Hybrid Tea Rose Plant Named ‘ESM R895’

Botanical designation: Rosa hybrida. Cultivar denomination: ‘ESM R895’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida , commercially produced and used as a cut flower Rose plant, and hereinafter referred to by the name ‘ESM R895’. 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 December 2019 of a proprietary Rose selection identified as line R1104, not patented, as the female, or seed, parent with a proprietary Rose selection identified as line R974, 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 February 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 R895’. These characteristics in combination distinguish ‘ESM R895’ as a new and distinct Rose plant: 1. Upright and moderately strong flowering stems. 2. Moderately vigorous growth habit. 3. Glossy dark green-colored leaves. 4. Deep pink-colored flower petals and petaloids that become lighter pink in color with development. 5. Excellent postproduction longevity. Plants of the new Rose differ from plants of the female parent selection in the following characteristics: 1. Flower buds of plants of the new Rose are not as tall as flower buds of plants of the female parent selection. 2. Flower petals of plants of the new Rose are deep pink becoming lighter pink in color whereas flower petals of plants of the female parent selection are red in color. 3. Flower petals of plants of the new Rose are not as thick as flower petals of plants of the female parent selection. 4. Flowers of plants of the new Rose do not open as fully as 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. Plants of the new Rose are produce fewer flowering stems per plant per year than plants of the male parent selection. 2. Flower petals of plants of the new Rose are deep pink becoming lighter pink in color whereas flower petals of flowers of plants of the male parent selection are yellow in color. 3. Flowers of plants of the new Rose do not have a detectable fragrance whereas flowers of plants of the male parent selection have a detectable fragrance. 4. Flowers of plants of the new Rose do not open as fully as flowers of plants of the male parent selection. Plants of the new Rose can also be compared to plants of Rosa hybrida ‘RUICL1805A’, not patented. In side-by-side comparisons, plants of the new Rose differ from plants of ‘RUICL1805A’ in the following characteristics: 1. Developed stems of plants of the new Rose are dark brownish green in color whereas developed stems of plants of ‘RUICL1805A’ are dark green in color. 2. Flower buds of plants of the new Rose are narrower than flower buds of plants of ‘RUICL1805A’. 3. Flowers of plants of the new Rose have fewer petals than flowers of plants of ‘RUICL1805A’. BRIEF DESCRIPTION OF THE PHOTOGRAPH The accompanying colored photographic sheet illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant. On the left side of the photographic sheet is a side perspective view of a typical flowering stem of ‘ESM R895’. At the upper right of the photographic sheet is a close-up view of a typical developed flower of ‘ESM R895’. And at the lower right of the photographic sheet are close-up views of the upper and lower surfaces of typical leaves of ‘ESM R895’. 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 produced under typical cut Rose production practices. Plants were grown year round and were 47 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.
