Hybrid tea rose plant named Hilrap

Abstract

A new variety of hybrid tea rose having rich velvety red flowers produced on a plant suitable for greenhouse growing.

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 the seed and pollen parents two unnamed and unpatented seedlings of my creation. The varietal denomination of this new rose is `Hilrap`.

Among the novel characteristics possessed by this new variety which distinguishes it from all other varieties of which I am aware are its attractive rich velvety red flowers with excellent imbrication. As a partially opened cut flower `Hilrap` is urn shaped with an attractive elongated bud. The flowers are large and are borne singly in a manner typical of hybrid tea varieties.

Asexual reproduction by grafting of the new variety as performed in Richmond, Ind. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. The new variety can be asexually propagated by budding, grafting, propagation from cuttings and by micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustrations show 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 different climate, soil, and cultivation conditions.

One of the illustrations shows plant parts, including compound five and seven leaflets, a stem, new growth, buds after sepals part and after sepals fall, a bloom 1/3 open and a bloom fully open. The other illustration depicts typical form and configuration of flower and bud as cut flowers.

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.
