ROSE PLANT Filed April 15. 1971 United States Patent 3,322 ROSE PLANT David L. Armstrong, Upland, Calif., assignor to Armstrong Nurseries, Iuc., Ontario, Calif. Filed Apr. 15, 1971, Ser. No. 134,517 Int. Cl. A01h /00 US. Cl. Plt.15 1 Claim ABSTRACT OF THE DISCLOSURE A hybrid tea rose plant which bears large yellow blooms on long, strong stems. Most stems bear a single bloom, though some may bear three or four in an irregular cluster. The flower may span as much as 5 inches when fully opened, and may contain as many as forty petals. The plant blooms freely outdoors almost continuously during the growing season. The general effect of the newly-opened flower is almost pure rich yellow, with little if any other coloration.

The invention relates to a new class of hybrid tea rose. The plant is a seedling of the tall bushy outdoor type, cultivated for cut flowers primarily and for garden decoration. It was propagated by David L. Armstrong in Ontario, Calif., having as its seed parent High Time and, as its pollen parent, Imperial Gold. It holds its distinguishing characteristics through succeeding propagations by budding.

The new variety bears its flowers usually singly on strong long stems. Sometimes three or four blooms may be carried on one stern, however, in an irregular cluster. The plant blooms freely outdoors, and almost continuously during the growing season. It has a moderate tea to spicy fragrance.

This new variety of rose plant differs from its seed parent, High Time, in the following particulars:

The color of the new variety is predominantly brilliant yellow, both in the bud and in the opening flower, but sometimes displays a slightly greenish hue. The seed parent, in contrast, is of claret-rose color, with reverse of gold and pink.

The fragrance of the new variety is a moderate tea to spicy odor; the seed parent, on the other hand, is very fragrant, of a spicy odor.

The flowers of the new variety have from 35 to 40 petals arranged about 5 to 15 petaloids, whereas the flowers of its seed parent typically had 18 to 28 petals.

The habit of growth is more vigorous with the new variety than with High Time, even though High Time should itself be rated as a very vigorous grower.

The peduncles of the new variety are characteristically smooth, except for a few scattered glands, whereas the peduncles of High Time are typically covered with numerous small prickles and stipitate glands of varied sizes.

The new variety is distinct from its pollen parent, Imperial Gold, in the following particulars:

The habit of growth of the new variety is substantially more erect than that of Imperial Gold, which is substantially more spreading, even though it is not extreme in its spreading habit.

The color of the petaloids in the new variety is more or less uniformly yellow, whereas in the flowers of the pollen parent the petaloids are strongly marked with scarlet or near crimson on many individual petaloids.

The flowers of the new variety range from 4 /2 to 5 /2 inches, whereas those of Imperial Gold are generally smaller, ranging from 3 /2 to 4 /2 inches. Furthermore, the flowers of the new variety, as previously noted, contain from 35 to 40 petals with 5 to 15 petaloids, whefeas the flowers of the pollen parent have only 30 to 35 petals.

The flower-bearing stems of the new variety are very Plant Pat. 3,322 Patented May 1, 1973 long, whereas those of the pollen parent are shorter even though sturdier.

The new variety rarely sets hips, whereas the pollen parent, Imperial Gold, sets hips rather freely under garden conditions.

The internodes on this view variety are substantially longer than those of Imperial Gold.

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 long and of heavy caliper, being erect and usually smooth. The color is near Strong Yellow Green, SGY 6/8, overlaid with near Moderate Yellow Green, 2.5GY 5/5, in areas exposed to the sun.

Before the calyx breaks, the bud is medium to large in size, of medium to long length, is pointed and ovoid in form.

As the calyx breaks, the color is between Brilliant Greenish Yellow, 7.5Y 9/8, and Brilliant Yellow, 5Y 9/9. The inner surface of the sepals carries a fine, woolly tomentum.

The margins of alternate sepals are lined with a fine woolly tomentum; margins of others with several to many small stipitate glands and small slender foliaceous parts.

The outside surface of the sepals is usually smooth.

The sepals are usually with foliaceous appendages extending to one-half or more of sepal length.

As the first petal opens, it is average to large in size, of mediumlength, ovoid, and usually urn-shaped. The color on the outside of the petal is near Brilliant Yellow, 2.5Y 9/9. The inside surface of the petal shows near Brilliant Yellow, 5Y 9/9, blending with near Vivid Yellow, 5Y 8/12 toward the base of the petal. The bud opens up well and is not retarded or prevented from opening by cold, hot, wet or dry weather.

Bloom The size Otf the bloom when fully open is average to 7 large, ranging from 4 /2 to 5 /2 inches. The petalage is double, with from 35 to 40 petals arranged regularly plus 5 to 15 petaloids. The bloom is high centered at first, becoming cupped to high centered.

At first the petals are tightly cupped, with tips reflexed outward, becoming later at maturity loosely flat to cupped, with tips reflexed outward.

Outside and intermediate petals of the newly opened flower are usually reflexed outward, both along the apex and the edges. All petals on a three-days open flower are usually reflexed slightly outward, both along the apex and the edges.

The petals are of medium thickness, and are satiny in texture, both inside and outside. The outside petals are broadly obovate, with apex flat, and sometimes with l to 2 notches. The intermediate petals are also obovate, but with apex rounded, and sometimes with 1 or 2 notches. The inside petals also are obovate, with apex rounded. 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 is near Brilliant Yellow, 2.5Y 9/9, blending with near Brilliant Greenish Yellow, 7.5Y 9/ 8 toward the base of the petal. The inner surface of the outside petal is near Brilliant 3 Yellow, Y 9/9, blending with near Brilliant Greenish Yellow, 7.5Y 9/ 8 toward the base of the petal.

The outer surface of the intermediate petal is near Brilliant Yellow, 2.5Y 9/9, blending with near Brilliant Greenish Yellow, 7.5Y 9/8, toward the base of the petal. The inner surface of the intermediate petal is-near Brilliant Yellow, 5Y 9/ 9, blending with near Vivid Greenish Yellow, 7.5Y 8/12, toward the base of the petal.

The outer surface of the inner petal is near Brilliant Yellow, SY 9/ 9. The inner surface of the inner petal is near Brilliant Yellow, 5Y 9/ 9, blending with near Vivid Yellow, SY 8/12, toward the base of the petal.

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

The outer surface of the outside petal was between Brilliant Yellow, 5Y '9/9, and Brilliant Greenish Yellow, 7.5Y 9/8. The same color values characterized the inner surface of the outside petal.

The outer surface of the inside petal was between Brilliant Yellow, 5Y 9/9, and Brilliant Greenish Yellow, 7.5Y 9/ 8. The same color values characterized the inner surface of the inside petal.

The general color effect of the newly opened flower is between Vivid Yellow, 2.5Y 8/12, and Brilliant Yellow, SY 9/9. The bloom after being three days open gives a general color effect which is between Brilliant Yellow, 5Y 9/9, and Brilliant Greenish Yellow, 7.5Y 9/8. The petals drop off 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 3 to 4 days in the month of August, in the locality named. Cut roses grown outdoors and kept at living-room temperatures will last from 2 to 3 days in the month of August.

Reproductive organs Stamens: The stamens are average in number, regularly arranged about the pistils, a few of them being mixed with petaloids.
