Abstract

A new and distinct variety of rose plant, referred to by its cultivar name, ‘MEIJOVAUX’, is disclosed. The new variety forms attractive, semi-double creamy pink with a creamy yellow center colored flowers. Attractive rather dense with a semi-glossy aspect foliage is formed, which contrasts beautifully with the blossoms. A ground cover growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘MEIJOVAUX’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2021/1085, which was filed at Community Plant Variety Office in the European Union on Apr. 21, 2021, the contents of which are hereby incorporated by reference for all purposes.

BACKGROUND OF THE INVENTION

The new variety of Rosa hybrida plant of the present invention was discovered as a spontaneous mutation in a single cutting of the variety ‘MEIJOCOS’ (U.S. Plant Pat. No. 18,874) in December 2015 in Park City, Fla., United States of America as a spontaneous mutation from a single cutting. The new variety was selected and preserved primarily because of its color difference from the ‘MEIJOCOS’ parent variety.

The parentage of the new variety can be summarized as follows:
spontaneous mutation in a single cutting of ‘MEIJOCOS’

The new variety has been found to undergo asexual propagation in West Grove, Pa. by a number of routes, including softwood cuttings. Asexual propagation by the above-mentioned techniques in West Grove, Pennsylvania has shown that the characteristics of the new variety are stable and are strictly transmissible by softwood cuttings asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

- (a) provides a ground cover growth habit with procumbent vegetation,
- (b) forms semi-double creamy pink with a creamy yellow center colored flowers, and
- (c) exhibits a semi-glossy foliage.

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 of the present invention can readily be distinguished from its ancestors. More specifically, the ‘MEIJOCOS’ variety (i.e., the parent variety) displays deep pink with a white center colored flowers, whereas the new variety displays creamy pink with a creamy yellow center colored flowers. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIGALPIO’ variety (U.S. Plant Pat. No. 17,877) displays smaller sized flowers compared to the flowers of new variety.

The new variety has been named ‘MEIJOVAUX’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph of the drawing shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately one year of age and were observed during September while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the drawing.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2001 edition), 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 September while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France.
