ABSTRACT:
BOTANICAL/COMMERCIAL CLASSIFICATION
Rosa hybrida
/Ground Cover Rose Plant.
VARIETAL DENOMINATION
cv. Noalesa.
SUMMARY OF THE INVENTION
Ground Cover rose plants are known and are being used to advantage in an increasing number of landscape plans and home gardens. However, there remains a need for additional varieties of Ground Cover roses with the demand being the greatest for those having highly attractive blossoms in combination with good disease resistance.
The new variety of
Rosa hybrida
Ground Cover rose plant of the present invention was created at Gütersloh, Germany, 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) was the ‘Korimro’ variety (non-patented in the United States). Such ‘Korimro’ variety possesses light pink to near white single blossoms and is marketed under the IMMENSEE trademark. The male parent (i.e., the pollen parent) was an unnamed seedling maintained by Noack Rosen at Gütersloh, Germany (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Korimro’×Unnamed Seedling.
The seeds resulting from the above pollination were sown and small plants were obtained which physically and biologically differ from each other. Selective study resulted in the identification of a single plant to the new variety.
It is found that the new variety of Ground Cover rose plant possesses the following combination of characteristics:
(a) Forms attractive bright yellow blossoms,
(b) Young plants exhibit an upright growth habit that becomes spreading, dense, and compact with maturity,
(c) Forms attractive dark green glossy foliage that contrasts well with the bright yellow blossoms,
(d) Exhibits excellent disease resistance with respect to Blackspot, Powdery Mildew, and Rust, and
(e) Is particularly well suited for growing as attractive ornamentation in the landscape.
The new variety meets the needs of the horticultural industry and can be grown to advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes.
The new variety of the present invention beginning in 1994 has been asexually reproduced by the rooting of cuttings, by budding, and by grafting. Such asexual reproduction as performed at Gütersloh, Germany, has demonstrated that the characteristics of the new variety are firmly fixed and stable and are strictly transmissible from one generation to another.
The new variety has been named the ‘Noalesa’, and recently has been marketed abroad under the JACOBS KRÖNUNG trademark.
