Rose plant

Abstract

A hybrid tea rose variety having bright red flowers opening from dark red buds, borne on an upright, heavily branched plant.

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 Ernest H. Morse with Red Planet.

The primary objective of this breeding was to produce a vigorous, tall cultivar bearing large bright red blooms. 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. An unusually upright habit, a vigorous plant, branching readily from the base.

2. Tight unopened buds of a deep red.

3. Opened buds to fully opened blooms a bright red, Wilson's Blood Red.

4. Strong heavy canes with less than average number of prickles.

5. Slight fragrance.

6. A better than average resistance to rose powdery mildew.

7. Large open flowers, often 6 or 7 inches in diameter.

Asexual reproduction of this new cultivar 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 show 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.--Darker streaks on outside petals between dividing sepals.

Discoloration.--General tonality at end of first day, no change; at end of third day, no change.

Fragrance.--Slight.

Petals:

Texture.--Thick.

Shape.--Round, base of petals at point of attachment slightly elongated.

Form.--Tips slightly recurved; edges slightly quilled.

Arrangement.--Loosely imbricated. Petaloids in center few.

Lastingness.--On the plant: Long; as cut flower: Long.

Reproductive parts:

Stamens, anthers.--Medium; color: yellow; Arrangement: regular around styles.

Filaments.--Color: Pink.

Pollen.--Gold Yellow.

Styles.--Color: Pink.

Claims

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, unusually upright but heavily branched plant; dark red flower bud; bright red open flower of 20 to 25 petals; slight fragrance; strong heavy canes with few thorns and better than average resistance to rose powdery mildew.
