USPP36660P2 - Floribunda rose plant named ‘Spropuff’ - Google Patents

Abstract

A new and distinct variety of floribunda rose plant, referred to by its cultivar name, ‘Spropuff’, is described. The new variety forms in abundance on a substantially continuous basis medium pink colored blossoms. The growth habit is very bushy and upright to rounded. Glossy foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘Spropuff’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was December 2022. The first offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. The first offer for sale was by Star® Roses and Plants. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of floribunda rose plant of the present invention was created by controlled breeding in April 2016, in Bakersfield, California 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) of the new variety was an unnamed breeder seedling (not patented), which was the product of the cross of a different unnamed seedling and ‘WEKvossutono’ (U.S. Plant Pat. No. 18,473; Julia Child™), wherein the different unnamed seedling was a product of the cross of ‘Meimonblan’ (U.S. Plant Pat. No. 12,579; Marmalade Skies™) and ‘Baby Love’ (not patented). The male parent (i.e., the pollen parent) of the new variety was the ‘Sprogreatpink’ variety (U.S. Plant Pat. No. 32,663).

The parentage of the new variety can be summarized as follows:
([‘Meimonblan’ x ‘Baby Love’] x ‘WEKvossutono’) x ‘Sprogreatpink’

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.

The new variety has been found to undergo asexual propagation at Wasco, California and Cochranville, Pennsylvania by a number of routes such as vegetative cuttings. Asexual propagation techniques in Wasco, California and Cochranville, Pennsylvania such as vegetative cuttings, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of floribunda rose plant of the present invention possesses the following combination of characteristics:

• • (a) forms medium pink colored blossoms,
  • (b) exhibits a very bushy and upright to rounded growth habit, and
  • (c) provides glossy, dark green colored foliage.

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 residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the unnamed breeding seedling female parent (i.e., the seed parent) produces flowers with less petals compared to the medium pink colored flowers of the new variety. Additionally, the new variety produces a higher petal count and a more upright growth habit compared to the ‘Sprogreatpink’ variety (i.e., the pollen parent). Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, ‘Radshining’ (U.S. Plant Pat. No. 28,993) displays less petals and deep pink colored flowers compared to the medium pink colored flowers of the new variety.

The new variety has been named the ‘Spropuff’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 new variety and blossoms of the new variety. The illustrated rose plant of the new variety was photographed in April 2022, and was approximately two years of age and was grown outdoors in a field on its own roots in Arroyo Grande, California.

Drawing illustrates a specimen of the plant displaying flowers at varying points of opening.
