Rose plant
1. A new and distinct cultivar of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a bushy, heavily branched plant, high greenhouse production of buds of a clear Buttercup Yellow (W), whose shape is oval but with a blunt or flat tip; Spinach Green (W) glossy foliage and a strong fragrance.

This invention relates to a new and distinct cultivar of rose plant of the floribunda class, originated by me by crossing the cultivar Mabella, with pollen from the cultivar Minigold.
The primary objective of this breeding was to produce a new and improved cultivar of the floribunda class bearing pure, clear yellow buds and blooms on plants especially suitable for production of cut flowers in greenhouses.
This objective was fully achieved along with other desirable traits as evidenced by the following unique combination of characteristics which are outstanding in the new cultivar and which distinguish it from its parents as well as from all other cultivars of which I am aware:
1. A bushy, compact plant, making numerous new branches, or canes, from the base of the plant.
2. A habit of growth similar to the cultivar Mercedes, U.S. Plant Pat. No. 3,724.
3. A long, oval bud form with a blunt or flat tip.
4. Very, stiff petals which are near Buttercup Yellow.
5. A high centered open flower of approximately 35-40 flowers.
6. A strong, pleasant fragrance.
7. Glossy, Spinach Green foliage.
Asexual reproduction of this new cultivar by budding as performed at Elmshorn, Holstein, W. Germany and near Irvine, Calif., shows that the aforementioned characteristics come true to form, and are established and are transmitted through succeeding propagations.
The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
The following is a detailed description of my new rose cultivar, with color terminology in accordance with Wilson's Horticultural Color Chart, except where ordinary meanings are applicable:
