Abstract

A new and distinct cultivar of Rose plant named ‘Florirosavio04’, characterized by its upright flowering stems; vigorous growth habit; freely branching plant habit; and strongly fragrant flowers that are light violet in color.

Description

Botanical designation: Rosa hybrida.
Cultivar denomination: ‘FLORIFOSAVIO04’.
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 ‘Florirosavio04’.
The new Rose plant is a product of a planned breeding program conducted by the Inventors in Katori-shi, Chiba-ken, Japan. The objective of the breeding program was to develop new vigorous and fragrant cut flower Rose varieties with novel and attractive flower colors and excellent postproduction longevity.
The new Rose plant is a naturally-occurring whole plant mutation of Rosa hybrida ‘KEIhaburu’, disclosed in U.S. Plant Pat. No. 19,509. The new Rose plant was discovered and selected by the Inventors as a single plant within a population of plants of ‘KEIhaburu’ in a controlled greenhouse environment in Katori-shi, Chiba-ken, Japan.
Asexual reproduction of the new Rose plant by cuttings in a controlled environment in Katori-shi, Chiba-ken, Japan 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 environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Florirosavio04’. These characteristics in combination distinguish ‘Florirosavio04’ as a new and distinct Rose plant:
    • 1. Upright flowering stems.
    • 2. Vigorous growth habit.
    • 3. Freely branching plant habit.
    • 4. Strongly fragrant flowers that are light violet in color.
Plants of the new Rose differ from plants of the parent, ‘KEIhaburu’ primarily in flower color as plants of ‘KEIhaburu’ have violet blue-colored flowers.
Plants of the new Rose can be compared to plants of Rose ‘Lavande’, not patented. In side-by-side comparisons conducted in Katori-shi, Chiba-ken, Japan, plants of the new Rose had larger flowers than plants of ‘Lavande’.
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 at the top of the sheet comprises a side perspective view of typical flowering plants of ‘Florirosavio04’ grown in ground beds.
The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Florirosavio04’.
 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 ground beds in a glass-covered greenhouse in Katori-shi, Chiba-ken, Japan and under typical commercial Rose production practices. Plants were one year old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
