Abstract

A novel rose plant of the hybrid tea class, having vigorous and heavily branched stems, abundance and continuity of blooms with distinct color shadings.

Description

The present invention relates to a new and distinct cultivar of rose plant of the hybrid tea class which was originated by me by crossing the cultivar [(Chic Parisien × Super Star) × (Gloire de Rome × Impeccable)] with pollen from the cultivar (Super Star × Samourai).

The primary objective of this breeding was to produce a cultivar of the hybrid tea class, particularly suitable for garden use, having an upright, vigorous plant, and producing flowers of a novel character, especially in color. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in this new cultivar and which distinguish it from its parents as well as from all other cultivars of which I am aware:

1. A very vigorous, heavily branched, upright-growing plant of the hybrid tea class.

2. An abundance and continuity of flowers opening as Signal Red, changing slightly to Blood Red.

3. The veins of the flower petals generally are darker than interveinal areas, but as the flower opens, the distal portion of each petal darkens to near black in the interveinal areas, giving a distinctive shaded appearance to the petals.

Asexual reproduction of this new cultivar by budding as performed at Evry, France, and at Irvine, 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 cultivar 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 Wilson's Horticultural Color Chart, except where ordinary dictionary significance of color is indicated.

Variegations.--Veins are much darker, nearly black. Petal tips darken in irregular areas to nearly black.

Discoloration.--General tonality at end of first day, none; third day, darkened areas increase in size to approximately 1/3 of petal area.

Fragrance.--Very little.

Petals:

Texture.--Thick, leathery.

Shape.--Round.

Form.--Flat.

Arrangement.--Imbricated. Petaloids in center, many.

Persistence.--Drop off cleanly.

Lastingness.--On the plant, long. As cut flower, long.

Reproductive parts:

Stamens, anthers.--Large. Color, yellow. Arrangement, regular around styles.

Filaments.--Color: Crimson (22/1).

Pollen.--Gold yellow.

Styles.--Color: White, mottled with crimson streaks, sometimes all crimson.

Claims (1)

I claim:

1. A new and distinct cultivar of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its vigorous upright plant, and its flower color of Signal Red to Blood Red with distinct darker veins and darker, almost black, shadings.
