Hybrid tea rose plant named ‘Meivility’

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms on a continuous basis attractive very double long-lasting cream white blossoms having a strong fragrance that are slightly suffused and bordered with pink. The new variety of the present invention is a spontaneous mutation of unknown causation of the ‘Meivildo’ variety (U.S. Plant Pat. No. 6,895). The plant exhibits very vigorous vegetation, a semi-erect growth habit, dense medium green foliage with a semi-glossy aspect, and good tolerance to crytogamic diseases such as powdery mildew. The attractive medium green foliage contrasts nicely with the blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.

Varietal denomination: cv. Meivility.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was discovered as a distinctive branch mutation at Le Cannet des Maures, Var, France, during 2002 while growing in a cultivated area among plants of the ‘Meivildo’ variety (U.S. Plant Pat. No. 6,895). The ‘Meivildo’ variety is being marketed under the YVES PIAGET trademark. I was primarily attracted to the new plant of the present invention in view of its distinctive blossom coloration. The new variety of the present invention is a spontaneous mutation of the ‘Meivildo’ variety of unknown causation. Had I not discovered and preserved the new plant of the present invention it would have been lost to mankind.

It was found that the new variety of the present invention:

• • (a) exhibits a semi-erect growth habit,
  • (b) abundantly forms on a continuous basis attractive very double long-lasting cream white blossoms having a very strong fragrance that are slightly suffused and bordered with pink,
  • (c) forms vigorous and dense medium green foliage having a semi-glossy aspect that contrasts well with the blossom coloration, and
  • (d) is particularly well suited for growing as attractive ornamentation in parks and gardens.

The disease tolerance is very good with respect to crytogamic diseases such as powdery mildew.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is desired.

The new variety can be readily distinguished from its parental ‘Meivildo’ variety. More specifically, the ‘Meivildo’ variety forms dissimilarly colored near neyron pink blossoms. This coloration is readily distinguishable from the cream white slightly suffused and bordered with pink blossom coloration of the new variety of the present invention.

The new variety also can be readily distinguished from the ‘Meimagarmic’ variety (U.S. Plant Pat. No. 5,067) and the ‘Meiparnin’ variety (U.S. Plant Pat. No. 10,477). More specifically, the blossoms of the ‘Meimagarmic’ variety exhibit no fragrance unlike those of the new variety, and the ‘Meiparnin’ variety displays a significantly taller growth habit.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France 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 of the present invention reliably undergoes asexual propagation in a true to type manner.

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

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 open blossom of the new variety. The cream white blossom coloration bordered and suffused with pink is shown. The rose plant of the new variety was approximately two years of age and was observed during May while budded on Rosa indica understock and growing outdoors at Le Cannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during February while budded on Rosa indicia understock and growing outdoors at Le Cannet des Maures, Var, France.
