AFB/ 138 Int. Cl. A01h 5/00 US. Cl. Plt.20 1 Claim ABSTRACT OF THE DISCLOSURE A hardy spreading bush rose of the floribunda class characterized primarily by striking color diiference between margins and centers of the flower petals, the margins being distinctly pale, particularly where the plants are grown in areas of low light intensity, the plant being of the spreading type, thickly branched, displaying new leaves with an inconspicuous raised dark green area, the peduncles, although otherwise smooth, having a number of very small short stipitate glands.

This invention relates to a new rose plant of the floribunda class. The plant is a seedling of the hardy, spreading bush type, cultivated primarily for garden decoration.

Although the new variety was originally propagated in Portadown, County Armagh, Northern Ireland,,.the description which here follows was made from a plant budded and grown in Ontario, Calif., from the Irish stock.

The seed parent of this new variety was Marlena, the pollen parent being an unnamed seedling which was derived by crossing Evelyn Fison (0range Sweetheart Fruhlingsmorgen). The plant holds its distinguishing characteristics through succeeding propagations by budding.

This new variety usually bears its flowers singly, on normal strength, short stems. Sometimes, however, the flowers are borne in irregular rounded clusters of three to five, or more, to a stem. The plant blooms freely outdoors, and nearly continuously during the growing season. The bloom has a slight fragrance.

The differences between this new variety of rose plant and its seed parent, Marlena, include the following features:

The flowers of Marlena would normally be described as dark red, but the new cultivar displays a variety of shades of red and is particularly distinguished by the variation in color between the inner portion of the bloom and the outer petals. Furthermore, the margins .of the petals of the new variety contrast with the color of the center, particularly if grown in areas of low light density, such as Northern Ireland.

The plants of Marlena are low growing and somewhat spreading, but they are not as vigorous, as spreading, or as thickly branched as plants of the new cultivar. Most of .the flowers of the new cultivar are borne on single stems, whereas the seed parent bears a larger proportion of its blooms in clusters.

The juvenile leaves of this new cultivar have inconspicuous but nevertheless discernible dark green raised spots, which are not found in the foliage of Marlena at any stage of its growth. This new cultivar has many more large prickles and somewhat more small prickles than its seed parent, and these prickles are smaller and more slender in their proportions, both as to base and length, than Marlenas prickles.

The stems of this new variety are shorter and stiffer than the characteristic stems of the Marlena cultivar.

The differences between this new cultivar and its pollen parent, Evelyn Fison (Orange SweetheartXFruhlingsmorgen), include the matters stated below:

Plant Pat. 3,351

The flowers of this new cultivar are semi-double and their color system is quite unique. The cultivar Evelyn Fison has scarlet flowers which are double in petalage, whereas the new cultivar petalage is only semi-double. In the new cultivar, the cluster of flowers is usually small, whereas the clusters of Evelyn Fison are broad. Indeed, the entire plant of this new cultivar is substantially larger than the plants of the Evelyn Fison rose, and much more thickly branched.

The color of the flowers of this new variety, and the petalage of it, are quite different from Orange Sweetheart. Further, this new cultivar is a much more vigorous plant, more denselyv branched and more spreading in habit than isthe cultivar Orange Sweetheart.

As compared to the .remaining member of the group, the cultivar Fruhlingsmorgen is classifiedv as a shrub rose, whereas the new variety is a floribunda. The habit of these plants is strongly diiferent. The new cultivar is thickly branched: and dense, with abundant foliage covering, while. the plants of Fruhlingsmorgen are rangy and tall in habit and tend to be rather sparsely provided with foliage. Also, this new cultivar has flowers which are semidouble in petalage, whereas Fruhlingsmorgen has flowers which are characteristically single, and have five petals. Further, this new .cultivar seldom .sets hips, and when it doestheydo not persist. The cultivar Fruhlingsmorgen, on the other hand, sets hips freely, which persist and are very colorfuL.

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, slender to average caliper, erect, and usually smooth, but with several to many small stipitate glands. Its color is near Light Olive, 10Y 5/5, overlaid with near Moderate Yellowish Brown, 10YR 4/4, on the side exposed to the sun.

Before the calyx breaks, the bud is small, short and ovoid in form.

As the calyx breaks, the color is near Dark Red, 2.5R 3/ 7. The innersurface of the sepals carries a fine, woolly tomentum.

The margins of alternate sepals are lined with a fine, woolly tomentum', margins of others are lined with many small stipitate glands and small slender foliaceous parts. The outside surface of the sepals is usually smooth, with from'none' to few small stipitate glands. Usually,- the foliaceous parts extend to one-third of the sepal length.

As the first petal opens, the bud is small, short, and ovoid in form. The color. on the outside of the petal is near Strong Red, 5R-4/12.'The inside surface of the petal is between Vivid Red, 5R 5/13, and Strong Red, 2.5R

.5/ 12. The bud opens up well, and is not retarded or prevented fromopening by cold, 'hot,.wet, or dry weather.

Bloom Atfirstthe petals are loosely cupped, becoming later at maturity loosely. flat. They are of medium thickness,

moderately leathery, with inside slightly velvety and outsidesatmy. The outsidepetals are between round and 3 broadly obovate, with "apex flatIThe intermediate petals are broadly obovate, with apex rounded. The inside petals are obovate, also with apex rounded. The colors maybe 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 October. The plant had been grown outdoors in Ontario, Calif.

The outer surface of the outside petal is near Moderate Red, 2.5R 4/ 10. The inner surface of the outside petal is between Moderate Red, 2.5 4/10, and Strong Red, 5R 4/ 12.

The intermediate and inner petals are the same in coloration, being near Strong Purplish Pink, 7.5RP 7/10, on the outer surface and between Moderate Red, 2.5R 4/ 10, and Strong Red, 5R 4/ 12, on the inner surface.

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

The outer surface of the outside petal was between Strong Purplish Red, RP 4/12, and Strong Purplish Red, 7.5RP 4/11. The inner surface of the outside petal was near Strong Purplish Red, 10RP 4/12, with approximately one-fifth of the petal width in the area along the edges and apex of the petal being near Deep Purplish Pink,

The outer surface of the inside petal was'near Light Purplish Pink, SRP 8/5. The inner surface of the inside petal was between Strong Red, 5R 4/12, and Moderate Red, 2.5R 4/ 10, with approximately one-fifth of the petal width in the area along the edges and apex of the petal being near Deep Purplish Pink, 7.5RP 6/12.

The general color effect of the newly opened flower is between Moderate Red, 2.5R 4/ 10, and Strong, Red, 5R 4/12. The bloom after being three days open gives a general color effect of from Moderate Red, 2.5R 4/10 to Strong Purplish Red, 10R 4/12. The petals drop ofi cleanly, and are not particularly affected in this respect by cold, hot, wet, or dry weather.

The flower on the bush in the garden persists for from three to five days in the month of November, in Ontario,

Calif. Cut flowers grown outdoors and kept at living-room temperatures persisted for two to three days in the month of November.
