Shrub rose plant named ‘Spromel’

Abstract

A new and distinct variety of shrub rose plant is provided which forms in abundance on a substantially continuous basis attractive semi-double blossoms that are orange to apricot with red coloration toward the center of the blossoms. The vegetation is vigorous and strong and the growth habit is upright and bushy. Attractive ornamental glossy dark green foliage is formed. The plant is particularly well suited for growing in a Western landscape. Distinctive ornamentation is provided.

Description

Botanical/commercial classification: Rosa hybrida/Shrub Rose Plant.

Varietal denomination: cv. Spromel.

SUMMARY OF THE INVENTION

The new variety of landscape shrub rose plant of the present invention was created by artificial pollination carried out in April/May 2008 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. Each parent possessed a complex parentage as indicated hereafter. More specifically, the parentage of the non-patented female parent (i.e., seed parent) can be summarized as follows: {‘MORtoday’×[‘Geisha’×(‘KINbo’בMacivy’)]}בSPRoimpress’. The male parent (i.e., pollen parent) was the ‘Sprolych’ variety (U.S. Plant patent application Ser, No. 13/998,618, filed Nov. 18, 2013). The ‘SPRoimpress’ variety is the subject of U.S. Plant Pat. No. 21,708. The other ancestoral plants of the female parent are non-patented in the United States.

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

• • (a) abundantly and substantially continuously forms attractive large semi-double blossoms that are orange to apricot with red coloration toward the center of the blossoms,
  • (b) exhibits an upright and bushy growth habit,
  • (c) forms vigorous and strong vegetation,
  • (d) forms attractive ornamental dark green foliage with a glossy finish, and
  • (e) is well suited for providing distinctive ornamentation.

A new rose variety is provided having attractive multi-colored blossoms, combined with substantially continuous blooming. The plant reblooms well and displays an attractive bushy growth habit.

The new variety well meets the needs of the horticultural industry particularly when grown in the Western landscape. It can be grown to advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes. The lavender and red blossom coloration contrasts nicely with the medium green foliage.

The new variety can be readily distinguished from its parental plants. More specifically, the female parent is a vigorous non-Hulthemia rose that displays a considerably smaller growth habit, and forms yellow-colored blossoms. The male parent displays a compact growth habit and forms ivory-cream-colored blossoms with a larger central blotch.

The new variety also can be readily distinguished from the ‘Sprolem’ variety (U.S. Plant Pat. No. 23,580), as well as other plants in its ancestry identified hereafter. More specifically, the ‘Sprolem’ variety forms bright yellow blossoms. The ‘MORtoday’ variety displays pink blossoms with lavender at the base. The ‘Geisha’ variety displays mauve blossoms. The ‘KINbo’ variety forms double deep yellow blossoms. The ‘Macivy’ variety displays very double apricot blossoms. The ‘SPRoimpress’ variety displays dark yellow blossoms. The ‘Orangeade’ variety displays orange to orange-red blossoms. The ‘Auscot’ variety forms very large very double yellow blossoms with dark pink at the base. The ‘WEKfabpur’ variety forms purple blossoms with a lighter under surface. The ‘SCRivluv’ variety displays single deep yellow blossoms. It is recognized that Hulthemia roses generally bloom only once a year and generally display an unattractive growth habit.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation by the use of cuttings from one generation to another at Wasco, Calif., U.S.A. Accordingly, the new variety can be asexually reproduced in a true-to-type manner.

The new variety has been named ‘Spromel’, and will be marketed under the EYCONIC and MELON LOMONADE trademarks.

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, typical blossoms, buds, and foliage of the new variety. The illustrated plant was approximately two years of age and was growing during September, 2011 outdoors on its own roots in the field at Wasco, Calif., U.S.A.

DETAILED DESCRIPTION

The description is based on the observation of two-year-old specimens of the new variety during May while growing on their own roots in a greenhouse at West Grove, Pa., U.S.A.
