Rose plant named `Verolwek`

Abstract

A new hybrid tea rose variety with relatively large blooms of yellow coloring.

Description

SUMMARY OF THE INVENTION

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 an unnamed, unpatented rose of my creation and as pollen parent the rose known as "Yellow Yo Yo". The varietal denomination of this new rose is "Verolwek".

Among the novel characteristics possessed by this new variety which distinguishes it from its parent and all other varieties of which I am aware are its attractive relatively large yellow flowers of good form that maintain their color through development and aging.

The new variety, "Verolwek", produces full, vigorous, heavily foliaged plants and masses of medium to deep yellow, large blooms. The flowers are somewhat informal in form as compared to the classic exhibition rose. However, the petals are large and maintain good substance through aging. The flowers hold well upon opening and their disciplined form is one of the charms of this new rose cultivar.

"Celebrity" is a dual purpose variety. The robust plant with full beautiful foliage covered recurrently with masses of large distinctive yellow flowers is useful as a desirable landscape rose and also produces an abundance of long stem flowers useful for cutting.

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.

BRIEF DESCRIPTION OF DRAWING

The accompanying drawing shows typical specimens of the vegetative 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.

HORTICULTURAL DESCRIPTION OF THE NEW VARIETY

The following is detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "151C" is plate 151C of The Royal Horticultural Society Colour Chart.
