CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to Plant Breeders' Right Application Number 2018/2421, which was filed in the European Union on Sep. 24, 2018, and to Plant Breeders' Right Application Number 32561, which was filed in Japan on Nov. 1, 2017, the contents of which are hereby expressly incorporated by reference in their entirety for all purposes.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida miniature rose plant of the present invention was discovered during Spring 2015 at Honjo City, Saitamam pref. Japan. The new variety is a spontaneous mutation of the ‘AYA NO5’ variety and was selected and preserved primarily because of its color difference from the ‘AYA NO5’ parent variety.
The parentage can be summarized as follows:
- spontaneous mutation of ‘AYA NO5’.
It was found that the new miniature rose plant of the present invention possesses the following combination of characteristics:
- (a) displays a multitude of small, dark deep pink flowers,
- (b) forms attractive ornamental dark green foliage,
- (c) forms vigorous vegetation, and
- (d) exhibits good tolerance to Black Spot and Rust.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.
The new variety can be readily distinguished from its ancestors. More specifically, the ‘AYA NO5’ variety (i.e., the parent) exhibits light pink colored flowers, whereas the new variety displays dark deep pink colored flowers.
The new variety has been found to undergo asexual propagation in France by a number of routes including budding, grafting, and cutting. Asexual propagation in France by these routes has shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
The new variety has been named ‘HOHOEMI ROUGE’.

DETAILED BOTANICAL DESCRIPTION
The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of one-year-old specimens of the new variety during July while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France.
