Abstract

A new and distinct variety of hybrid tea rose produced by me crossing First Prize (U.S. Plant Pat. No. 2,774) with Piccadilly (not patented in the United States, but grown widely in Europe).

Description

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by crossing First Prize (U.S. Plant Pat. No. 2,774) with Piccadilly (not patented in the United States, but hybridized by Samuel McGredy in Ireland and grown widely in Europe). The new and distinct variety was asexually reproduced by budding in Warren, Mich., the seedling was taken to Shreveport, La. 71105, where it was further asexually reproduced by budding and observed.

This rose differs from its seed parent First Prize by having a bush that produces more basal canes with smaller foliage and more thorns, with blooms that usually come one to a stem, have a shorter bud, more petals, and are a different color.

This rose differs from its pollen parent Piccadilly by having a plant with matte rather than glossy foliage and more thorns, with blooms that have more and thicker petals to give better form and substance, and are a different color.

The accompanying drawing shows typical specimens of the growth and habit of my new variety in different stages of development in October 1978 in Shreveport, La., the color as nearly true as it is possible to make the same in a color illustration of this character. The colors in the following description are taken from the color chart of the Royal Horticultural Society, where a color designation number is shown. The other color designations are ordinary dictionary terms, where no color number is assigned.

The following is a detailed description of my new rose variety:

Type: Upright bush, seedling, for garden decoration.

Class: Hybrid tea.
