Abstract

A new and distinct cultivar of Rose plant named ‘ESM R896’, characterized by its upright and relatively strong flowering stems; relatively moderately vigorous growth habit; dark green-colored leaves; orange-colored flower petals and petaloids that become darker orange with development giving the flower a bi-colored appearance; petals and petaloids are relatively resistant to bruising; and excellent postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘ESM R896’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Genviv Holdings, LLC of Miami, Florida on Apr. 18, 2025, application No. 2025/0850. Foreign priority is not claimed to this European Community Plant Breeder's Rights application.

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 a cut flower Rose plant, and hereinafter referred to by the name ‘ESM R896’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program was to develop new cut flower Rose varieties with unique flower colors and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor in March 2020 of a proprietary Rose selection identified as line 974, not patented, as the female, or seed, parent with a proprietary Rose selection identified as line 1019, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in El Quinche, Pichincha, Ecuador in August 2021.

Asexual reproduction of the new Rose plant by bud grafting in El Quinche, Pichincha, Ecuador since January 2022 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

Plants of the new Rose have not been observed under all possible combinations of 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.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ESM R896’. These characteristics in combination distinguish ‘ESM R896’ as a new and distinct Rose plant:

• • 1. Upright and relatively strong flowering stems.
  • 2. Relatively moderately vigorous growth habit.
  • 3. Dark green-colored leaves.
  • 4. Orange-colored flower petals and petaloids that become darker orange with development giving the flower a bi-colored appearance.
  • 5. Petals and petaloids are relatively resistant to bruising.
  • 6. Excellent postproduction longevity.

Plants of the new Rose differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Rose are not as productive as plants of the female parent selection.
  • 2. Flower buds of plants of the new Rose are shorter than flower buds of plants of the female parent selection.
  • 3. Flowers of plants of the new Rose have fewer petals than flowers of plants of the female parent selection.

Plants of the new Rose differ from plants of the male parent selection in the following characteristics:

• • 1. Flower buds of plants of the new Rose are shorter than flower buds of plants of the male parent selection.
  • 2. Flowers of plants of the new Rose have fewer petals than flowers of plants of the male parent selection.
  • 3. Flowers of plants of the new Rose are orange in color whereas flowers of plants of the male parent selection are brown in color.

Plants of the new Rose can also be compared to plants of Rosa hybrida ‘Silantoi’, not patented. In side-by-side comparisons, plants of the new Rose differ from plants of ‘Silantoi’ in the following characteristics:

• • 1. Developed stems of plants of the new Rose are darker brownish green in color than developed stems of plants of ‘Silantoi’.
  • 2. Plants of the new Rose have smaller flowers than plants of ‘Silantoi’.
  • 3. Flowers of plants of the new Rose are darker orange in color than flowers of plants of ‘Silantoi’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographic sheet and the following observations and measurements describe plants grown in ground beds in a polyethylene-covered greenhouse in Cayambe, Pichincha, Ecuador and under typical cut Rose production practices. Plants were grown year round and were 17 months old when the photographs and the description were taken. During the production of the plants, day temperatures ranged from 17° C. to 21° C., night temperatures ranged from 5° C. to 8° C. and light levels averaged 19,338 lux.
