Abstract

A new and distinct shrub rose plant is provided that abundantly forms in clusters attractive small single medium pink finishing to light pink blossoms that drop their petals well upon full maturity. The plant exhibits vigorous vegetation and an upright and bushy growth habit. The foliage is dark green with a semi-glossy finish on the upper surface. The disease resistance is excellent, particularly with respect to Black Spot, Powdery Mildew, and Rust. The plant is well suited for growing as attractive ornamentation in in the landscape as a hedge or mass planting. Alternatively, the plant can be grown in containers.

Description

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

Varietal denomination: cv. Radcleome.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant of the present invention was created during 2001 at Greenfield, Wis., U.S.A., by open pollination in a rose garden setting at my home in the hope that desired characteristics would be displayed in the progeny. The female parent (i.e., the seed parent) was the ‘Angel Rose’ variety (non-patented in the United States). The female parent is a Polyantha rose and sometimes is identified as ‘Minima’. The male parent (i.e., the pollen parent) is unknown. The parentage of the new variety can be summarized as follows:
‘Angel Rose’×Unknown.

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 in clusters attractive small single medium pink finishing to light pink blossoms that drop their petals well upon fully maturity,
- (b) exhibits an upright and bushy growth habit,
- (c) forms vigorous vegetation,
- (d) forms attractive dark green foliage with a semi-glossy finish on the upper surface that contrasts well with the blossom coloration,
- (e) exhibits excellent disease resistance, and
- (f) is well suited for growing as attractive ornamentation in the landscape.

A new rose variety is provided which bears attractive single light blossoms combined with excellent disease resistance, particularly with respect to Black Spot, Powdery Mildew, and Rust. Commonly more than 50 blooms per stem are formed which attract bees. The plant has been found to develop well regardless of the mode used for asexual propagation.

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 growing as a hedge or as a mass planting. The new variety also can be grown in containers.

The new variety of the present invention also can be readily distinguished from its ‘Angel Rose’ parent as well as from other Polyantha hybrid varieties, such as the ‘Harpballred’ variety (U.S. Plant Pat. No. 24,437). More specifically, the ‘Angel Rose’ female parent forms semi-double to double blossoms having hues of pink to white. The ‘Harpballred’ variety has a generally smaller stature and forms dissimilar bright red blossoms with a white eye.

The characteristics of the new variety have been found at Wasco, Calif., U.S.A., and near West Grove, Pa., 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 ‘Radcleome’, and is being marketed under the LOOK-A-LIKES and PHLOXY BABY trademarks.

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 flowering rose plants of the new variety. The illustrated rose plants of the new variety were approximately three years of age and were observed during June while growing outdoors on their own roots near West Grove, Pa., U.S.A.

DETAILED BOTANICAL DESCRIPTION
