May 29, 1973 ARMSTRONG Plant Pat. 3,348

ROSE PLANT Filed Sept. 50, 1971 United States Patent US. Cl. Plt.15 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of rose plant of the Hybrid Tea class, of medium to tall growth habit, vigorous and much branched, with strong moderate length upright stems, usually each bearing only one bloom. The peduncles are unusually strong, and each will hold a fully opened flower in upright position, even though the flowers are relatively large, measuring from 4 /2" to 7" in diameter.

The buds have foliaceous appendages extending beyond the tip a distance equal to from one-third to full bud length. As the bud opens, the outer surface of the petals displays a deep golden yellow color, heavily overlaid with a strong orangish-red.

The general color effect of the fully opened flower is a creamy yellow, with light orangish-pink overtones. There are from 30 to 40 petals, with 10 to 16 petaloids.

A particularly desirable characteristic is the relative longevity of the flowers, when grown outdoors. on the bush, they last from 5 to days in moderately cloudy weather in southern California. As cut flowers, at livingroom temperatures, they will last for from 4 to 7 days. The flower has a pleasing moderately strong fragrance.

This invention relates to a new variety of hybrid tea rose, of the tall, bush type, grown as an outdoor plant for out flowers and garden decoration. It was propagated and grown in Ontario, Calif.

The plant is a seedling having as its seed parent Manitou, and as its pollen parent Summer Sunshine (Plant Patent 2,078). It holds its distinguishing characteristics through suceeding propagations by budding.

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

This new variety may be distinguished from its seed parent, Manitou, in the following characteristics:

The plant of this new variety is taller and more vigorous than the plant of Manitou. The stems of this new variety have more small prickles, especially on the lower onefourth to one-third of their length, than do the stems of Manitou.

The leaves of this new variety are not as resistant to damage from mildew, however, as the leaves of Manitou. The mature leaflets and leaves of this new variety are generally smaller than the mature leaflets and leaves of Manitou, and have a duller appearance than the leaves of Manitou, which are glossy.

The underside of the rachis of this new variety is usually smooth, whereas on the underside of the rachis of Manitou there are usually many stipitate glands. There may be from none to four small prickles in this location in either variety.

As the calyx breaks, the buds of this new variety are substantially longer in relation to their breadth than are the buds of Manitou. The bud color, as the calyx breaks, ranges from a deep golden yellow color with heavy reddishorange overcasts to deep reddish-orange, whereas on buds of Manitou in the same stage of development the color is a deep rosy-red.

This new variety is distinguished from its pollen parent, Summer Sunshine, in the following characteristics:

The plant of this new variety is taller and more vigorous,

and has a more erect habit of growth, than does the plant of Summer Sunshine.

The flowers of this new variety, usually held upright, are home on stronger and more erect stems than are the flowers of Summer Sunshine, and whereas Summer Sunshine may occasionally have two or more flowers to the stem, rather than only one, this new variety characteristically has only one flower to the stem and is less often found with more than one flower to the stem.

The peduncles of this new variety are more erect and are of larger caliper than are the peduncles of Summer Sunshine.

The unopen flower buds of this new variety are substantially wider at the base in relation to their length than are the buds of Summer Sunshine before they open. The opening flower buds of this new variety are longer than the opening flower buds of Summer Sunshine.

Whereas Summer Sunshine only occasionally has foli aceous appendages extending beyond the tip of the buds, these extending generally less thane one-half the bud length, the sepals of this new variety more frequently have such appendages, and these may often be as long in extent as the flower bud itself.

The flowers of this new variety are usually significantly larger than the flowers of Summer Sunshine; those of the former ranging in size from 4 /2 inches to 7 inches when fully opened and those of the latter being from 3 inches to 5 inches wide when fully opened. The flowers of this new variety characteristically have from 30 to 40 petals plus 10 to 16 petaloids, whereas the flowers of Summer Sunshine have between 22 and 28 petals plus 4 to 8 petaloids.

The flower color of this new variety may be described 'as being a pale, creamy yellow with light orangish-pink overtones, whereas the flower color of Summer Sunshine is a bright, deep yellow. The flower buds of this new variety, as the calyx breaks, are a deep golden yellow color heavily overlaid with a strong orangish-red, especially on the outer surface of the outside petals, whereas buds of Summer Sunshine are a bright yellow color.

The flowers of this new variety are considerably more fragrant than are the flowers of Summer Sunshine.

The flowers are usually borne singly on normal, medium stems. The plant blooms abundantly, both outdoors and in the greenhouse, and almost continuously during the growing season. The fragrance is moderate.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptivce. 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 average length to long, of average caliper, erect and stiff. Its color is near Strong Yellow Green, 5GY 6/8. It is entirely smooth, or may have from a few to numerous stipitate glands and a few small prickles. It may be observed that there are more prickles and stipitate glands on the peduncles of plants grown outdoors than on those which are grown in a greenhouse.

Before the calyx breaks, the bud is medium to large size, medium length, pointed, and with a conspicous neck.

As the calyx breaks, the color is near Strong Greenish Yellow, 10Y 8/11, overlaid with near Strong Red, 5R 4/12.

The inner surface of the sepals is lined with a fine, wooly tomentum. Margins of alternate sepals are lined with a fine, wooly tomentum, the margins of others usually having narrow foliaceous parts and small stipitate glands. The tips of the sepals sometimes have foliaceous appendages. The foliaceous parts generally are larger on plants which are grown outdoors. The outer surface of the sepals is usually smooth.

' As the first petal opens, it is average to large in size, being long, and ovoid to urn-shaped in form. The outer surface of the petal is between Strong Orange Yellow, 7.5YR 7/11, and Moderate Orange Yellow, 7.5YR 8/8, overlaid with near Strong Red, R 4/12. At the base, near the point of attachment, the petal is near Vivid Greenish Yellow, 7.5Y 8/12. The inner surface is near Vivid Yellow, 2.5Y 8/12, overlaid with near Strong Orange, 2.5YR 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 to large in size, being from 4 /2 inches to 7 inches across. The petalage is double, ranging from 30 to 40 petals, plus to 16 petaloids, which are arranged irregularly on flowers which are grown outdoors.

The form of the bloom is high centered at first, later becoming open and high centered. At first, the petals remain somewhat cupped, with tips reflexed outward; later, at maturity, they are more loosely cupped, with tips rolled outward. The petals are of medium texture, moderately leathery, with both the inside and outside satiny. The shape of all petals is obovate. The colors may be modified by being shaded and/ or washed with other colors.
