ROSE PLANT Filed Nov. 17, 1972 United States Patent O 3,525 ROSE PLANT Walter E. Lammerts, Watsonville, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Calif. Filed Nov. 17, 1972, Ser. No. 307,425 Int. Cl. Atllh /00 Us. or. Plt.22 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to a new rose plant of the floribunda class. The plant is a seedling of the outdoor bush type, cultivated primarily for garden decoration. It was propagated by Walter E. Iammerts, at Livermore, Calif,

and grown at Ontario, Calif.

' Its seed parent, was Rumba (Plant Pat., No. 1,919) and its pollen parent Tropicana (Plant Pat. No. 1,969). It holds its distinguishing characteristics through succeeding propagations by budding. Its hardiness has not yet been determined. I

The new cultivar bears some flowers singly, but usually three or more to the stem in irregular clusters on strong short to medium-length stems. It blooms abundantlyoutdoors almost continuously during the growing season. The flowers have a moderate spicy fragrance;

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

The flower color of this new cultivar is pinkish-orange;

while that of Rumba .is poppy red'with' a yellow center according to Modern Roses. The new cultivar has sig-' nificantly more large and small prickles than does Rumba,

and the size of its flowers is slightly larger. The new cultivar bears flowers sometimes singly, but usually three or more to the stem; whereas the seed parent Rumba more frequently has more'than three flowers in a cluster. The average number of pistils in the new flower is 85; whereas with Rumba it is about 45.

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

The new variety characteristically bears its flowers in clusters and is of the floribunda class; while its pollen parent, Tropicana, characteristically bears its blooms singly and is of the Hybrid Tea class. The'new cultivar bears more flowers than its pollen parent Tropicana. The flower size of this neW'cultivar ranges. from 2%" to 2%" in diameter; whereas the flower size forTropicana is notably much larger, being generally about 5" in diameter. The flower color-of the new cultivar is pinkishorange, a color deeper and more intense than the coralorange of Tropicana. The fragrance of the new cultivar is moderate and spicy; whereas Tropicana is very fragrant and fruity in character. The plant of the new cultivar has a growth habit which is lower and more compact than the plant of Tropicana.

The accompanying drawing illustrates the plant in color, and shows the flowering thereof from bud to full bloom.

'Throu'ghout 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.

The peduncle is of average length and average caliper; It-- is erect, and has numerous stipitate glands and numerous tiny hairs. Its color is near Strong Yellow Green, 5GY6/8, lightly to heavily overlaid with near Dark Red, 2.5R3/7, where exposed to sunlight.

' Before the, calyx breaks, it is small to medium size, short to medium length, and ovoid. As the calyx breaks,

it has a color between Strong Reddish Orange, 7.5R5/ 13,

and Dark Red, 2,5R3/7, the darker'color being more prevalent.

The inner surface of the sepals carries a fine, wooly tomentum. Margins of alternate sepals have small foliaceous appendages and numerous. stipitate glands; margins of others have a fine, wooly tomentum. The outer surface of the sepals carries numerous stipitate glands and hairs.

As the first petal opens, it is average in size, medium in length, and ovoid to urn-shaped in form. The outside color of the petal is near Brilliant Greenish Yellow, 10Y9/,9, at the base, and ranging through near Strong Reddish Orange, 7.5R6/12, to near Dark Red, 2.5R3/7, as the petal received more light while the bud was opening. The petal on the inside had a color at the base near Brilliant Greenish Yellow, 7.5Y9/ 8, the main petal color being near but more vivid than Strong Reddish Orange, 10R6/12, and sometimes becoming near Strong Red, SR4/l2, irregularly near the margins.

The bud opensup well, and is not retarded, or prevented from opening, by cold, hot, wet, or dry weather.

' BLOOM When fully open, ,the bloom is from small to average in size for its class, being 2%" to 2%" in diameter. Its

petalage is double, with from 20 to 30 petals, plus 10 to 18 petaloids arranged regularly. It is high-centered at first, becoming open to cupped to high-centered. The petals remain cupped at first, with tips reflexed slightly .outward, becoming later, at maturity, more loosely I cupped, with tips reflexed outward.

' leathery, with inside satiny and outside slightly shiny to? PETALS The petals are of medium thickness, moderately satiny. The outside petals are nearly round, and are sometimes notched. The intermediate petals are obovate in form and are sometimes notched. The inside petals are from nearlyround to obovate to irregular, and are also sometimes notched. The colors may be modified by. being bordered, blotched, shaded .and/or washed with other colors.

The description which follows is of a newly opened flower in themonth of June, from a rose plant grown outdoors in Ontario, Calif;

The outside surface of the outside petal 'was near Bril-' liant Greenish Yellow, 10Y9/ 9, at the base, the remainder of the petal being between Deep Yellowish Pink, 5R6/ l1,

andDeep Pink, 2.5R6/1l. The inside surface of the outside petal was more vivid than, but ranged between Strong Reddish Orange, 10R6/l2, and Vivid Red, 5R5/ 13, with a portion at the base being near Brilliant Yellow, 5Y9/ 9.

The outside surface of the intermediate petal was near Brilliant Greenish Yellow, 7.5Y9/ 8 at the base, blending Patented Mar. 19., 1974 to near Strong Yellowish Pin-k, 10R7/ 9, in the middle of the petal, and becoming near Deep Yellowish Pink, R6/ 11, near the edges. The inside surface of the intermediate petal Wasnear Brilliant Greenish Yellow, 7.5Y9/ 8, near the base, the remainder being more vivid than, but between Strong Reddish Orange, R6/ 12, and Strong Reddish Orange, 7.5R6/ 12.

The inner petal was the same coloration as the intermediate petal, both inside and outside.

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

The outside surface of the outside petal was near Deep Pink, 10RP6/ 12, with a portion at the base being between off-white and Brilliant Yellow Green, 2.5GY9/8. The inside surface of the outside petal had a main petal coloration bet-ween Deep Yellowish Pink, 5R6/11, and

Deep Pink, 2.5R6/11, with a portion at the base the same color as the outside surface, at the base.

The outside surface of the inside petal was mainly between Strong Pink, 10RP7/ 8, and Strong Purplish Pink, 7.5RP7/10. The inside surface of the inside petal ranged from Strong Pin-k, 2.5R7/8, to a color between Vivid Red, 5R5/13, and Strong Red, 5R4/12. Both the outer and inner surfaces of the inside petal had a portion at the base which was between off-white and Brilliant Yellow, 5Y9/9.

The general color effect of a newly opened flower was near, but significantly more vivid than, Strong Reddish Orange, 10R6/l2. After being three days open, the color effect was near, but more vivid than, Vivid Red, 5R5/ 13.

The petals drop off cleanly, and are not particularly affected by cold, hot, wet, or dry weather. On the bush in the garden, blooms last from 4 to 5 days in the month of June. Cut roses grown outdoors and kept at livingroom temperatures last from 4 to 5 days in the month of June.
