Abstract

A hybrid tea rose variety having near red to shell pink blooms on medium, strong stems, blooms having extemely stiff petals and very little fragrance.

Description

This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing two unnamed varieties.

The primary objective of this breeding was to produce a new rose variety of the hybrid tea class, producing numerous blooms of a distinctive pink color and strong, substantive petals. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:

1. A vigorous, upright plant of the hybrid tea class.

2. Reddish purple new foliage and large dark green mature foliage.

3. Buds and open flowers of color commonly called shell pink, equal to Royal Horticultural Society's Red Group 38C.

4. Extremely stiff petals.

5. Little fragrance.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color in terminology in accordance with the Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.

Claims (1)

I claim:

1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a vigorous upright plant, reddish new foliage, shell pink flowers with very stiff petals, and little fragrance.
