Rose plant 75-20031 jacdew

Abstract

A floribunda rose variety having a bush which blooms continuously through the growing season; glossy foliage; orange-red blooms which fade to lighter color before falling; little or no fragrance; numerous prickles.

Description

This present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety America, U.S. Plant Pat. No. 3,682, with an unnamed variety.

The primary objective of this breeding was to produce a new rose variety of the floribunda class with abundant blooms and disease resistant foliage. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. A floribunda type bush, blooming continuously through the growing season.

2. Foliage glossy and nearly immune to rose powdery mildew.

3. Blooms of orange-red fading to a lighter color before falling.

4. Very little or no fragrance.

5. Numerous large and small prickles.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, 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 in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.
