ABSTRACT:
Botanical/commercial classification: Rosa hybrida/Grandiflora Rose Plant.
Varietal denomination: cv. ‘Wezlavn’.
SUMMARY OF THE INVENTION
The new variety of
Rosa hybrida
Grandiflora rose plant was created 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 the ‘Sterling Silver’ variety (U.S. Plant Pat. No. 1,433). The male parent (i e., the pollen parent) was the ‘Silver Spoon’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Sterling Silver’בSilver Spoon’.
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.
It was found that the new variety of Grandiflora rose plant of the present invention possesses the following combination of characteristics:
(a) exhibits a bushy and well balanced growth habit,
(b) forms attractive double blossoms that are light to medium lavender in coloration,
(c) forms medium green semi-glossy foliage,
(d) exhibits good disease resistance, and
(e) is particularly well suited for growing as attractive ornamentation.
The new variety well meets the needs of the horticultural industry and can be grown to advantage for cut flower production, as a specimen plant, or in a mass planting.
The new variety of the present invention can be readily distinguished from its ancestors. More specifically, the new variety is Grandiflora rose plant that forms medium to light lavender blossoms having approximately 30 petals on average and no fragrance. The ‘Sterling Silver’ variety is a Hybrid Tea that forms lilac-colored blossoms having an intense citrus/fruity fragrance. The ‘Silver Spoon’ variety also is a Hybrid Tea and forms blossoms of a mauve blend having approximately 35 petals on average.
The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques at Wasco, Calif. 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 ‘Wezlavn’ variety. The new variety is being marketed under the SILVER STAR trademark.
