USPP6281P - Rose plant--Meibalbika variety - Google Patents

Abstract

A new and distinct variety of shrub rose plant is provided which forms attractive semi-double blossoms having excellent color persistence which are carmine pink suffused with a scarlet blush on the edges. Plants of the new variety are particularly floriferous in the springtime and form attractive orange fruit in the autumn. Exceptionally good disease resistance also is exhibited. The new variety is well adapted for growing in the landscape.

Description

SUMMARY OF THE INVENTION

The new variety of shrub rose plant of the present invention was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the Meigurami variety. The male parent (i.e., the pollen parent) of the new variety was a plant formed by crossing the Curiousa variety by the City of Leeds variety. The parents of the new variety are non-patented in the United States. The parentage of the new variety can be summarized as follows:

Meigurami×(Curiosa×City of Leeds).

The seeds resulting from the above pollination were sown and 86 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

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

(a) forms attractive semi-double blossoms having an excellent color persistence which are carmine pink suffused with a scarlet blush on the edges,

(b) is particularly floriferous in the springtime,

(c) forms attractive orange fruits in the fall,

(d) is exceptionally disease resistant,

(e) exhibits a propensity to readily undergo asexual propagation from cuttings, and

(f) is particularly well suited for growing in the landscape.

The new variety meets the needs of the horticultural industry for all uses. It can be grown to advantage as an attractive ornamentation in parks, gardens, public areas, and residential landscapes.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation from one generation to another.

The new variety has been named the Meibalbika variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, typical specimens of plant parts of the new variety. The rose plants of the one variety described herein were approximately three years of age and were grown outdoors during September on Rose froebelii understock at Cannet des Maures, Var, France.
