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 the variety, South Seas, U.S. Plant Pat. No. 2,184, with pollen of the variety, Tonight, U.S. Plant Pat. No. 3,522.

The primary objective of this breeding was to produce a new rose variety of the hybrid tea class similar to the parent, South Seas, but with more intense color. 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. An upright plant similar in habit to the seed parent, South Seas.

2. A uniform flower color very close to The RHS Colour Chart #34A.

3. Large, brown prickles, angled slightly downward.

4. A very slight fragrance.

5. Leaves of five or seven leaflets.

Asexual reproduction of this new variety by budding as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions are established and are 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.
