USPP8596P - Floribunda rose plant named `JACdaz` - Google Patents

Abstract

A floribunda rose having disease resistant dark green leathery foliage, bright red flowers, profusion of blooms, and being easily propagated by softwood or hardwood cuttings or by budding.

Description

The 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 Razzle Dazzle, U.S. Plant Pat. No. 3,995, with an unnamed rose pink seedling.

The primary objective of this breeding was to produce a new rose variety having the bright red flower color and dark green leathery foliage of Razzle Dazzle combined with the heavy flower production and mildew resistant foliage of the rose pink floribunda unnamed seedling. The 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. Bright red flower color;

2. Resistance to powdery mildew and rust;

3. Propogates easily from softwood or hardwood cuttings and by budding;

4. Has dark green leathery glossy foliage;

5. Heavy and continuous bloom production.

Asexual reproduction of this new variety by budding and by softwood and hardwood cuttings, 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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
