Hybrid tea rose plant named `Morjoybon`

Abstract

A new variety of hybrid tea rose plant producing apricot blend flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose of the hybrid tea rose class which was originated by my crossing as seed parent the variety known as `Morjoye` (U.S. Plant No. 7,055) and as pollen parent the variety known as `Bon Silene.` The varietal denomination of this new rose is `Morjoybon.`

Among the novel characteristics possessed by this new variety which distinguishes it from its parents are its floriferousness and apricot blend flowers. The plant grows and blooms well both in the greenhouse and outdoors and is good for garden decoration. Plants of the new variety are vigorous and have a rounded to upright growth shape. Garden plants flower throughout growing season.

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

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression of the variety herein described, including colors, may vary depending upon growing conditions, such as climate, soil, and environmental conditions.

DESCRIPTION OF THE NEW VARIETY

The terminology used in color description herein refers to plate numbers in the aforementioned color chart. General terms such as average, normal, ordinary, medium, etc. are used in their normal sense and the characteristics so described are not considered distinguishing.
