Grandiflora rose plant variety named `Twocherish`

Abstract

A grandiflora rose variety producing coral red flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct shrub rose variety which was originated by my crossing as seed parent an unnamed and undistributed seedling and as pollen parent the variety known as `Silver Jubilee`. The new variety differs from `Silver Jubilee` in growth habit and flower color. The flower of `Silver Jubilee` are a pink blend with apricot and cream whereas the flower color of the new variety is coral red.

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 coral flowers borne on a bushy, vigorous plant. The varietal denomination of the new variety is `Twocherish`.

Asexual reproduction by budding of the new variety 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. Other known forms of asexual reproduction may be also employed.

BRIEF DESCRIPTION OF ILLUSTRATION

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: Seedling.

Seed parent.--Unnamed, undistributed, and unpatented seedling.

Pollen parent.--"Silver Jubilee".

The following is a detailed description of the new variety, from specimens grown outdoors in Watsonville, Calif., in the month of September. The color terminology used is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), and refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending on light, environmental and cultural conditions.
