Shrub rose plant named `JACpursh`

Abstract

Shrub rose plant with dark green, glossy foliage; vigorous, upright growth habit; fragrant flower with rapid petal drop; ability to root and grow from hardwood cuttings; resistance to disease; and production of bright orange hips.

Description

The present invention relates to a new and distinct variety of rose plant of the schrub class which was originated by me by crossing an unnamed seedling with the variety `JACsedi` (U.S. Plant Pat. No. 9,172).

The primary objective of this breeding was to produce a new rose variety having the excellent hardwood cutting rooting ability, the clean petal drop, and vigorous well-branched growth habit of the unnamed lavender shrub female parent combined with the very glossy foliage, purple flowers, and fragrance 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. Vigorous, upright well-branched growth habit;

2. Fragrant flowers;

3. Excellent ability to root from hardwood cuttings;

4. Glossy, disease resistant foliage;

5. Ability to drop petals cleanly;

6. Production of bright orange hips.

`JACpursh` also produces green fruit turning in August and September to orange. These fruit are substantially spherical (3/4" in diameter) and contain up to twenty seeds. Production of fruit does not prevent continued flowering. Fruit is persistant until late November in Somis, Calif., when it drops.

Asexual reproduction of this new variety by hardwood cuttings, 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.--Unnamed seedling.

Pollen parent.--`JACsedi` (U.S. Plant Pat. No. 9,172).

Classification:

Botanical.--Rosa hybrida.

Commercial.--Shrub.

FLOWER

Observations made from specimens grown in a garden environment at Somis, Calif. from January 1996-August 1997.

Form.--The bud form is long, pointed ovoid.

Color.--When sepals first divide, bud color is close to Red Group 53B with some streaks of Red Group 53C. When half blown, the upper sides of the petals are Red Group 53B with some white streaks and some fading toward petal edges to Red Group 53C; and the lower sides of the petals are Red Group 53B.

Sepals.--Color: Green group 138B with a distinct bronze color in the older sepals. Surface texture: Covered with fine hairs. There are three lightly appendaged sepals. There are two unappendaged sepals with hairy edges.

Receptacle.--Color: Green Group 137D. Shape: Funnel. Size: Small (1/4".times.3/16"). Surface: Smooth.

Peduncle.--Length: Short (21/2"-3"). Surface: Smooth. Color: Light green becoming increasingly bronzy as it ages. Strength: Stiff, erect.

Bloom:

Size.--Small. Average open size is 21/2-3 inches.

Petalage.--Number of petals under normal conditions: 15-20.

Color.--The upper sides of the petals are Red Group 53B with some white streaks and some fading on petal edges to Red Group 53C. The reverse sides of the petals are Red Group 53C. The base of each petal has a distinctive "white eye" which is a change in color from Red Group 53B to White Group 155D. There is also a small (1/8".times.1/8"), Yellow Group 4C half moon at the point of attachment. The major color on the upper side is Red Group 53B.

Variegations.--There are occasional white streaks on some petals.

Discoloration.--At the end of the first day: No change. At the end of the third day: No change. By day four or five, depending on temperature and sunlight intensity, there is a fading to Red Group 53C, then Red Group 53D. Petal drop is on day six or seven.

Petals:

Texture.--Thick.

Shape.--Deltoid.

Form.--Tips slightly recurved.

Arrangement.--Imbricated. Petaloids in the center are few.

Reproductive parts:

Anthers.--Size: Medium. Quantity: Many. Color: Yellow. Arrangement: Regular around styles.

Filaments.--Color: Yellow.

Pollen.--Color: Gold yellow.

Styles.--Color: Reddish-brown.

Stigmas.--Color: Greenish-white.

Plant:

Size.--Large (7 to 8".times.4 to 5").

Quantity.--Abundant.
