Abstract
A new and distinct Hybrid Tea Rose plant named ‘Schrawatt’, characterized by its glossy dark green leaves; freely branching habit; dark pink and white bi-colored flowers that are arranged in sprays; and good postproduction longevity.
Description
Botanical classification/cultivar designation: Rosa hybrida cultivar Schrawatt.
The present invention relates to a new and distinct cultivar of Hybrid Tea Rose plant, botanically known as Rosa hybrida, commercially produced as a cut flower, and hereinafter referred to by the name ‘Schrawatt’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program was to develop new spray-type cut Rose cultivars with attractive flower petal colors, long and strong stems, and good postproduction longevity.
The new cultivar originated from a cross-pollination made by the Inventor in 1998 of two unidentified proprietary selections, not patented. The cultivar Schrawatt was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in De Kwakel, The Netherlands.
Since 1999, asexual reproduction of the new cultivar by cuttings in De Kwakel, The Netherlands has shown that the unique features of the new cultivar are stable and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Schrawatt’. These characteristics in combination distinguish the new Hybrid Tea Rose as a new and distinct cultivar:
-
- 1. Glossy dark green leaves.
- 2. Freely branching habit.
- 3. Dark pink and white bi-colored flowers that are arranged in sprays.
- 4. Good postproduction longevity.
Plants of the Hybrid Tea Rose differ primarily from plants of the parent selections in flower color.
Plants of the Hybrid Tea Rose can be compared to plants of the cultivar Schovian, disclosed in U.S. Plant Pat. No. 9,629. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new cultivar differed from plants of the cultivar Schovian in the following characteristics:
-
- 1. Plants of the new Hybrid Tea Rose were more freely branching than plants of the cultivar Schovian.
- 2. Plants of the new Hybrid Tea Rose have smaller flowers than plants of the cultivar Schovian.
- 3. Plants of the new Hybrid Tea Rose have white and dark pink-colored flower petals whereas plants of the cultivar Schovian have white-colored flower petals.
Plants of the new Hybrid Tea Rose have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The accompanying colored photograph illustrates the new Hybrid Tea 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 Hybrid Tea Rose. The photograph comprises a top perspective view of a typical flowering stem of the new Hybrid Tea Rose.
The aforementioned photograph and following observations and measurements describe cut flowering stems of plants grown in De Kwakel, The Netherlands, in a glass-covered greenhouse with day and night temperatures about 19 and 15° C., respectively. Flowering stems used in the photograph and the description were about five months old and had been pruned. 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.
