Abstract

A new and distinct cultivar of Rose plant named ‘Chewallbell’, characterized by its upright and mounding plant habit; glossy green-colored leaves; freely branching growth habit; freely flowering habit; large clear salmon pink-colored flowers; resistance to Black Spot; and good garden performance.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘CHEWALLBELL’.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct Rose plant, botanically known as Rosa hybrida, commercially used as an ornamental Shrub Rose and hereinafter referred to by the name ‘Chewallbell’.
The new Rose plant is a product of a planned breeding program conducted by the Inventor in Newport, Shropshire, United Kingdom. The objective of the breeding program was to develop new uniform and disease-resistant shrub Rose plants with large and attractive flowers.
The new Rose plant originated from a cross-pollination made by the Inventor in June, 1999 of Rosa hybrida ‘Anna Livia’, not patented, as the female, or seed, parent with Rosa hybrida ‘Scrivbell’, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor in 2005 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Newport, Shropshire, United Kingdom.
Asexual reproduction of the new Rose plant by softwood cuttings at Newport, Shropshire, United Kingdom since 2005 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 ‘Chewallbell’. These characteristics in combination distinguish ‘Chewallbell’ as a new and distinct Rose plant:
    • 1. Upright, somewhat outwardly spreading and mounding plant habit.
    • 2. Glossy green-colored leaves.
    • 3. Freely branching growth habit.
    • 4. Freely flowering habit.
    • 5. Large clear salmon pink-colored flowers.
    • 6. Resistant to Black Spot (Diplocarpon rosae).
    • 7. Good garden performance.
Plants of the new Rose differ from plants of the female parent, ‘Anna Livia’, in the following characteristics:
    • 1. Plants of the new Rose are denser and bushier than and not as open as plants of ‘Anna Livia’.
    • 2. Flowers of plants of the new Rose are flatter than flowers of plants of ‘Anna Livia’.
    • 3. Flowers of plants of the new Rose are not as fragrant as flowers of plants of ‘Anna Livia’.
    • 4. Plants of the new Rose and ‘Anna Livia’ differ in flower color as plants of ‘Anna Livia’ have orange pink-colored flowers.
Plants of the new Rose differ from plants of the male parent, ‘Scrivbell’, in the following characteristics:
    • 1. Plants of the new Rose are denser and bushier than and not as open as plants of ‘Scrivbell’.
    • 2. Flowers of plants of the new Rose are flatter than flowers of plants of ‘Scrivbell’.
    • 3. Flowers of plants of the new Rose are not as fragrant as flowers of plants of ‘Scrivbell’.
    • 4. Plants of the new Rose and ‘Scrivbell’ differ in flower color as plants of ‘Scrivbell’ have pink and white-colored flowers.
Plants of the new Rose can be compared to plants of the Rosa hybrida ‘Hornimrod’, disclosed in U.S. Plant patent application Ser. No. 13/998,234. Plants of the new Rose differ from plants of ‘Hornimrod’ in the following characteristics:
    • 1. Plants of the new Rose are not as upright as plants of ‘Hornimrod’.
    • 2. Flowers of plants of the new Rose are flatter than flowers of plants of ‘Hornimrod’.
    • 3. Plants of the new Rose and ‘Hornimrod’ differ in flower color as plants of ‘Hornimrod’ have hot pink-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 plant.
The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Chewallbell’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flower bud and open flower of ‘Chewallbell’.
 DETAILED BOTANICAL DESCRIPTION
