Abstract

A new and distinct shrub rose plant is provided that abundantly and substantially continuously forms attractive double blossoms that are white with a pink hue at the edges of the petals. The plant exhibits vigorous vegetation and a bushy and upright growth habit. The ornamental foliage is dark green with a matte finish. The blossoms are very fragrant. 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. Radfragwhite.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida shrub rose plant of the present invention was created during June 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 ‘Radbrite’ variety (U.S. Plant Pat. No. 17,391). The male parent (i.e., the pollen parent) of the new variety was the ‘Radell’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Radbrite’בRadell’.
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 shrub rose plant of the present invention possesses the following combination of characteristics:
    • (a) abundantly and substantially continuously forms attractive very fragrant double white blossoms with a pink hue at the edges of the petals,
    • (b) exhibits a bushy and upright growth habit,
    • (c) forms vigorous vegetation,
    • (d) forms attractive ornamental dark green foliage having a matte finish,
    • (e) exhibits good resistance to disease, and
    • (f) is well suited for providing attractive ornamentation in the landscape.
A new rose variety is provided having attractive fragrant white blossoms combined with substantially continuous blooming and good 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 new variety is particularly well suited for growing in the landscape. The new variety also can be readily distinguished from its ‘Radell’ parent in a number of respects. ‘Radell’ commonly forms larger clear medium pink blooms that are borne mostly one per stem. The leaflets of ‘Radell’ tend to be more pointed while those of the new variety tend to be smaller and more rounded. The new growth of ‘Radell’ is a noticeably colorful reddish-burgundy unlike that of the new variety. The fragrance of ‘Radell’ tends to be spicy unlike the citrus fragrance of the new variety. Also, the growth habit of the new variety tends to be somewhat more upright than that of the ‘Radell’ variety. The white blossoms contrast nicely with the dark green foliage having a matte finish.
The new variety of the present invention can be readily distinguished from its ancestors as well as from previously available varieties such as the ‘Radwhite’ variety (U.S. Plant Pat. No. 20,273). More specifically, the blossoms of the ‘Radbrite’ variety are pink with a yellow eye and a dissimilar climbing growth habit is displayed by such variety. The blossoms of the ‘Radwhite’ variety are initially light yellow and turn to white when mature.
The characteristics of the new variety have been found at Waso, 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 ‘Radfragwhite’, and will be marketed in the United States under the MILWAUKEE'S CALATRAVA 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 of the new variety in various stages of development. The illustrated rose plant of the new variety was approximately four years of age and was observed during July 2009 while growing outdoors near West Grove, Pa., U.S.A. The red hue at the edges of the petals is readily apparent on the blossoms present at the center and left.
DETAILED DESCRIPTION
The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart-1995 or equivalent), London, England. The description is based on the observation of two-year-old specimens of the new variety during July while growing outdoors in containers near West Grove, Pa., U.S.A.
