Hybrid tea rose plant named ‘Femme Fatale’

Abstract

A new and distinct variety of shrub rose plant, herein referred to by its cultivar name, ‘Femme Fatale’, is provided which abundantly, and continuously forms deep pink colored blooms. The growth habit is upright and sturdy. The foliage is dark green in color with a rough texture. The plant propagates from cuttings easily and uniformly. The blossoms are exceptionally fragrant, and exceptionally heat tolerant. The new variety is well suited to growing in warm climates, and as a source of attractive ornamentation and fragrance in in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Varietal denomination: ‘Femme Fatale’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created at Brenham, Tex., U.S.A., by artificial pollination wherein two parents were crossed which previously had been observed in the hope that each would contribute their desired traits. The female parent (i.e., the seed parent) was a non-patented seedling variety named ‘Komodo’. ‘Komodo’ is derived from the varieties ‘Proud Land’ (U.S. Plant Pat. No. 2,737) and ‘Radbrite’ (U.S. Plant Pat. No. 17,391). The male parent (i.e., the pollen parent) was the ‘TEXpeaswi’ variety (non-patented). The parentage of the new variety can be summarized as follows:
‘Komodo’ x ‘TEXpeaswi’

The seeds resulting from the above pollination were stratified in an artificial environment and sown into trays in a greenhouse environment. Seedlings were obtained and displayed phenotypic and biological variation. Selective trialing and evaluation of the seedlings resulted in the identification of a single plant of the new variety.

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

• • (a) abundantly, and continuously forms deep pink colored blooms,
  • (b) exhibits an upright and sturdy growth habit,
  • (c) exhibits exceptionally fragrant blooms,
  • (d) forms disease resistant foliage that is dark green in color and rough in texture,
  • (e) exhibits exceptional heat tolerance, and
  • (f) is well suited for growing in warm climates, and as a source of attractive ornamentation and fragrance in in the landscape.

The new rose can be readily distinguished from its ancestors upon inspecting the blossoms. More specifically, the ‘Femme Fatale’ variety forms blossoms which are deep pink in coloration, while the parental variety ‘TEXpeaswi’ forms dissimilar blossoms which are striped, apricot and pink in color. The new variety can also be readily distinguished from its ancestors upon observing the fragrance of the blossoms. ‘Femme Fatale’ produces blossoms with an exceptionally strong damask fragrance, while the parental varieties ‘Komodo’ and ‘TEXpeaswi’ produce blossoms which are mild in fragrance.

The new variety of the present invention also can be readily distinguished from other hybrid tea rose plants, including the ‘Miss All-American Beauty’ variety (U.S. Plant Pat. No. 2,625) upon observation of the disease resistance of the foliage. For example, the ‘Miss All-American Beauty’ variety forms foliage which is susceptible to black spot Diplocarpon rosae, which is dissimilar to the foliage of ‘Femme Fatale’ which is resistant to black spot Diplocarpon rosae.

Asexual reproduction of ‘Femme Fatale’ was done by taking cuttings in Brenham Tex., U.S.A. in beginning in 2019. Cuttings were taken from mature stems that were approximately 10 to 15 cm in length and approximately 0.75 cm in diameter. Initial cuttings were taken of the new variety and grew into mature plants. Subsequent cuttings were taken of the initial asexually reproduced plants and grown into mature plants. Mature plants of both the initially propagated plants and the subsequently propagated plants were compared. There was no observable difference between the generations. Therefore, it was demonstrated that the characteristics of ‘Femme Fatale’ remain stable, uniform, and true to type in successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true is as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the plant parts, i.e., the flowers, buds, stems and leaves of the new rose, ‘Femme Fatale’. The illustrated rose plant parts were approximately one year of age and were observed during August, while growing on their own roots in Brenham, Tex., U.S.A. Flowers, buds, and stem growth are displayed in various stages of maturity. The upper side and under side of the leaves, blooms and petals are displayed.
