Rose plant

Abstract

A new hybrid tea rose variety of substantially nonfading bright red coloring.

Description

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent the rose known as "Christian Dior" and the rose known as "Mr. Lincoln" as pollen parent.

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 brilliant red, substantially non-fading, non-bluing, singly borne blooms, developing from long buds and a vigorous, free branching plant with abundant foliage dense to ground level and outstanding disease resistance. Blooms are very long lasting on the plant and as cut flowers. Asexual reproduction by budding of the new variety as performed in Kern County, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The new and improved rose variety which I have developed is an unusually fine hybrid tea rose of strong red coloring which holds well and has outstanding substance displayed on a vigorous, free branching plant with abundant disease resistant foliage. The flowers are of heavy petalage but open well and have a good old rose fragrance.

The accompanying drawing shows typical specimens of the vegatative growth and flowers of the new variety 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 variety, with color terminology in accordance with the Royal Horticultural Society Color Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "42B" is plate 42B of the Royal Horticultural Society Color Chart.

Color.--28B.

Do seeds protrude.--No.

PLANT

A. Form: Upright.

B. Growth: Very vigorous, uniform branching, many canes break from bud union.

Height attained.--About 5 feet.

C. Foliage: Compound 5 to 7 leaflets.

(1) Size.--Large.

(2) Quantity.--Abundant, dense to ground level.

(3) Color.--New foliage: Upper side -- near to 147A with purplish veining. Under side -- near to 147C with purplish tonality. Old foliage: Upper side -- near but darker than 137A. Under side -- near 138B.

(4) Shape.--Oval.

(5) Texture.--Upper side is leathery and under side is dull.

(6) Edge.--Serrated.

(1) New wood.--Color -- near 137D with reddish cast. Bark -- smooth.

(2) Old wood.--Color -- near 138A on upper growth and 146A on lower parts of plant. Bark -- smooth.

E. Thorns:

Claims

1. A new and distinct variety of rose plant of the hybrid tea class, substantially as shown and described, characterized particularly by large brilliant red flowers which hold color well upon aging, are borne primarily singly to a stem and are long lasting on the plant and as cut flowers.
