Floribunda rose plant named Tworight

Abstract

A new floribunda rose plant producing bright red flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the floribunda rose class which was originated by my crossing as seed parent an unnamed and unpatented seedling of my creation and as pollen parent the variety known as `Evening Star` (U.S. Plant Pat. No. 3,432). The varietal denomination of this new rose is `Tworight`.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive, bright red flowers borne on a plant resistant to mildew and blackspot.

Asexual reproduction by budding as performed in Watsonville, Calif. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

Parentage:

Seed parent.--Seedling.

Pollen parent.--`Evening Star`.

Class: Floribunda.

The following is a detailed description of specimens of the new variety, grown outdoors in Watsonville, Calif. in September with color terminology in accordance with the Royal Horticultural Society Colour Chart (RHSCC). The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with environmental and cultural conditions.
