Floribunda rose plant named `JACsur`

Abstract

A floribunda rose plant characterized by the unique combination of its excellent display of well-shaped flowers borne both as single flowers and in clusters, its dark green, glossy, disease-resistant foliage, its vigorous growth and its good plant habit.

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 JACjem, U.S. Plant Pat. No. 5,001, with the variety JACdew, U.S. Plant Pat. No. 5,122.

The primary objective of this breeding was to produce a new rose variety having the excellent floribunda habit, flower production, disease resistance, and glossy foliage of JACjem combined with the higher petal count, better formed flowers, and very vigorous growth of JACdew. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Dark green, glossy, disease-resistant foliage;

2. Well-formed flowers;

3. Excellent floribunda habit;

4. Profuse flower production, usually in clusters of 3 to 5; and

5. Vigorous growth.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other 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.
