Climbing rose plant named ‘Radmor’

Abstract

A new and distinct variety of rose plant is provided which forms in abundance on a substantially continuous basis attractive cuplike semi-double blossoms that are soft pink and finish to shell pink in coloration. The vegetation is vigorous and the growth habit is upright and climbing. Attractive ornamental green foliage having a semi-glossy appearance is formed. Excellent resistance with respect to blackspot is displayed. The hardiness of the new variety is excellent for a climber. The new variety is particularly well suited for growing as distinctive ornamentation in parks, gardens, and residential settings.

Description

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

Varietal denomination: cv. Radmor.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida climbing 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 female parent (i.e., the seed parent) was the ‘Radsbs’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was a salmon-colored Rugohybrid of the ‘Radspot’ variety (non-patented in the United States). The ‘Radspot’ variety is a seedling of the ‘Radbrite’ variety (U.S. Plant Pat. No. 17,391). The parentage of the new variety can be summarized as follows:
‘Radsbs’בRadspot’.

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 cuplike blossoms that are soft pink and finish to a shell pink coloration,
  • (b) exhibits an upright and climbing growth habit,
  • (c) forms vigorous vegetation,
  • (d) abundantly forms attractive ornamental green foliage with a semi-glossy appearance,
  • (e) exhibits excellent resistance to blackspot, and
  • (f) exhibits excellent cold hardiness.

The new variety displays a good repeat blooming character and its winter hardiness is outstanding for a climbing rose plant. The growth 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 attractive ornamentation 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 pink blossoms contrast nicely with the semi-glossy green foliage.

The new variety of the present invention can be readily distinguished from its ancestors. Unlike the new variety the ‘Radsbs’ variety displays a more bushy growth habit and forms smaller blossoms having more petals which are a yellow blend in coloration. Also, the ‘Radsbs’ variety tends to be somewhat less winter hardy than the new variety. The ‘Radbrite’ variety displays dissimilar salmon-pink blossoms with a yellow eye. The overall coloration of the new variety is much lighter and softer and is lacking a yellow eye.

The characteristics of the new variety have been found near West Grove, Pa., U.S.A. and elsewhere, 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 ‘Radmor’ and is being marketed under the MORNING MAGIC 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 the summer while growing on a support at Greenfield, Wis., 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 three-year-one specimens of the new variety during September while growing outdoors on their own roots near West Grove, Pa., U.S.A.
