Abstract

A new and distinct cultivar of Rose plant named ‘Chewmaytime’, characterized by its upright, outwardly spreading and mounding plant habit; glossy dark green-colored leaflets; freely branching growth habit; freely flowering habit; large orange and yellow bi-colored single flowers; resistant to Black Spot and mildews; and good garden performance.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination ‘Chewmaytime’.
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 ‘Chewmaytime’.
The new Rose is a product of a planned breeding program conducted by the Inventor in Brockton, Shophire, United Kingdom. The objective of the breeding program was to develop new shrub Rose varieties with attractive flower coloration.
The new cultivar originated from a cross-pollination made by the Inventor in 1991 of an unnamed proprietary Rose seedling selection, not patented, as the female, or seed, parent with the Rose cultivar Laura Ford, not patented, as the male, or pollen, parent. The cultivar Chewmaytime was discovered and selected by the Inventor in 1992 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Newport, Shophire, United Kingdom.
Asexual reproduction of the new Rose by softwood cuttings at Newport, Shophire, United Kingdom since 1993, has shown that the unique features of this new Rose 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 ‘Chewmaytime’. These characteristics in combination distinguish ‘Chewmaytime’ as a new and distinct cultivar:
    • 1. Upright, outwardly spreading and mounding plant habit.
    • 2. Glossy dark green-colored leaflets.
    • 3. Freely branching growth habit.
    • 4. Freely flowering habit.
    • 6. Large orange and yellow bi-colored single flowers.
    • 7. Resistant to Black Spot and mildews.
    • 8. Good garden performance.
Plants of the new Rose differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Rose and the female parent selection differ in plant habit.
    • 2. Plants of the new Rose and the female parent selection differ in flower color as plants of the female parent selection have pale yellow-colored flowers.
Plants of the new Rose differ from plants of the male parent, the cultivar Laura Ford, in the following characteristics:
    • 1. Plants of the new Rose have larger leaves than plants of the cultivar Laura Ford.
    • 2. Plants of the new Rose and the cultivar Laura Ford differ in flower color as plants of the cultivar Laura Ford have pale yellow-colored flowers.
Plants of the new Rose can be compared to plants of the Rose cultivar Flower Carpet Yellow, disclosed in U.S. Plant Pat. No. 10,527. Plants of the new Rose differ from plants of the cultivar Flower Carpet Yellow in the following characteristics:
    • 1. Plants of the new Rose are more upright than plants of the cultivar Flower Carpet Yellow.
    • 2. Plants of the new Rose flower more continuously than plants of the cultivar Flower Carpet Yellow.
    • 3. Plants of the new Rose and the cultivar Flower Carpet Yellow differ in flower color as plants of the cultivar Flower Carpet Yellow have pale yellow-colored flowers.
Plants of the new Rose can be compared to plants of the Rose cultivar Bonanza, not patented. Plants of the new Rose differ from plants of the cultivar Bonanza in the following characteristics:
    • 1. Plants of the new Rose are more outwardly spreading than and not as upright as plants of the cultivar Bonanza.
    • 2. Plants of the new Rose have smaller leaves than plants of the cultivar Bonanza.
    • 3. Plants of the new Rose have shorter lateral branches than plants of the cultivar Bonanza.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Rose, 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 at the bottom of the sheet comprises a side perspective view of a typical flower of ‘Chewmaytime’ grown in an outdoor nursery.
The photograph at the top of the sheet is a close-up view of typical flowers of ‘Chewmaytime’.
 DETAILED BOTANICAL DESCRIPTION
The new Rose has 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.

Plants were about three years old when the photographs and description were taken. The photographs and description were taken during the late summer and early autumn.
