Rose plant--Meipoque variety

Abstract

A new and distinct variety of shrub rose plant is provided which forms in abundance single rose-carmine flowers of five petals having a white center. The new variety has a vigorous growth habit and is well-adapted for growing in the landscape where it reflowers well all season long. Attractive red fruits commonly are present on the new variety during the autumn-winter.

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 variety Meituraphar which is marketed in Europe under the trademark of Anne De Bretagne. The male parent (i.e., the pollen parent) of the new variety was the variety Meirisouru which is marketed in Europe under the trademark of Nirvana. The parents of the new variety are non-patented in the United States. The parentage of the new variety can be summarized as follows: Meituraphar.times.Meirisouru.

The seeds resulting from the above pollination were sown and 170 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 in abundance over an extended period of time attractive rose-carmine single flower blossoms of five petals having a white center,

(b) forms in the fall attractive red fruits,

(c) exhibits a vigorous growth habit,

(d) is hardy and relatively disease-resistant, and

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

The new variety meets the needs of the horticultural industry for virtually all uses. Since the new variety reflowers well without stopping all season long and the attractive red fruit which is formed in the fall imparts an added decorative effect, the new variety is particularly well-suited for growing in landscape situations. The exceptional vigor, floriferousness, and hardiness of the new variety are noteworthy.

The new variety has been found to undergo asexual propagation by a number of routes, including budding and grafting. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the Meipoque variety.

DETAILED DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology preceding the numbered references has been added to designate in common terms the corresponding colors. The description is based on one-year old specimens of the new variety during July while budded on Rosa froebelii understock and grown in a nursery at LeLuc, France.

Class: Shrub.

Plant:

Height.--Approximately 1.5 meters.
