Shrub rose plant named ‘Radsouththree’

Abstract

A new and distinct shrub rose plant is provided that abundantly forms attractive single dark pink blossoms that finish to a coral red coloration. The plant exhibits vigorous vegetation and a compact and bushy growth habit. The foliage is dark green with a glossy upper surface. The dark pink blossom coloration contrasts nicely with the dark green foliage. The disease resistance is excellent, particularly with respect to black spot, rust, and mildews. The plant is well suited for providing attractive ornamentation in in the landscape.

Description

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

Varietal denomination: cv. Radsouththree.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant of the present invention was created at Greenfield, Wis., U.S.A. The seed that produced the new variety of landscape shrub rose was obtained by the cross of unreleased and unnamed breeding plants (each non-patented in the United States) of unknown origin. No further definitive information concerning the identity of the parents is available.

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 forms attractive single dark pink blossoms having yellow centers that finish to a coral red coloration,
  • (b) exhibits a compact and bushy growth habit,
  • (c) forms vigorous vegetation,
  • (d) forms attractive dark green foliage that is glossy on the upper surface and contrasts well with the blossom coloration,
  • (e) exhibits excellent disease resistance particularly with respect to black spot, rust, and mildews, and
  • (f) is well suited for growing as attractive ornamentation in the landscape.

A new rose variety is provided having attractive single dark pink blossoms with yellow centers that finish to a coral red coloration combined with substantially continuous blooming, a compact growth habit, and excellent disease 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. Accordingly, the plant is particularly well suited for growing in the landscape. The dark pink flower coloration combined with the glossy dark green foliage is particularly attractive.

The new variety of the present invention can be readily distinguished from other shrub rose plants including the ‘Sprothrive’ variety (U.S. Plant Pat. No. 23,549) through an inspection of the blossoms. For instance, the single blossoms of dark pink coloration of the new variety are dissimilar to the dark red blossoms of the ‘Sprothrive’ variety.

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 ‘Radsouththree’, and will be marketed under the FRUIT PUNCH trademark.

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 blossoms and foliage of the new variety. The illustrated rose plants of the new variety were approximately two years of age and were observed during May while growing outdoors on their own roots at West Grove, Pa., U.S.A.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—1995 Edition or equivalent), London, England. The description is based on the observation of two-year-old specimens of the new variety during October while growing outdoors on their own roots at West Grove, Pa., U.S.A.
