Abstract

A new and distinct shrub rose plant is provided that abundantly and substantially continuously forms attractive single pink blossoms. The plant exhibits vigorous vegetation and a mounding and bushy growth habit. The ornamental foliage is dark green with a semi-glossy finish. Good resistance to blackspot has been experienced. The plant is well suited for growing as attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Shrub Rose Plant.

Varietal denomination: cv. Radsouth.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant of the present invention was created during 2002 at Greenfield, Wis., U.S.A., 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) was the ‘Radrise2’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the ‘Radcor’ variety (U.S. Plant Pat. No. 17,346). The parentage of the new variety can be summarized as follows:
‘Radrise2’×‘Radcor’.

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 Landscape Shrub rose plant of the present invention possesses the following combination of characteristics:

- (a) abundantly and substantially continuously forms attractive single pink blossoms,
- (b) exhibits a mounding and bushy growth habit,
- (c) forms vigorous vegetation,
- (d) forms attractive ornamental dark green foliage with a semi-glossy finish, and
- (e) exhibits excellent resistance to blackspot.

A new rose variety is provided which bears attractive single pink blossoms combined with substantially continuous blooming and blackspot resistance.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. The new variety is particularly well suited for providing attractive ornamentation in the landscape. The pink blossom color contrasts nicely with the semi-glossy dark green foliage.

The new variety of the present invention also can be readily distinguished from its ancestors. More specifically, the ‘Radcor’ variety displays lighter coral pink blossoms, with a strong yellow center, while the blossoms of the new variety are darker pink with a slight cream to yellow center. The ‘Radrise2’ variety displays larger blossoms that are lighter in color and a climbing growth habit unlike the new variety. The new variety of the present invention also can be readily distinguished from the ‘Radcon’ variety (U.S. Plant Pat. No. 15,070) upon an inspection of the blossoms. More specifically, the blossoms of the new variety are considerably darker pink than those of the ‘Radcon’ variety.

Additionally, the new variety can be readily distinguished from the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836) and the ‘Meipotal’ variety (U.S. Plant Pat. No. 8,841) upon an inspection of the blossom color. The blossoms of the ‘Radrazz’ variety are cherry red in coloration, and those of the ‘Meipotal’ variety are pink with white eyes.

The characteristics of the new variety have been found at Wasco, Calif., U.S.A., to be homogeneous and stable and to be strictly transmissible by asexual propagation, such as budding, grafting, and the rooting of cuttings from one generation to another. The new variety reproduces in a true-to-type manner by such asexual propagation.

The new variety has been named ‘Radsouth’.

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, a row of typical flowering plants of the new variety. The illustrated rose plants of the new variety were approximately two years of age and were observed during June while growing outdoors near West Grove, Pa., U.S.A.

DETAILED DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. The description is based on the observation of two-year-old specimens of the new variety during June while growing outside on their own roots near West Grove, Pa., U.S.A.
