Rose plant-charisma variety

Abstract

A rose plant of the Floribunda class originated by crossing Gemini (U.S. Plant Pat. No. 2,728) with Zorina (U.S. Plant Pat. No. 2,321).

Description

SUMMARY OF THE INVENTION

My invention relates to a new and distinct variety of rose plant of the Floribunda class originated by me in 1968 as a result of a breeding program using Gemini (U.S. Plant Pat. No. 2,728) as pollen parent and Zorina (U.S. Plant Pat. No. 2,321) as seed parent.

The objective of this breeding program was to combine the strong vivid coloring of both parents, along with the superb blooming qualities and the superb dark green foliage. I was successful in achieving this objective. As a result of this crossing, I have produced a new and useful rose variety which is distinguished from its parents, and all rose varieties of which I am aware, as evidenced by the following unique combination of characteristics:

1. A plant of compact and freely branched growth.

2. A plant habit of even regular form having a neat well balanced appearance, with very attractive distinctive foliage.

3. A floriferous plant producing good quantities of flowers in clusters on the stem.

4. Flowers of substantially uniform size.

5. Flowers having a distinctive combination of flame red and yellow colors.

Asexual reproduction of my new variety by budding as performed at Richmond, Ind. and West Grove, Pa. shows that all characteristics of the variety are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development as depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character.

This description of a newly opened flower was made from a rose grown outdoors in July, 1975 at West Grove, Pa. 19390.

Color.--Outer petal: Outside surface -- 12A at the point of attachment, approximately two thirds of the way up the petal blending to 30C, darkening to 33A at the petal margin. Inside surface -- 146D at the point of attachment, becoming 13C two thirds of the way up the petal, becoming 33B and finally 33A at the petal margin. Intermediate petal: Outside surface -- 12 A at the point of attachment, becoming 12B 3/4 the way up the petal, becoming 32C and 32B at the petal margin. Inside surface -- 12A at the point of attachment, becoming 33B two thirds of the way up the petal and 33B at the petal margin. Inner petal: Outside surface-- 12A at the point of attachment, becoming 33C two thirds of the way up the petal, darkening to 33A at the petal margin. Inside surface -- 12A at the point of attachment, becoming 33C half the way up the petal, and darkening to 33B at the petal margin.

This description was made from a rose that was open for three days, outdoors in July, 1975 at West Grove, Pa. 19390.

Color.--Outer petal: Outside surface -- At the point of attachment 7A, 30C at the center of the petal, becoming 33A at the petal margin. Inside surface -- 2B at the point attachment, becoming 12A at the center of the petal becoming 33A at the petal margin. Inner petal: Outside surface -- 12A at the point of attachment, becoming 32B, and darkening to 32A at the petal margin. Inside surface -- 9A at the point of attachment, becoming 9B half way up the petal, becoming 32A at the petal margin.

General color effect.--Newly opened flower: 33A on the outer petals, blending with yellow to 13C at the center of the bloom. Three days open: 33A at the outer petals blending to 12A at the center of the bloom.
