USPP11025P - Miniature rose plant named `Meiptima` - Google Patents

Abstract

A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms attractive double lavender blossoms on a substantially continuous basis. The blossoms tend to be borne above the foliage where they are clearly visible. A dense, narrow and bushy growth habit is exhibited that renders the plant well suited for growing as attractive ornamentation in the landscape. The buds are conical in configuration and are elegantly shaped. The foliage is dark green and contrasts nicely with the lavender blossoms.

Description

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant 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 product of the pollination of the `Keimove` variety (non-patented in the United States) and the `Ruiblun` variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the `Lavender Jewel` variety (U.S. Plant Pat. No. 4,480). The parentage of the new variety can be summarized as follows:

(`Keimove`×`Ruiblun`)×`Lavender Jewel`.

The seeds resulting from the above pollination were sown and small plants 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 Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms conical elegantly-shaped lavender buds,

(b) forms in abundance on a substantially continuous basis attractive double lavender blossoms that tend to be borne above the foliage,

(c) exhibits a dense, narrow and bushy growth habit, and

(d) forms attractive semi-glossy dark green foliage.

The blossoms are commonly positioned above the foliage where they are unobstructed to view, and contrast nicely with the dark green foliage.

The new variety well meets the needs of the horticultural industry. It is particularly well-suited for use as attractive ornamentation in the landscape.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned methods as performed in France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named the `Meiptima` 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 were nine months of age and were observed during March while growing on their own roots outdoors at LeCannet des Maures, Var, France.
