Hybrid tea rose plant named ‘JACwotte’

Abstract

A hybrid tea rose plant having large, high centered, blushed pink flowers; long cutting stems; dark green, glossy foliage; good disease resistance; and vigorous, upright growth.

Description

The 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 ‘JACyap’ (not patented), with an unnamed seedling (not patented).

The primary objective of this breeding was to produce a new rose variety having the high centered flower form and long cutting stems of the female parent, combined with the dark, glossy foliage, good disease resistance and vigorous, upright growth of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Soft cream, blushed pink flower color;

2. Large, high centered flowers;

3. Vigorous, upright growth;

4. Dark green, semi-glossy leaves;

5. Good disease resistance; and

6. Long cutting stems.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other 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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

Parentage:

Seed parent.—‘JACyap’ (unnamed seedling×unnamed seedling — not patented).

Pollen parent.—Unnamed seedling (JAColite — U.S. Plant Pat. No. 4,167×Silver Jubilee — not patented).

Form.—When first open, bloom is high centered. Permanence: Retains its form to the end; outer petals curl back with some quilling.

Petalage.—Number of petals under normal conditions: 35.

Color.—The upper sides of the petals are Yellow-Orange Group 17D on the bottom ¼ of the petal, and then Orange Group 27D on the rest of the petal surface, except for Red Group 49D on the petal edge. The reverse sides of the petals are Yellow-Orange Group 17D on the bottom ¼ of the petal, and then Orange Group 27D on the rest of the surface, except for Red Group 49D on the petal edge. The base of each petal has a small, ¼ inch×¼ inch Yellow-Orange Group 21B half moon at the point of attachment on both petal surfaces. The major color on the upper side is Orange Group 27D.

Variegations.—None.

Discoloration.—The general tonality at the end of the first day: No change. At the end of the third day: No change. There is no change until petal drop.

Fragrance.—Moderate; anise.

Petals:

Texture.—Thick.

Shape.—Round.

Form.—Tips slightly recurved; edges slightly quilled.

Arrangement.—Imbricated. There are no petaloids in the center.

Persistence.—Petals drop off cleanly before drying.
