Abstract: A new and distinct variety of rose plant of the miniature class is provided which abundantly forms attractive small double pink blossoms. A hanging growth habit is exhibited that renders the plant well suited for growing outdoors in a hanging basket. The plant propagates well from cuttings. The blossoms possess a slight fragrance, and the medium green foliage is semi-glossy.
Claim: I claim:

1. A new and distinct variety of miniature rose plant characterized by the following combination of characteristics:

(a) forms in abundance attractive small double pink blossoms,

(b) exhibits a hanging growth habit,

(c) forms semi-glossy medium green foliage,

(d) propagates well on its own roots, and

(e) is particularly suited for growing as ornamentation in a hanging basket;

substantially as herein shown and described.
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., theseed parent) of the new variety was the product of the pollination of the `Meiplarzon` variety (non-patented in the United States) and the `Meitristical` variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the newvariety was the `Katharina Zeimet` variety (non-patented in the United States). The parentage of the new variety can be summaried as follows:

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 posseses the following combination of characteristics:

(a) forms in abundance attractive small double pink blossoms,

(b) exhibits a hanging growth habit,

(c) forms semi-glossy medium green foliage,

(d) propagates well on its own roots, and

(e) is particularly suited for growing as ornamentation in a hanging basket .

The new variety well meets the needs of the horticultural society. It is particularly well-suited for use as attractive ornamentation when growing outdoors in a hanging pot.

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 characteristicsof the new variety are strictly transmissible from one generation to another.

The new variety has been named the `Meibrenec` 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 two yearsof age and were observed during November while growing on their own roots indoors at LeCannet 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 which precedes reference to the chart has been added to indicate the corresponding colors in more common terms. The description is based on two year-old specimens of the new variety which were observed during November while growing on their own roots indoors at LeCannet des Maures, Var, France.
