Climbing miniature rose plant named `Chewizz`

Abstract

A new and almost continuously and profusely blooming rose plant, of the climbing miniature class, having conspicuous, open-faced flowers with petals gently rounded shape but having a minute point on the centerline; such petals of brilliant orange with yellow at their base; the flowers being pleasantly highlighted by their placement over a healthy and dense crop of rich red-toned new foliage and glossy green mature foliage on a tall upright vigorously growing, well branched plant.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the climbing miniature rose class which was originated by me by crossing, as the seed parent, `Irish Beauty`.times.(Galway Bay.times.Sutter's Gold (U.S. Plant Pat. No. 885)) seedling and as pollen parent the rose plant known as `Anna Ford`. Upon recognition of the attributes of this plant within the progeny of the stated cross, it was elected for further testing and observation. Upon recognition that this plant was novel and expressed numerous superior and desirable traits as described below, the plant of this application was assigned an international recognition name of `Chewizz`. This plant has been asexually reproduced by me or under my direction by cuttings and by budding in Washington County, Oreg. Such asexual reproduction has conclusively shown that all distinguishing characteristics of this plant come true to form, are firmly fixed, and are faithfully transmitted through succeeding propagations.

Specimens described below were grown in Washington County, Oreg.

SUMMARY OF THE INVENTION

The new plant of this invention contains a number of outstanding attributes in combination which set it apart from all other plants of the miniature rose market class. Such characteristics may be summarized as follows:

A new and conspicuously attractive flower having bright orange petals.

Petals of gently rounded shape of bright orange coloring with yellow showing at base of petals, having a small point at the center of the rounded apex of the margin.

Open faced flowers which open to a substantially flat form.

Flowers being pleasantly highlighted above lush, dense foliage which is healthy in appearance.

A tall plant which is highly remontant and blooms almost continuously and profusely.

Flowers formed singly or in sprays placed over a healthy and dense crop of red-brown new foliage and deep green mature foliage of an upright compact but vigorously growing, well branched plant.

DESCRIPTION OF THE DRAWING

The submitted photographic illustration shows typical foliage and blooms of the new cultivar in various stages of maturity.
