| Abstract: |
A new and distinct variety of shrub rose plant having a spreading ground cover growth habit is provided which forms attractive long-lasting half-double blossoms that are Rose Bengal suffused with Neyron Rose in coloration. The blossoms commonly are formed very abundantly and continuously and possess firm petals which detach cleanly. The vegetation is vigorous. The new variety is not particularly affected by cryptogamic diseases, and possesses good resistance to frost. Attractive ornamentation for growing in the landscape is provided by the new variety. |
| Claim: |
I claim:
1. A new and distinct variety of shrub rose plant characterized by the following combination of characteristics:
(a) forms attractive half-double blossoms which are Rose Bengal suffused with Neyron Rose,
(b) forms petals which are firm and drop off cleanly,
(c) forms medium green adult wood,
(d) exhibits a prostrate growth habit,
(e) exhibits excellent disease resistance, and
(f) is particularly well-suited for growing in the landscape as a ground cover;
substantially as herein shown and described. |
| 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 femaleparent (i.e., the seed parent) was the Meitiraca variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the Meimont variety (non-patented in the United States). The parentage of the new variety canbe summarized as follows:
The seeds resulting from the above pollination were sown and 11 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 is found that the new variety of shrub rose plant possesses the following combination of characteristics:
(a) forms attractive half-double blossoms which are Rose Bengal suffused with Neyron Rose,
(b) forms petals which are firm and drop off cleanly,
(c) forms medium green adult wood,
(d) exhibits a prostrate growth habit,
(e) exhibits excellent disease resistance, and
(f) is particularly well suited for growing in the landscape as a ground cover.
The new variety meets the needs of the horticultural industry for many uses. It can be grown to particular advantage as 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 to be strictly transmissible by asexual propagation that was carried out in France (e.g., by budding, grafting, cuttage, etc.) from one generation to another.
The new variety has been named the Meipelta 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 the plant parts of the new variety. The rose plants of the new variety describedherein were three years of age and were grown on their own roots in the open air at Le-Cannet-des-Maures, Var, France.

DETAILED DESCRIPTION
The chart used in the identification of the colors is that of the Royal Horticultural Society (R.H.S. Colour Chart). The terminology preceding the numbered reference has been added to indicate in common terms the corresponding color. Thedescription is based on three year old specimens of the new variety while grown outdoors on their own roots at Le-Cannet-des-Maures, Var, France.
