Floribunda rose plant named ‘SPROLEMANGO’

Abstract

A new and distinct variety of Floribunda Rose plant, herein referred to by its cultivar name, ‘SPROLEMANGO’, is provided which forms in abundance on a substantially continuous basis attractive, cup-like apricot colored blossoms with a red center. The vegetation is vigorous and the growth habit is very bushy and compact. Attractive, glossy, dark green foliage is formed. The disease resistance is good. The new variety is well suited for proving attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘SPROLEMANGO’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created by artificial pollination in April, 2011 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 an unnamed and unreleased seedling. The male parent (i.e, the pollen parent) was an unnamed and unreleased seedling.

The parentage of the new variety can be summarized as follows:
unnamed seedling x unnamed 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 identification of a single plant of the new variety.

It was found that the new variety of Floribunda rose plant of the present invention:

• • (a) abundantly and substantially continuously forms attractive, semi-double, cuplike shaped, apricot colored blossoms with red center,
  • (b) forms a very bushy and compact growth habit,
  • (c) has vigorous vegetation,
  • (d) forms attractive ornamental glossy, dark green foliage,
  • (e) exhibits good tolerance to diseases, and
  • (f) is well suited for providing attractive ornamentation.

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 female parent (i.e., the seed parent) displays yellow colored blooms without a red center, whereas the new variety displays apricot colored blooms with a red center. Additionally, the new variety can be readily distinguished from other Floribunda roses, such as the ‘Spromel’ variety (U.S. Plant Pat. No. 25,125) in that the new variety displays a compact growth habit and is smaller than the ‘Spromel’ variety, which displays an upright growth habit.

The new variety has been found to undergo asexual propagation in Wasco, Calif., U.S.A by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in Wasco, Calif., U.S.A. 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 ‘SPROLEMANGO’.

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, a typical specimen of the plant parts of the new variety. The rose plant of the new variety was approximately two years of age and was observed during July 2017 while budded on its own roots and growing outdoors at West Grove, Pa., U.S.A.

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, 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 two-year-old specimens of the new variety during July while growing in a container on its own roots and growing outdoors at West Grove, Pa., U.S.A.
