Abstract

A new and distinct variety of floribunda rose plant, herein referred to by its cultivar name, ‘Sproflored’, is provided which forms abundantly on a substantially continuous basis attractive, cup shaped deep red blossoms. Attractive, glossy, dark green foliage is formed, which contrasts beautifully with the blossoms. The vegetation is vigorous and the growth habit is very bushy and rounded. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘Sproflored’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida floribunda rose plant was created during April of 2008 in Bakersfield, Calif., U.S.A., 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 seedling (non-patented). The male parent (i.e., the pollen parent) was the ‘Sprothrive’ variety (U.S. Plant Pat. No. 23,549).

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

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 Floribunda rose plant of the present invention possesses the following combination of characteristics:

- (a) forms attractive, cup shaped, deep red colored blossoms abundantly and substantially continuously,
- (b) displays a very bushy and rounded growth habit,
- (c) forms vigorous vegetation,
- (d) provides attractive ornamental glossy, dark green foliage, and
- (e) exhibits good disease resistance.

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 in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the unnamed seedling female parent (i.e., the seed parent) displays peach colored blossoms, whereas the new variety displays deep red colored blossoms and the ‘Sprothrive’ variety (i.e., the pollen parent) provides less petals and is less compact in habit compared to the new variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIBIONEL’ variety (U.S. Plant Pat. No. 15,878) displays less petal, provides a larger flower size, and exhibits foliage that is less glossy compared to the new variety.

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

The new variety has been named ‘Sproflored’.

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 of the new variety. The rose plant of the new variety was approximately three years of age and was observed during July 2016 while growing on its own roots and growing outdoors at Watsonville, Calif., U.S.A.

FIG. 1—illustrates a specimen of a plant with blooms at varying stages of opening and is in a field planted with other roses.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition), London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of three-year-old specimens of the new variety during July while growing on their own roots at Cochranville, Pa., U.S.A.
