Shrub rose plant named ‘BAInder’

Abstract

A new and distinct variety of landscape shrub rose plant is provided which forms on a continuous basis attractive double red blended with pink blossoms. The blossoms are borne singly and in loose clusters. The plant exhibits a compact, upright and bushy growth habit, satiny medium green foliage, and excellent tolerance to Black Spot and Powdery Mildew. The attractive medium green foliage contrasts nicely with the red blended with pink blossom coloration. A tough rose plant of good hardiness is provided. The plant can be grown to advantage as a specimen, border planting, or as a mass planting.

Description

Botanical commercial classification: Rosa hybrida/Shrub Rose Plant.

Varietal denomination: cv. ‘BAInder’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant was created at Yamhill, Oreg. during 1993 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 an unnamed plant designated 4-40A. Such female parent was an unreleased plant from our breeding program and was not available to the public. The male parent (i.e., the pollen parent) was the ‘Meipitac’ variety (U.S. Plant Pat. No. 7,783). The ‘Meipitac’ variety is marketed under the CAREFREE WONDER trademark. The parentage of the new variety can be summarized as follows:
4-40AבMeipatac’.

The seeds resulting from the above pollination were sown and plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification during 1996 of a single plant of the new variety having the distinctive ornamental characteristics hereafter described.

It was found that the new variety of the present invention:

• • (a) exhibits a compact, upright and bushy growth habit,
  • (b) forms continuously attractive double red blended with pink blossoms,
  • (c) forms satiny medium green adult foliage,
  • (d) displays excellent tolerance to Black Spot and Powdery Mildew; and
  • (e) is particularly well suited for growing as attractive ornamentation in parks and gardens.

The red buds open to the medium red blended with pink blooms that contrast nicely with the medium green foliage. The official American Rose Society color of the blooms is medium red. A tough shrub rose plant having good hardiness is provided.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage anywhere in the landscape where attractive ornamentation is desired. The distinctive blossoms are displayed throughout the summer on a continuous basis. The plant can be grown as a specimen, border planting, or as a mass ground cover.

The new variety can be readily distinguished from other varieties including its parental varieties. More specifically, the ‘4-40A’ variety forms deep orange double blossoms having approximately 30 petals on average, and the ‘Meipitac’ variety forms pointed buds and pink double blossoms having approximately 26 petals on average. The ‘MORten’ variety (U.S. Plant Pat. No. 8,199) forms pointed buds wherein the opening flower is medium red with a lighter red reverse and commonly assumes a greater height of approximately 1.5 m. Such ‘MORten’ variety sometimes is known as the ‘Linda Campbell’ variety. The ‘Henry Kelsey’ variety (non-patented in the United States) forms dark red opening flowers changing to medium red having approximately 28 petals and commonly assumes a greater height of approximately 1.8 m.

The new variety has been found to undergo asexual propagation by budding on an understock beginning in April 1994 and by the rooting of cuttings. ‘Dr. Huey’ rootstock was used during the budding. Such asexual propagation by these techniques at Yamhill, Oreg., St. Paul, Minn., and at Phoenix, Ariz. has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. The new variety grows well on its own roots.

Initially the new plant was designated 93A130-14P. The new variety subsequently has been named the ‘BAInder’ variety, and currently is being marketed while using the GARDEN JUBILEE and HOT WONDER trademarks.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 rose plants of the new variety had been propagated by the rooting of cuttings, were approximately three years of age, and were being grown outdoors at St. Paul, Minn. during the 2002 season.

FIG. 1 illustrates a row of typical plants of the new variety while abundantly blooming. The attractive medium foliage also is shown.

FIG. 2 illustrates a closer view of typical bud and blossoms of the new variety at various stages of opening.

FIG. 3 illustrates a typical open blossom of the new variety wherein the lighter coloration of the under petal surface is apparent at the center of the bloom.

FIG. 4 illustrates a typical fully mature blossom and foliage of the new variety. The yellow basal petal spot and the stamens and pistils also are visible.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). Common color terms are to be accorded their ordinary dictionary significance. The description is based on the observation of two and three year-old plants while grown outdoors on their own roots during June and July 2002 and 2003 at St. Paul, Minn., and June 2003 at Yamhill, Oreg.
