Abstract

A new and distinct variety of landscape shrub rose plant is provided which forms in abundance on a substantially continuous basis attractive semi-double blossoms that are dark bright red in coloration. The vegetation is vigorous and the growth habit is round and bushy. Attractive ornamental glossy dark green foliage is formed. Superior disease resistance to blackspot is exhibited. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Botanical/commercial classification: Rosa hybrida/Shrub Rose Plant.
Varietal denomination: cv. Sprothrive.
SUMMARY OF THE INVENTION
The new variety of landscape shrub rose plant of the present invention was created by artificial pollination carried out at Bakersfield, Calif., U.S.A., 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 product of the cross of the ‘Meimonblan’ variety (U.S. Plant Pat. No. 12,579) and the ‘Scrivluv’ variety (non-patented in the United States). The ‘Scrivluv’ variety sometimes is known as the ‘Baby Love’ variety. The male parent (i.e., the pollen parent) of the new variety was the ‘Wekcisbako’ variety (U.S. Plant Pat. No. 18,552). The ‘Wekcisbako’ male parent incorporated the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836) as its male parent. The parentage of the present invention can be summarized as follows:
(‘Meimonblan’בScrivluv’)בWekcisbako’.
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 variety of landscape shrub rose plant of the present invention possesses the following combination of characteristics:
    • (a) abundantly and substantially continuously forms attractive semi-double blossoms that are dark bright red in coloration,
    • (b) exhibits a round and bushy growth habit,
    • (c) forms vigorous vegetation,
    • (d) forms attractive ornamental dark green foliage with a glossy finish, and
    • (e) exhibits superior resistance to blackspot.
A new rose variety is provided having attractive dark bright red blooms, combined with substantially continuous blooming and blackspot resistance. The blossom coloration approaches that of fire engine red.
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 residential landscapes. Accordingly, it is particularly well suited for growing in the landscape. The dark bright red blossoms contrast nicely with the glossy green foliage.
The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation at Wasco, Calif., U.S.A., such as budding, grafting, and vegetative propagation from one generation to another. Accordingly, the new variety can be asexually reproduced in a true-to-type manner.
The new variety has been named ‘Sprothrive’, and will be marketed under the THRIVE! trademark.
The new variety can be readily distinguished from its ancestors upon an inspection of the blossoms. More specifically, the ‘Meimonblan’ variety forms marigold orange blossoms. The ‘Scrivluv’ variety forms deep yellow blossoms. The ‘Wekcisbako’ variety forms red blossoms having single petalage unlike the new variety. The ‘Radrazz’ variety forms blossoms of lighter red coloration. For instance, the dark bright red blossom coloration of the new variety approaches that of Red Group 46A while that of the ‘Radrazz’ variety commonly is between Red Group 53C and Red Group 53D of The R.H.S. Colour Chart of The Royal Horticultural Society. During observations to date, the blackspot resistance of the new variety, while superior, has been somewhat less than that of the ‘Radrazz’ variety.
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. The illustrated plant was approximately three years of age and was being grown outdoors on its own roots in the field 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). The description is based on the observation of three-year-old specimens of the new variety during June while grown outdoors on their own roots at West Grove, Pa., U.S.A.
