broadly obovate to obovate. The inside petalsarebroadly obovateto irregular. All petals are undulatedthroughout the life of the bloom. The color may be modified by fading slightly and gradually.

The description which follows is of a rose that was newly opened in the month of June, from a rose plant grown in a five-gallon can in a greenhouse, in Ontario, Calif:

The outer surface of the outside petal was between Brilliant Yellow, 2.5Y9/ 9, and Brilliant Yellow, 5Y9/ 9. On the inner surface of the outside petal, there was an area at the base which was near Vivid Yellow, 5Y8/l2, while the remainder of the inner surface was between Brilliant Yellow, 2.5Y9/ 9, and Vivid Yellow, 2.5Y8/l2.

The outer surface of the intermediate petal was between Brilliant Yellow, 2.5Y9/9, and Brilliant Yellow, 5Y9/ 9. The inner surface of the intermediate petal had an area at the base which was near Vivid Yellow, 5Y8/ 12, the

3 remainder being between Brilliant Yellow, 2.5Y9/9, and Brilliant Yellow, Y9/ 9.

The outer surface of the inside petal was the same coloration as the outer surface of the outside petal, while the inner surface of the inside petal was the same as the inner surface of the intermediate petal.

The description which follows is of a rose that was open for three days in the month of June, having been grown in a greenhouse in Ontario, Calif:

Both the outer surface and the inner surface of the outside petal had an area at the base which was near Vivid Greenish Yellow, 7.5Y8/ 12, while the remainder was a pale yellow color which was lighter than Brilliant Yellow, 5Y9/ 9, but in the same hue.

The inside petal was the same color, on both inner and outer surfaces, as the outside petal.

The general color effect of a newly opened flower was between Brilliant Yellow, 2.5Y9/9, and Vivid Yellow, 2.5Y8/l2. After being three days open, the color effect was a pale yellow, lighter than Brilliant Greenish Yellow, 7.5Y9/ 8.

The petals drop off cleanly, except for petaloids, and are not particularly affected by cold, hot, wet, or dry weather. On the bush in can in the greenhouse, blooms last from 4 to 5 days in the month of June. Roses cut from plants grown in the greenhouse and kept at livingroom temperatures last from 3 to 5 days in the month of August.

REPRODUCTIVE ORGANS Stamens: Average in number, arranged regularly about the pistils, a few being mixed with petaloids.

Filaments: Short to medium-length, being from 7 to A" long. They are near Brilliant Greenish Yellow, 7.5Y9/8, almost always without red over-casting, and

most with anthers.

Anthers: Small to medium in size, all opening approximately at once. On the upper side they are near Brilliant Yellow, 5Y9/ 9, with margins near Strong Orange Yellow, 7.5Y7/11. On the under side of the coloration is the same as the upper side.

Pollen: Moderate in amount, and near Strong Orange Yellow, 7.5YR7/11, in color.

Pistils: Average in number, approximately 80.

Styles: From even to uneven, of average length, thin in caliper, and loosely bunched.

Stigma: Near Brilliant Yellow, 2.5Y9/9, in color.

Ovaries: Both enclosed in and protruding from the calyx.

Hips: None available.

'FOLIAGE Leaves are compound, usually 3 to 7 leaflets. They are normal to abundant, medium size, moderately heavy to somewhat leathery, and semi-glossy. Leaflets are nearly round to ovate, with apex mucronate, base obtuse, and mar-gin irregularly serrate.

The color of the mature leaf on the upper surface is between Moderate Olive Green, 5GY4/3, and Grayish Olive Green, 5GY3/2. The under surface of the mature leaf is grayer than a color between Strong Yellow Green, 2.5GY6/8, and Moderate Yellow Green, 2.5GY5/5.

The color of the young foliage on the upper surface is near Strong Yellow Green, 5GY6/ 8, moderately overlaid with near Moderate Reddish Brown, 7.5R3/6, near the margins. The under surface is between Strong Yellow Green, 5GY7/10, and Strong Yellow Green, 5GY6/8, lightly overlaid along the margins with near Dark Red, 2.5R3/7.

The rachis is light to average size, the upper side being grooved, with some stipitate glands on the edges, the under side being sometimes smooth or with stipitate glands, or sometimes slightly prickly and with stipitate glands.

The stipules are medium-length, moderately narrow, with medium-length narrow points turning out at an angle of less than 90.

The plant exhibits more than average resistance to mildew, when compared to other varieties now in commerce, and grown under equivalent conditions.

In growth habit, the plant is bushy, upright, and much branched. Its growth is very vigorous, and its canes are of medium caliper.

The main stems are near Moderate Yellowish Green, 7.5GY5/ 7, much-streaked with between Brownish Orange. SYRS/ 8, and Strong Brown, 5YR4/5. There are a very few large prickles, and these are short to medium-length, almost straight, and with moderately short, moderately narrow base. Their color is between gray and Strong Brown, 5YR4/5. There are a very few small prickles, and these are the same color as the large prickles. There are no hairs.

The branches are between Moderate Yellow Green, 5GY5/ 6, and Moderate Olive Green, 5GY4/3. There are a very few large prickles which are almost straight, with moderately short, moderately narrow base. They are between Strong Yellowish Brown, 10YR5/6, and Moderate llitrown, 7.5YR4/5. There are no small prickles and no airs.

The new shoots are between Strong Yellow Green, 5GY7/ 10, and Strong Yellow Green, 5GY6/8. There are usually no prickles, large or small, and no hairs.

We claim:

1. A variety of rose plant of the floribunda class substantially as herein shown and described comprising in combination a plurality of the following characteristics, namely, a vigorous habit of growth, a tendency to carry many of its blooms singly, on relatively straight and long stems which are relatively free of thorns and prickles; the strong, spicy fragrance; the brilliant yellow of the freshlyopened bloom, with less than usual fading as the flower matures; the blooms being from 2 /2 to 3% inches in diameter when grown under favorable conditions in Southern California, and comprising from 30 to 50 petals, all undulate, and from 2 to 6 petaloids, with about pistils per bloom; the plant displaying somewhat better than average resistance to mildew under comparable conditions.
