Abstract:
A new and distinct variety of Climbing rose plant is provided which abundantly forms attractive yellow blossoms having a slight fragrance and the configuration of an old rose. The plant displays good vigor and good tolerance to diseases, particularly with respect to Black Spot. The foliage is very dense and semi-glossy, and contrasts nicely with the blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in the landscape where a climping rose plant is desired.

Description:
Botanical/commercial classification:  Rosa hybrida /Climbing Rose. 
   Varietal denomination: cv. Meivanery. 
   SUMMARY OF THE INVENTION 
   The new variety of  Rosa hybrida  Climbing rose plant was discovered during June 1999, at Le Cannet des Maures, Var, France, while growing among plants of the ‘Meitosier’ variety (U.S. Plant Pat. No. 9,233). The new variety was found to display a distinctive blossom coloration unlike that of the ‘Meitosier’ variety, and is believed to be a spontaneous mutation of unknown causation of such variety. The blossoms of the new variety exhibit an attractive yellow coloration unlike the light Mandarin Orange blossom coloration of the ‘Meitosier’ variety. Had the new variety of the present invention not been discovered and preserved, it would have been lost to mankind. 
   It was found that the new rose variety of the present invention:
         (a) exhibits a climbing growth habit,   (b) abundantly forms on a substantially continuous basis attractive yellow blossoms having a slight fragrance and the configuration of an old rose,   (c) forms very dense semi-glossy foliage that contrasts well with the blossom coloration,   (d) displays good vigor,   (e) displays good disease tolerance, particularly with respect to Black Spot, and   (f) is particularly well suited for growing as attractive ornamentation in the landscape.       

   The new variety well meets the needs of the horticultural industry and can be used to advantage for growing in the landscape where an attractive climbing rose plant is desired. 
   The new variety of the present invention can be readily distinguished from its ‘Meitosier’ parent variety through a comparison of the blossom colorations that are displayed. 
   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. 
   The new variety has been named the ‘Meivanery’ 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, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately one year of age and were observed during July while budded on  Rosa froebelii  understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters and a standard color presentation are indicated at the bottom of the photograph.

   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 one-year-old plants during July while budded on  Rosa froebelii  understock and growing outdoors at Le Cannet des Maures, Var, France.

Thorns. —Size: variable (as illustrated), with the longest thorns commonly being approximately 10 mm in length. Quantity: an adult stem having a length of 10 cm commonly will bear approximately 4 smaller thorns having lengths of approximately 8 mm on average, and an adult stem having a length of approximately 15 cm commonly will bear approximately 7 longer thorns having a length of approximately 10 mm on average. Configuration: rather straight longish-pointed on upper surface and slightly concave on the under surface (as illustrated).
