INVENTOR. GORDON J. VON ABRAMS BY v ATTORNEY Plant Pat. 2,162 Patented Aug. 14, 1962 2,162 ROSE LANT Gordon J. Von Abrams, Portland, reg., assignor t0 Eldon Pinkeney Dering, Scappoose, Oreg. Filed Aug. 3, 1961, Ser. No. 129,193 1 Claim. (Cl. 47-61) This invention comprises a new and distinct variety of rose plant of the commercial hybrid tea class which was obtained by crossing two hybrid rose plants (not in commerce) each of which had been obtained by crossing the rose variety Multnomah (Plant Patent No. 883) and the rose variety Peace (Plant Patent No. 591).

The objectives in the breeding of this new rose variety were, in part, the obtaining of a rose variety of exceptional vigor bearing large flowers the petals of whichare red on one side and bright yellow on the other side, and also having bright glossy foliage. These objectives were achieved.

The principal distinguishing features of this new rose variety are the following: the plant is very tall and well formed, having heavy, but not awkward, branches; the flowers are large and the flower petals are yellow on the outside and red on the inside. Also the flowers are further characterized by a tendency to quarter during periods of rapid growth. The plant is semi-hardy and provides a tall, upright bush very suitable for outdoors both for garden decoration and for out flowers.

The crossing of the varieties for producing this new variety took place at Scappoose, Oregon, in the spring of 1952. The first flower was produced from this new plant in the spring of 1954. Subsequent propagation of the plant has been by successive asexual reproductions through budgrafting at Scappoose, Oregon. The plant has retained its distinguishing characteristics throughout such propagation.

This new variety is somewhat similar, particularly in flower coloration, to the rose variety Love Song (Plant Patent No. 1,360). However, the plant of the new variety is taller and more vigorous than Love Song, the foliage is slightly less glossy and the young growth is more red than Love Song; it has fewer petals, has more red on the outside of the bud, has a paler yellow on the outside of the mature petal, and bears more of its blooms on long single stems than Love Song. Also the peduncle of the new variety is straight, whereas that of Love Song tends to be crooked.

The accompanying illustration shows the rose plant in color with separated blooms in different stages of development.

A description in detail of the new variety follows and in the description the following color references are used: (1) Wilson, R. F.Royal Horticultural Society Colour Chart, England 1940 (abbreviated W.).

(2) Ridgway, R.-Color Standards and Color Nomenclature, Washington, DC, 1912 (abbreviated R.).

Flowers The flowers are usually three to five per stem, on long strong stems; but sometimes are borne singly. The plant produces a moderate quantity of blooms outdoors and blooms continuously throughout the season. The flower longevity is greater than average.

2 Petals:

Substance.Medium thick, soft, flexible.

Texture.0utside shiny; inside satiny.

Shape and size (in open flower) .Outside petallarge, obovate (i.e.4.5 x 6.5 cm.); apex entire or irregular. Intermediate petal-obovate (i.e.4 x 6 cm.); apex entire or irregular. Inside petals usually contorted.

The following description of a newly-opened flower was made in August 1960 from specimens grown outdoors near Scappoose, Oregon.

Colon-Outside petal: Outer surface spot of Aureolin (W. 3, .p. 3) at basal tip. Base near Canary Yellow (W. 2/2, p. 2) fading gradually upward to near Canary Yellow (W. 2/ 3, p. 2) blending in the apical third to near Crimson (W. 22/2 to 22/ 3, p. 22). Inner surface-base near Canary Yellow (W. 2 to 2/2, p. 2) merging sharply with near Crimson (W. 22/1 to 22/2, p. 22) at a point ca. /5 to A the distance from base to apex. Inside petal: Outer surfacebase near Aureolin (W. 3, p. 3), fading gradually upward to near Saffron Yellow (W. 7/3, p. 7) often slightly flushed or marked with near Geranium Lake (W. 20/2, p. 20) near apex or along apical-lateral margins. Inner surfacebase near Aureolin (W. 3, p. 3), changing abruptly to near Cherry (W. 722, p. 157) at a point about /5 or less the distance from base to apex.

General color efiecL-Near Crimson (W. 22 to 22/ 1,

The following description of a mature flower was made in August 1960, from specimens which had been open for a period of three days on a plant grown outdoors, near Scappoose, Oregon.

Colors. Outside petal: Outer surfacebase near Aureolin (W. 3/ 1, p. 3) fading gradually upward to Aureolin (W. 3/ 3, p. 3) or nearer white.

At a point approximately A5 or less than /6 the distance from base to apex, the yellow area merges abruptly with near Tyrian Rose (W. 24 to 24/ 1, p. 24).
