Abstract

A new and distinct variety of rose plant is provided which forms in abundance on a substantially continuous basis attractive semi-double blossoms wherein the coloration is magenta red to light pink suffused with cream-white towards the center. The vegetation is vigorous and the growth habit is upright and climbing. Attractive ornamental medium green foliage having a semi-glossy aspect is formed. During observations to date the disease resistance has been excellent, particularly with respect to blackspot. The cold hardiness of the new variety also is excellent, particularly for a climbing rose. The new variety is particularly well suited for growing as distinctive ornamentation in parks, gardens, and residential settings. Instead of a climber, the plant can alternatively be trimmed and grown as a compact rose bush in the absence of support.

Description

Botanical/commercial classification: Rosa hybrida/Climbing Rose Plant.
Varietal denomination: cv. Radcancan.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida shrub rose plant of the present invention was created 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 cross was carried out during July 2001. The female parent (i.e., the seed parent) was the ‘Radcovery’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the ‘Radcotee’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Radcovery’בRadcotee’.
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 climbing rose plant of the present invention possesses the following combination of characteristics:
    • (a) abundantly and substantially continuously forms attractive semi-double blossoms that are magenta red to light pink suffused with cream-white towards the center,
    • (b) exhibits an upright and climbing growth habit,
    • (c) forms vigorous vegetation,
    • (d) forms attractive ornamental medium green foliage with a semi-glossy aspect,
    • (e) exhibits excellent resistance to blackspot, and
    • (f) exhibits excellent cold hardiness for a climbing rose.
The new variety displays a good repeat blooming character. The winter hardiness is above average for a rose of this class. The growth habit is very vigorous and the canes commonly are of medium to heavy caliper for the class.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as an attractive climber in parks, gardens, public areas, and in residential settings. It alternatively can be trimmed and grown as a compact rose bush in the absence of support. The new variety is particularly well suited for providing attractive ornamentation in the landscape. The blossom coloration contrasts nicely with the semi-glossy medium green foliage.
The new variety of the present invention can be readily distinguished from its ancestors, as well as other climbing rose varieties that are available to others for comparison, such as the ‘Radwin’ variety (U.S. Plant Pat. No. 19,310) and the ‘Radbrite’ variety (U.S. Plant Pat. No. 17,391). More specifically, the blossoms of the ‘Radwin’ variety are entirely red in coloration, and the blossoms of the ‘Radbrite’ variety are pink with a yellow 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 ‘Radcancan’ and is being marketed under the CANCAN 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, a typical specimen of the new variety. A mature flowering plant is shown during July while growing with support in the garden of its originator at Greenfield, Wis., U.S.A. The attractive blossoms, floral buds, and foliage are displayed.
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 three-year-old specimens of the new variety during July while growing outdoors on their own roots near West Grove, Pa., U.S.A.
