Floribunda rose plant named ‘Radprov’

Abstract

A new and distinct Floribunda rose plant is provided that abundantly and substantially continuously forms attractive very double old-fashioned blossoms that are pink with undertones of lavender. The blossom fragrance is very strong and commonly is reminiscent of fresh citrus. The plant exhibits vigorous vegetation and an upright and bushy growth habit. The foliage is dark green with a semi-glossy finish. Good resistance to blackspot has been experienced. The plant is well suited for growing as attractive ornamentation in parks and gardens.

Description

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

Varietal denomination: cv. Radprov.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant of the present invention was created during 2003 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 ‘Wekbipuhit’ variety (U.S. Plant Pat. No. 11,513). The male parent (i.e., the pollen parent) of the new variety was the ‘Radmis’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Wekbipuhit’בRadmis’.

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 Floribunda rose plant of the present invention possesses the following combination of characteristics:

• • (a) abundantly and substantially continuously forms attractive very double old-fashioned blossoms that are pink with undertones of lavender and display a strong fragrance,
  • (b) exhibits an upright and bushy growth habit,
  • (c) forms vigorous vegetation,
  • (d) forms attractive dark green foliage with a semi-glossy finish, and
  • (e) exhibits good resistance to blackspot.

A new rose variety is provided which bears fragrant old-fashioned pink blossoms combined with substantially continuous blooming and blackspot 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. The new variety is particularly well suited for providing attractive ornamentation in the landscape. The pink blossoms contrast nicely with the semi-glossy dark green foliage.

The new variety of the present invention also can be readily distinguished from its ancestors. For instance, the ‘Wekbipuhit’ variety forms magenta-colored blossoms having a substantially lesser number of petals than the new variety. The ‘Radmis’ variety forms semi-double blossoms that are peach with tones of yellow and pink in coloration and displays a lower spreading growth habit. When the new variety is compared to the ‘Meitripine’ variety (U.S. Plant Pat. No. 22,318, granted Dec. 13, 2011), it is found that the ‘Meitripine’ variety forms lavender-colored blossoms also having a substantially lesser number of petals than the new 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 ‘Radprov’ and will be marketed in the United States under the ORCHID ROMANCE 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. The illustrated rose plant of the new variety was approximately two years of age and was observed during June while growing outdoors on its own roots at West Grove, PA., U.S.A.

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 June while growing outdoors on their own roots at West Grove, Pa., U.S.A.
