USPP16276P3 - Shrub rose plant named ‘NOA250092’ - Google Patents

Abstract

A new and distinct variety of rose plant of the shrub class particularly well suited for growing as an attractive ornamentation to the landscape is disclosed. The plant is characterized by its numerous, attractive soft pink blossoms, whose attractive appearance is retained on aging; its bright orange stamens, which contrast attractively with soft pink of the petals; its upright, dense, and compact growth habit; its attractive dark green foliage; and its excellent disease resistance.

Description

FIELD OF THE INVENTION

This invention relates to a new and distinct variety of rose plant of the shrub rose class.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the shrub class, which is particularly well suited for growing as an attractive ornamentation to the landscape. The varietal denomination of this new and distinct variety of rose plant is ‘NOA250092’.

By cross pollination of a Noack Rosen Seedling (unpatented in the United States), which has soft pink single blooms, with the variety known as ‘Blühendes Barock’ (variety: NOAbell) (Noack Rosen, 1997, unpatented in the United States), a floribunda rose with medium pink blooms, I have produced a new and improved rose variety which is distinguished from all other rose varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein:

• • (1) its numerous, attractive soft pink blossoms, whose attractive appearance is retained on aging;
  • (2) its bright orange stamens, which contrast attractively with soft pink of the petals;
  • (3) its upright, dense, and compact growth habit;
  • (4) its attractive dark green foliage; and
  • (5) its excellent disease resistance.

Asexual reproduction of this new variety was first performed in Gütersloh, Germany. Asexual reproduction of this new variety by budding and by cuttings shows that the foregoing and all other characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE ILLUSTRATIONS

The accompanying illustrations show typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

FIG. 1 shows typical flowers of this new variety, in which the bright orange stamens and pollen contrasts attractively with soft pink of the petals.

FIG. 2 shows typical buds, leaves and flowers of this new variety.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with a Royal Horticulture Society Colour Chart (R.H.S.C.C.), except where ordinary dictionary significance of color is indicated.

• Genus and species: Rosa hybrida.
• Varietal denomination: ‘NOA250092’.
• Parentage:
  • • Seed parent.—‘NOACK ROSEN Seedling’ (unpatented in the United States).
    • Pollen patent.—‘NOACK ROSEN Blühendes Barock’ (variety: NOAbell) (unpatented in the United States).

The new rose plant can be distinguished from its parents by its flowers. The seed parent has single flowers, with 5 to 8 petals. The new rose variety has semi-double flowers, with about 16 soft pink petals, which contrast attractively with the bright orange stamens. The pollen parent has medium pink, double flowers. In addition, the pollen parent has a small and compact growth habit. No similar cultivars are known.

• Class: Shrub.

The following observations were made on one and half-year-old budded specimens grown outdoors in Gütersloh, Germany, during the month of July 2002.
