Hybrid tea rose plant named Devfrago

Abstract

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

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 and pollen parents two unnamed and unpatented seedlings of our creation. The varietal denomination of this new rose is `Devfrago`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware is its attractive apricot flower coloration.

Asexual reproduction by propagation 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.

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 illustrations of this character. Phenotypic expression, including colors, may vary depending upon growing conditions, such as climate, soil, and cultivation conditions.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a 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 the color descriptions herein refers to plate numbers in the aforementioned color chart.

Parentage: Seedling.

Seed parent.--Unnamed seedling.

Pollen parent.--Unnamed seedling.

Class: Hybrid Tea.

The following further horticultural observations were made of specimens grown in greenhouses in Watsonville, Calif. in the months of January and February.

FLOWER

Blooming habit: Recurrent.

A. Bud:

(1) Size.--Small.

(2) Form.--Slender -- tapering.

(3) Color.--As sepals first divide, near 31C to 40C with some reddish flush; base of petal near 22A.
