Abstract

A new and distinct variety of shrub rose plant, referred to by its cultivar name, ‘Radmeadow’, is described. The new variety forms in abundance on a substantially continuous basis, bicolor cream and pink-colored blossoms. The growth habit is very bushy and rounded. Semi-glossy, dark green ornamental foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘Radmeadow’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was Spring of 2024 through the Prides Corner Farms website and Heirloom Roses website. The first sale or offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of shrub rose plant of the present invention was created by controlled breeding during June 2013, in Milwaukee, Wisconsin 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) of the new variety was an unnamed breeder seedling (not patented). The male parent (i.e., the pollen parent) of the new variety was the ‘KORfloci08’ variety (U.S. Plant Pat. No. 19,362).

The parentage of the new variety can be summarized as follows:
unnamed breeder seedling x ‘KORfloci08’

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.

The new variety has been found to undergo asexual propagation in Wasco, California and Cochranville, Pennsylvania by a number of routes such as vegetative cuttings. Asexual propagation techniques in Wasco, California and Cochranville, Pennsylvania, such as vegetative cuttings, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of shrub rose plant of the present invention possesses the following combination of characteristics:

- (a) forms bicolor cream and pink colored blossoms,
- (b) exhibits a very bushy and rounded growth habit, and
- (c) forms semi-glossy and dark green colored foliage.

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 residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the new variety provides bicolor cream and pink colored blossoms and stronger peduncles compared to the pale pink colored blossoms of the unnamed breeder seedling parent (i.e., the seed parent). Additionally, the new variety displays a slightly larger growth habit, longer bloom life, and bicolor cream and pink colored flowers, compared to the ‘KORfloci08’ variety (i.e., the pollen parent) which displays orange-red colored flowers. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the new variety displays cream-colored flowers with pink margins compared to the white colored blossoms of the ‘Meiradena’ variety (U.S. Plant Pat. No. 26,790).

The new variety has been named the ‘Radmeadow’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 and blossoms of the new variety. The illustrated rose plant of the new variety was approximately two years of age and was grown outdoors on its own roots in a one-gallon container in Cochranville, Pennsylvania in May 2024.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2015 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms and The R.H.S. Colour Chart designation used herein represents the closest color observed on the majority of the specified botanical feature. The description is based on a two-years-old specimen of the new variety, observed during September 2023, while growing in a three-gallon container on its own roots in a greenhouse in Cochranville, Pennsylvania.
