USPP9799P - Miniature rose plant named `Savaspark` - Google Patents

Abstract

A new miniature rose with red flowers of good form.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was created by me by crossing as seed parent an undisseminated seedling of my creation and as pollen parent the variety known as `Ruimired` (U.S. Plant Pat. No. 5,770). The varietal denomination of this new rose is `Savaspark`.

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 red flowers of good form which open well and are borne on a vigorous, profusely blooming plant.

Asexual reproduction by propagation of cuttings of the new variety as performed in Essex County, Mass. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

The new variety produces red flowers larger than its pollen parent and differs from the seed parent in flower color; the seed parent providing orange red flowers.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers of the new variety in different stages of development depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression may vary with light availability, environmental and cultural 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 color description herein refers to plate numbers in the aforementioned color chart.

Parentage:

Seed parent.--Unnamed seedling.

Pollen parent.--`Ruimired`.

Color near 144A. As flower begins to open, the sepals gradually bend back but do not reach the flower stem until the petals start to fade. The sepals remain attached after the petals drop. The tips usually curl up slightly.

(2) Borne.--Usually in sprays, but sometimes singly; accompanying illustration shows one stem from the plant; profuse.

(3) Form.--High centered, remaining high centered until petals drop from the plant.

(4) Petalage.--Number of petals under normal conditions about 18-24.

(5) Color.--During first two days, inner petals at center of flower near 45B; reverse near 46C; outer petals near 46B, reverse near 45D; base of petals at point of attachment near 4C; general tonality from a distance medium red.

(6) Color change.--As bloom ages, color changes from near 45A to near 45B and near 46B, to near 45D and near 46C, to near 43A to near 47B as the petals drop; general tonality; medium red, after three or more days, medium red.

C. Petals:

(1) Texture.--Average for class.

(2) Appearance.--Inside velvety and outside satiny.

(3) Form.--Obtuse.

(4) Arrangement.--Imbricated, regularly arranged, shingle-like.

(5) Petaloids in center.--0-3; no distinguishing characteristics.

(6) Persistence.--About 8-12 days.

(7) Fragrance.--None.

(8) Lasting quality.--About 8-12 days on the plant; about 8-15 days as a cut flower, depending on conditions.
