Shrub rose plant named `Radrazz`

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

SUMMARY OF THE INVENTION
 The new variety of Rose hybrida landscape shrub rose plant of the present
 invention was created 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 a seedling of the `Carefree Beauty` variety (U.S. Plant Pat.
 No. 4,225). The male parent (i.e., the pollen parent) of the new variety
 was a seedling of the `Razzle Dazzle` variety (U.S. Plant Pat. No. 3,995).
 The parentage of the new variety can be summarized as follows:
EQU `Carefree Beauty` Seedling.times.`Razzle Dazzle` seedling.
 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 indentification 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 single
 blossoms that are red in coloration,
 (b) Exhibits a round and bushy growth habit,
 (c) Forms vigorous vegetation,
 (d) Forms attractive ornamental green foliage with a satiny finish, and
 (e) Exhibits excellent resistance to blackspot.
 A new rose variety is provided having attractive red blooms, combined with
 substantially continuous blooming and blackspot resistance. The blooming
 cycle is believed to be one of the longest observed to date for a rose
 plant.
 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 red blossoms contrast nicely
 with the satiny green foliage.
 The characteristics of the new variety have been found at Wasco, Calif. to
 be homogeneous and stable and are strictly transmissible by asexual
 propagation such as budding, grafting, and cuttage from one generation to
 another.
 The new variety has been named the `Radrazz` variety.
