Climbing rose plant named ‘Radpetals’

Abstract

A new and distinct Climbing rose plant is provided that abundantly and substantially continuously forms attractive semi-double cup-shaped coral blossoms with yellow eyes. The plant exhibits vigorous and strong vegetation. The foliage is ornamental dark green with a semi-glossy finish on the upper surface. The lighter blossom coloration contrasts nicely with the dark green foliage. The disease resistance is excellent, particularly with respect to black spot, rust and mildews. The plant is well suited for providing attractive ornamentation.

Description

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

Varietal denomination: cv. Radpetals.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Climbing rose plant of the present invention was created in June 2005 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., seed parent) was the ‘Radbig’ variety (non-patented and unreleased breeder seedling), and the male parent (i.e., pollen parent) was the ‘Radfourth’ variety (non-patented and unreleased breeder seedling). The parentage can be summarized as follows:
‘Radbig’בRadfourth’.

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 cup-shaped coral blossoms with yellow eyes,
  • (b) exhibits a very bushy and climbing growth habit,
  • (c) forms vigorous and strong vegetation,
  • (d) forms attractive ornamental dark green foliage with a semi-glossy finish on the upper surface that contrasts well with the blossom coloration, (e) exhibits excellent disease resistance particularly with respect to black spot, rust and mildews, and
  • (f) is well suited for providing attractive ornamentation.

A new rose variety is provided displaying attractive cup-shaped coral blossoms with yellow eyes combined with substantially continuous blossoming and excellent 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 to cover a trellis, arbor or fence. Accordingly, the plant is particularly well suited for growing in the landscape where a climbing rose plant is desired.

The new variety can be readily distinguished from its ancestors upon an inspection of the blossoms. More specifically, the ‘Radbig’ parent variety forms dissimilar single blossoms having only five petals, and the ‘Radfourth’ variety forms dissimilar double blossoms combined with a shrub growth habit.

The new variety also can be readily distinguished from the ‘Radbrite’ variety (U.S. Plant Pat. No. 17,391) through an inspection of the blossoms. More specifically, the ‘Radbrite’ variety displays dissimilar single blossoms having only approximately seven to ten petals.

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 ‘Radpetals’, and will be marketed under the FRUITY PETALS Trademark.

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this character, typical specimens of the new variety. The illustrated rose plants of the new variety were approximately three years of age and were observed during May 2012 while growing outdoors on their own roots at West Grove, Pa., U.S.A.
