ROSE PLANT Filed Jan. 9, 1962 INVENTOR. GORDON J. VON ABRAMS AT ORNEY United States Patent 2,245 ROSE PLANT Gordon J. Von Abrams, 3463 NW. Savier St,

Portland, Oreg. Filed .l'an. 9, 1962, Ser. No. 165,266 1 Claim. (Cl. 47-61) This invention comprises a new and distinct variety of rose plant of the commercial hybrid tea class. In the pollination which took place in the breeding of this new variety the seed parent had been produced by crossing the rose variety Charlotte Armstrong (Plant Patent No. 455) with the rose variety Mme. Henri Guillot (Plant Patent No. 337) and the pollen parentby crossing the rose variety Multnomah (Plant Patent No. 883) with the rose variety Charles Mallerin (Plant Patent No. 933).

The main objective of this particular breeding was to develop a new variety of rose which would produce flowers having a strong fragrance and a distinct soft reversebicolor flower color. This objective was achieved.

The pollination took place at Scappoose, Oregon, in the spring of 1953 and was performed by me. Subsequent asexual propagation at the same location was performed by bud-grafting. This new variety of rose has been shown to retain its initial distinguishing characteristics through repeated vegetative reproductions by budgrafting.

This new variety of rose is not similar to any other variety of rose in commerce known to me. The closest comparison would, I believe, be with the rose variety Angel Wings (Plant Patent No. 1,865); but the open flowers of the latter are more yellow in color, less fragrant, with fewer petals, the flower buds are lighter colored, more pointed and longer, the plant is taller, and thefoliage is less glaucous, than is the case with this new variety of rose.

The new variety originated as a seedling, and is a medium tall bush type. It is particularly suitable for use outdoors, for garden decoration and for cut-flowers. The flowers have an intense pleasing fragrance, and have a distinct color combination and flower form, as described in detail hereinafter. The light color and grayish appearance of the foliage of the plant adds further to its distinctiveness.

The accompanying illustration was made from specimens grown outside at Scappoose, Oregon, during July 1960, the colors shown being as nearly true as is reasonably possible in a color reproduction of this type.

In the more detailed description which follows, these 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, D.C., 1912 (abbreviated R).
