Abstract

A new and distinct variety of rose plant is provided which forms in abundance on a substantially continuous basis attractive single to semi-double blossoms that are coral in coloration with substantial irregular cream-to-yellow striping. The vegetation is vigorous and the growth habit is upright and climbing. Attractive ornamental medium green foliage having a satiny finish is displayed. During observations to date the disease resistance has been good, particularly with respect to blackspot. The cold hardiness of the new variety also is excellent, particularly for a climbing rose. The new variety is 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. Radfifth.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida 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 June 1999. The female parent (i.e., the seed parent) was the ‘Meioffic’ variety (U.S. Plant Pat. No. 9,998). The male parent (i.e., the pollen parent) of the new variety was the ‘Wekroalt’ variety (U.S. Plant Pat. No. 11,518). The ‘Meioffic’ variety is being marketed under the JOHANN STRAUSS trademark, and the ‘Wekroalt’ variety is being marketed under the FOURTH OF JULY trademark. The parentage of the new variety can be summarized as follows:
‘Meioffic’בWekroalt’.
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 single or semi-double blossoms that are coral in coloration with substantial irregular cream-to-yellow striping,
    • (b) exhibits an upright and climbing growth habit,
    • (c) forms vigorous vegetation,
    • (d) forms attractive ornamental satiny medium green foliage,
    • (e) exhibits good 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 noteworthy for a climbing rose plant. The growth habit is very vigorous and the canes are medium in 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 wherever it is grown. The blossom coloration contrasts nicely with the satiny medium green foliage.
The new variety of the present invention can be readily distinguished from its ancestors, as well as other climbing rose varieties. More specifically, the ‘Meioffic’ variety parent is a Floribunda rose which exhibits Orient Pink blossoms suffused with Aureolin Yellow on the upper surface and Dawn Pink suffused with Aureolin Yellow on the under surface, and the ‘Wekroalt’ variety parent exhibits red blossoms striped with white. Also, the new variety of the present invention can be readily distinguished from the ‘Radbrite’ variety (U.S. Plant Pat. No. 17,391) and the ‘Radmor’ variety (U.S. Plant Pat. No. 19,433). The blossoms of the ‘Radbrite’ variety are pink with a yellow eye, and the blossoms of the ‘Radmor’ variety are soft pink and finish to shell pink in coloration.
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 ‘Radfifth’ and is being marketed under the CITRUS BURST trademark.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph shows from above, as nearly true as it is reasonably possible to make the same in a color illustration of this character, a typical flowering plant of the new variety. The illustrated rose plant was approximately two years of age and is depicted during the month of June while growing near West Grove, Pa., U.S.A. The attractive multi-colored blossoms in various stages of development and satiny green foliage are shown.
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 May while growing outdoors in containers near West Grove, Pa., U.S.A.
