Abstract

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

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘HORNIMROD’.
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 ‘Hornimrod’.
The new Rose plant is a product of a planned breeding program conducted by the Inventor in Stausted, Essex, 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 1998 of Rosa sempervirens ‘Meidomonac’, disclosed in U.S. Plant Pat. No. 5,105, as the female, or seed, parent with an unnamed proprietary seedling selection of Rosa hybrida, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor in 2004 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Stausted, Essex, United Kingdom.
Asexual reproduction of the new Rose plant by softwood cuttings at Stausted, Essex, United Kingdom since 2004, 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 ‘Hornimrod’. These characteristics in combination distinguish ‘Hornimrod’ as a new and distinct Rose plant:
    • 1. Upright and mounding plant habit.
    • 2. Glossy green-colored leaves.
    • 3. Freely branching growth habit.
    • 4. Freely flowering habit.
    • 5. Large hot 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, ‘Meidomonac’, in the following characteristics:
    • 1. Plants of the new Rose are more upright than plants of ‘Meidomonac’.
    • 2. Flowers of plants of the new Rose have fewer petals than flowers of plants of ‘Meidomonac’.
    • 3. Plants of the new Rose and ‘Meidomonac’ differ in flower color as plants of ‘Meidomonac’ have clear pink-colored flowers.
    • 4. Plants of the new Rose are more resistant to Black Spot than plants of ‘Meidomonac’.
Plants of the new Rose differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Rose are more freely flowering than plants of the male parent selection.
    • 2. Flowers of plants of the new Rose not as fragrant as flowers of plants of the male parent selection.
    • 3. Plants of the new Rose and the male parent selection differ in flower color as plants of the male parent selection have apricot-colored flowers.
    • 4. Plants of the new Rose are more resistant to Black Spot than plants of the male parent selection.
Plants of the new Rose can be compared to plants of the Rosa hybrida ‘Chewallbell’, disclosed in U.S. Plant Pat. No. 26,817. Plants of the new Rose differ from plants of ‘Chewallbell’ in the following characteristics:
    • 1. Plants of the new Rose are more upright than plants of ‘Chewallbell’.
    • 2. Flowers of plants of the new Rose are not as flat as flowers of plants of ‘Chewallbell’.
    • 3. Plants of the new Rose and ‘Chewallbell’ differ in flower color as plants of ‘Chewallbell’ have clear salmon 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 ‘Hornimrod’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Hornimrod’.
 DETAILED BOTANICAL DESCRIPTION
Plants of the new Rose have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

Plants were 1.5 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.
