Abstract

A new and distinct variety of landscape shrub rose plant is provided which forms in abundance on a substantially continuous basis attractive red-purple blossoms commonly bearing approximately 13 to 15 petals. The new variety is a spontaneous mutation of unknown causation of the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836) that forms vivid red blossoms which commonly display approximately 10 petals. The vegetation is vigorous and the growth habit is bushy and rounded. The foliage is very ornamental, dark green, and semi-glossy and contrasts nicely with the red-purple blossom coloration. Excellent resistance to blackspot is displayed. The new plant is particularly well suited for pot forcing under greenhouse growing conditions to form an attractive gift plant.

Description

Botanical/commercial classification: Rosa hybrida/Shrub Rose Plant.
Varietal denomination: cv. Meigadraz.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida landscape shrub rose plant of the present invention was discovered as a branch mutation during June 2000 while growing among a block of rose plants of the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836) growing outdoors at Le Cannet des Maures, Var, France. I was attracted to the new variety primarily because of its distinctive red-purple blossom coloration that was unlike that of the parental variety. The new variety is believed to be a spontaneous naturally-occurring mutation of the ‘Radrazz’ variety of unknown causation. Had I not discovered and preserved the original plant of the new variety it would have been lost to mankind.
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 red-purple blossoms commonly bearing approximately 13 to 15 petals on average unlike the vivid red blossoms of the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836),
    • (b) exhibits a bushy and rounded growth habit,
    • (c) forms vigorous vegetation,
    • (d) forms attractive very ornamental dark green semi-glossy foliage, and
    • (e) displays excellent resistance to blackspot.
The new rose variety has a propensity for everblooming combined with blackspot resistance.
The new variety of the present invention can be readily distinguished from the parental ‘Radrazz’ variety through an inspection of the blossoms. More specifically, the new variety displays red-purple blossoms having approximately 13 to 15 petals on average rather than vivid red blossoms having approximately 10 petals on average that are displayed by the parental ‘Radrazz’ variety. Also, the new variety of the present invention readily also can be distinguished from the ‘Radyod’ variety (U.S. Plant Pat. No. 14,700) and the ‘Radcon’ variety (U.S. Plant Pat. No. 15,070) which are other mutations of the ‘Radrazz’ variety. More specifically, the blossoms of the ‘Radyod’ variety are light pink, and the blossoms of the ‘Radcon’ variety a darker pink than those of the ‘Radyod’ variety. The blossoms of the new variety of the present invention are more red-purple, and commonly possess more petals than the blossoms of the ‘Radyod’ variety.
The new variety well meets the needs of the horticultural industry, and is particularly well suited for pot forcing under greenhouse growing conditions to form an attractive gift plant. The red-purple blossoms contrast nicely with the semi-glossy dark green foliage.
The characteristics of the new variety have been found at Le Cannet des Maures, Var, France, to be homogeneous and stable and are strictly transmissible by asexual propagation such as budding, grafting, and the use of cuttings from one generation to another carried out at such location.
The new variety has been named the ‘Meigadraz’ variety.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph of FIG. 1 shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, a typical specimen showing the attractive red-purple flowers of the new variety at various stage of maturity. The rose plants were approximately two years of age and were grown in the ground outdoors on Rosa froebelii rootstock at Le Cannet des Maures, Var, France.
 DETAILED DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart).
