WHITE ROSE PLANT Filed Feb. '7, 1972 United States Patent O 3,402 WHITE ROSE PLANT Robert G. Jelly, Richmond, Iud., assignor to E. G. Hill Co. Inc., Richmond, Va. Filed Feb. 7, 1972, Ser. No. 224,349 Int. Cl. Alh 5/00 US. Cl. Plt.--23 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of rose plant bred for greenhouse production of cut flowers and distinguished by its abundant and continuous production of an almost pure white flower of excellent form, borne on medium to long moderately strong stems, and having a relatively long vase life at living room temperatures.

BACKGROUND OF THE INVENTION The hereindescribed new variety of rose plant was developed by me at Richmond, Ind., with the object of producing an improved white flower having better form and color characteristics and a plant having a vigorous and free growth habit for the continuous production of the blooms to be marketed as cut flowers. This new plant originated as a seedling produced by crossing Jack Frost (RP. 2,447) with Seventeen (P.P. 1,765) in January 1964 and with the blooming of the first flower in August 1964, it was evident that my objectives had been satisfactorily realized.

Asexual propagation of this new plant through succeeding generations by grafting at Richmond, Ind., and by budding at Livermore, Calif., has demonstrated that its distinguishing characteristics hold true from generation to generation and are firmly fixed.

DESCRIPTION OF THE DRAWING My new variety of rose plant is illustrated by the accompanying drawing which shows the color characteristics of the new plant as nearly true as it is reasonably possible to obtain by conventional photographic procedures and which shows typical specimens of the bud in various stages of opening, a face view of the fully opened flower, specimens of typical leaves showing the venation of the leaflets, and specimens of young and mature wood.

DESCRIPTION OF THE NEW PLANT The following is a detailed description of the new variety of rose plant as observed in greenhouse at Richmond, Ind., with color designations according to the R.H.S. Colour Chart of The Royal Horticultural Society, Nickersons Color Fan, and Wilsons Hortcultural Colour Chart as published by The Royal Horticultural Society, identified herein as (R), (N), and (W), respectively.

Foliaceous appendages on bud surface with parts extending beyond the tip a distance equal to Mr or more of the bud length. Color: Shaded from Pod Green 061 (W) at base to Yellow Green 146B (R) to a slight shade of red at the'top of the foliaceous appendage. As calyx breaks, the form and outside color remain the same. a

Color: As first petal opens-color of petals. Outside: White 155B (R) to Yellow Green 150C (R) to 150D (R) at the base. Inside: White A (R) to Yellow Green 150C (R) to Yellow Green 150D (R) at the base.

Size: When fully openedMedium, 2 /2 to 3 /2 inches in diameter.

Form: High centered at first with petals rolled outward becoming flat to globular with petals remaining rolled outward.

Coley-May be modified by being shaded with other co ors.

The following is the color description, made in April 1971, of a newly opened flower taken from a greenhouse rose grown at Richmond, Ind.:

Outside petal.-Outer and inner surfacesshaded from Yellow-Green 145C (R) at the base to White 1553 (R).

Intermediate petaL-Same as outside petal.

Inner petal.--Outer and inner surfaces-shaded from Yellow-Green 145C (R) at the base to Green- White 157D (R).

The following color description is from a greenhouse rose grown at Richmond, Indiana, and opened for three days in April 1971:

Outside, intermediate and inner petals.uter surfaces'--shaded from Yellow-Green 145C (R) at the base to White 155B (R). Inner surfacesshaded from Yellow-Green 145C (R) at the base to White 155B (R).

General color effect: The newly opened flower is mainly an overall White 155D (R) with a very light Aureolin 3/3 (W) cast at the center of the blossom. As the blossom matures, the color appears to darken slightly, as in a three days opened flower which has a general coloring slightly lighter than White 155A (R).

Hips.-None available.

My new variety of rose plant is an improvement over the seed parent, Jack Frost (P.P. 2,447), in that it has a more pointed and attractive bud, a longer stem and its blossoms are of a whiter color. The new plant is also a material improvement over its pollen parent, Seventeen (P.P. 1,765), because it has a more vigorous growth, its blossoms have a better and more pleasing texture and, as a cut flower, it has a longer lasting vase life under ordinary living room temperatures. The combination of these advantageous factors provides a new and improved rose plant of real commercial value as a strong producer of an almost pure white flower particularly suitable for the cut flower market.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by the very white color of its blossoms, its continuous and abundant production of flowers on strong stems of medium length, and its vigorous growth under greenhouse culture.
