Abstract

A new and distinct cultivar of Rose plant named ‘Scrivjean’, characterized by its upright, low spreading and mounding plant habit; dense and glossy foliage; freely branching growth habit; freely flowering habit; large light pink, yellow and white-colored flowers; resistance to Black Spot; and good garden performance.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘SCRIVJEAN’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as an ornamental shrub, and hereinafter referred to by the name ‘Scrivjean’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Kidderminster, Worcester, United Kingdom. The objective of the breeding program was to develop new uniform Rose varieties with attractive flower coloration and better disease resistance.

The new Rose plant originated from a cross-pollination made by the Inventor in 1994 of Rosa hybrida ‘Flower Carpet’, disclosed in U.S. Plant Pat. No. 7,282, as the female, or seed, parent with Rosa hybrida ‘Shine On’, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor in 1995 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Kidderminster, Worcester, United Kingdom.

Asexual reproduction of the new Rose plant by softwood cuttings at Kidderminster, Worcester, United Kingdom since 1997, has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Scrivjean’. These characteristics in combination distinguish ‘Scrivjean’ as a new and distinct cultivar of Rose:

- 1. Upright, low spreading and mounding plant habit.
- 2. Dense and glossy foliage.
- 3. Freely branching growth habit.
- 4. Freely flowering habit.
- 5. Large light pink, yellow and white-colored flowers.
- 6. Resistant to Black Spot.
- 7. Good garden performance.

Plants of the new Rose differ from plants of the female parent, ‘Flower Carpet’, in the following characteristics:

- 1. Plants of the new Rose are more compact than plants of ‘Flower Carpet’.
- 2. Plants of the new Rose have darker green-colored leaves than ‘Flower Carpet’.
- 3. Plants of the new Rose and ‘Flower Carpet’ differ in flower color as plants of ‘Flower Carpet’ have deep pink-colored flowers.

Plants of the new Rose differ from plants of the male parent, ‘Shine On’, in the following characteristics:

- 1. Plants of the new Rose are more prostrate than and not as upright as plants of ‘Shine On’.
- 2. Plants of the new Rose and ‘Shine On’ differ in flower color as plants of ‘Shine On’ have orange and pink-colored flowers.
- 3. Plants of the new Rose are more resistant to Black Spot than plants of ‘Shine On’.

Plants of the new Rose can be compared to plants of the Rosa hybrida ‘Horcoherent’, disclosed in U.S. Plant Pat. No. 15,982. Plants of the new Rose differ from plants of ‘Horcoherent’ in the following characteristics:

- 1. Plants of the new Rose are more freely flowering than plants of ‘Horcoherent’.
- 2. Plants of the new Rose and ‘Horcoherent’ differ in flower color as plants of ‘Horcoherent’ have orange, pink and yellow-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose.

The photograph on the first sheet comprises a top perspective view of a typical plant of ‘Scrivjean’.

The photograph on the second sheet is a close-up view of typical flowers, flower buds and leaves of ‘Scrivjean’.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown in Grand Haven, Mich., in an outdoor nursery and under commercial production practices during the spring and summer. Plants were three years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
