Abstract

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

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Hormeteoric’.

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 ‘Hormeteoric’.

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 shrub Rose varieties with attractive flower coloration.

The new Rose plant originated from a cross-pollination made by the Inventor in 1994 of Rosa hybrida ‘Anna Ford’, not patented, as the female, or seed, parent with Rosa hybrida ‘Euphorbia’, 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 outdoor nursery environment in Stausted, Essex, United Kingdom.

Asexual reproduction of the new Rose plant by softwood cuttings at Stausted, Essex, United Kingdom since 1995, 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 ‘Hormeteoric’. These characteristics in combination distinguish ‘Hormeteoric’ as a new and distinct cultivar of Rose:

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

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

- 1. Plants of the new Rose are more outwardly spreading than plants of ‘Anna Ford’.
- 2. Plants of the new Rose and ‘Anna Ford’ differ in flower color as plants of ‘Anna Ford’ have vermillion-colored flowers.

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

- 1. Plants of the new Rose have darker green-colored leaves than plants of ‘Euphorbia’.
- 2. Plants of the new Rose and ‘Euphorbia’ differ in flower color as plants of ‘Euphorbia’ have orange and yellow-colored flowers.
- 3. Plants of the new Rose are more resistant to Black Spot than plants of ‘Euphorbia’.

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 have darker green-colored leaves than plants of ‘Horcoherent’.
- 2. Flowers of plants of the new Rose have more petals than flowers of plants of ‘Horcoherent’.
- 3. 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 at the bottom of the sheet (FIG. 2) comprises a side perspective view of a typical plant of ‘Hormeteoric’ ground in an outdoor nursery.

The photograph at the top of the sheet (FIG. 1) is a close-up view of typical flowers of ‘Hormeteoric’.

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.
