Miniature rose plant named `Savanight`

Abstract

A new miniature rose plant variety with many petalled, fragrant pink flowers.

Description

BACKGROUND 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 crossing as seed parent the hybrid tea variety known as `Taxi` and as pollen parent the variety known as `Benalav` (U.S. Plant Pat. No. 6,517). The varietal denomination of this new rose is `Savanight`.

SUMMARY OF THE INVENTION

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 large, many petalled attractive fragrant pink flowers.

Asexual reproduction by propagation of vegetative 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

Among other respects, the new variety differs from its parents in flower color. `Taxi` produces red flowers and `Benalav` flowers are mauve.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the flowers of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

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 (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with light availability, environmental and cultural conditions.

Parentage:

Seed parent.--`Taxi`.

Pollen parent.--`Benalav`.

Class: Miniature.

The following observations are made of specimens grown under plastic in Essex County, Mass. during October.

FLOWER

Blooming habit: Recurrent.

A. Bud:

(1) Size.--Medium.

(2) Form.--Obtuse with acute tip.

(3) Color.--When sepals first divide, bud color is between 49C and 49B.

(4) Sepals.--Slightly bearded; only slightly longer than bud; near 144A; sepals roll back quickly when a bud starts to open and usually remain at about 45.degree. angle from the peduncle until bloom is fully open then roll back to, and occasionally crossing over the peduncle as blooms age; remain attached.

(5) Peduncle.--Length--about 11/4 to 11/2 inches. Aspect--straight. Strength--bends with weight of open bloom. Color--near 146B.

B. Bloom:

(1) Size.--Average size when fully expanded up to about 21/8 inches.

(2) Borne.--Mostly singly; sometimes in clusters of 2 to 5 to a stem.

(3) Form.--Opens flat; petals loosely roll outward.

(4) Petalage.--Number of petals under normal conditions about 52 to 62.

(5) Color.--Inner petals at center of flower near 55B, reverse near 55C; outer petals near 55C, reverse near 55C; when half-blown inner petals near 55C, reverse near 55C; outer petals near 55C, reverse near 49C; base of petals near 154D; general tonality from a distance medium pink.

(6) Color change.--As bloom ages, color changes from near 49C to near 55C to 55B and 55C; then to near 55C and 55D; after three or more days general tonality is medium pink.

C. Petals:

(1) Texture.--Medium.

(2) Appearance.--Outside satiny, inside satiny.

(3) Form.--Outer petals nearly round, graduating to oval inner petals with acute apex.

(4) Arrangement.--Irregularly arranged; overlapping, sometimes almost doubling up.

(5) Petaloids in center.--About 40 often with streak of white or near 154D.

(6) Persistence.--Drop off cleanly in 5 to 8 days.

(7) Fragrance.--Very strong.

(8) Lasting quality.--About 5 to 8 days on the plant; about 4 to 7 days as a cut flower.
