Floribunda rose plant named ‘Chrisgood’

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly forms double flat cup-shaped bright multi-colored blossoms. The blossoms display a distinctive random mixture of streaks and spots of red, orange, and yellow on the upper petal surfaces. The plant exhibits an upright bushy growth habit. The foliage is medium to dark green and semi-glossy and contrasts nicely with the multi-colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in an informal garden setting.

Description

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: ‘Chrisgood’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Aromiclea’ variety (U.S. Plant Pat. No. 6,121). The ‘Aromiclea’ variety is marketed under the VODOO trademark. The male parent (i.e., the pollen parent) was the ‘JACtiger’ variety (non-patented in the United States). The ‘JACtiger’ variety sometimes is known as ‘JACtang’ and as ‘Tiger Tail’. The parentage of the new variety can be summarized as follows:

‘Aromiclea’בJACtiger’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Floribunda rose variety of the present invention exhibits the following combination of characteristics:

(a) an upright bushy growth habit,

(b) abundantly forms attractive double flat cup-shaped bright multiple-colored blossoms that are a distinctive random mixture in streaks and spots of red, orange, and yellow on the upper petal surfaces,

(c) forms medium to dark green semi-glossy foliage, and

(d) is particularly well suited for growing as ornamentation in an informal garden setting.

The disease resistance is good with respect to common rose diseases. The foliage coloration contrasts nicely that of the multi-colored blossoms.

The new variety well meets the needs of the horticultural industry and can be used to advantage for growing in the landscape where distinctive coloration is sought in a perennial or informal garden design.

The new variety of the present invention can be readily distinguished from its ancestors. For instance, both of its parents are dissimilar Hybrid Tea rose varieties. The ‘Aromiclea’ variety forms large flowers that display a blend of salmon, yellow, orange and pink. The ‘JACtiger’ variety forms flowers with deep orange, white or cream-colored stripes.

The new variety has been found to undergo asexual propagation by budding and grafting at Ontario, Calif. and West Grove, Pa. Such asexual propagation by the above-mentioned techniques has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the ‘Chrisgood’ variety.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during June 2002 and subsequently during July 2003, and September 2003 while budded on Rosa ‘Dr. Huey’ understock and growing in containers outdoors at West Grove, Pa.

Class: Floribunda.

Plant:

Height.—Approximately 65 to 75 cm on average at the end of the growing season.

Width.—Approximately 50 to 65 cm on average at the end of the growing season.

Habit.—Upright and bushy.

Branches:

Color.—Young stems: near Green Group 138A. adult wood: near Green Group 138B.

Thorns.—The thorns are variable and generally can be classified in the indicated categories with the following commonly being observed on a typical vigorous flowering stem of 15 cm length and 10 to 12 mm in diameter. Major thorns: approximately 10 to 13 (average approximately 12) in number, approximately 9.5 to 14 mm (average approximately 12 mm) in length at the base parallel to the stem axis, approximately 2.8 to 3.8 mm (approximately 3.4 mm) in width perpendicular to the stem axis, and approximately 8.5 to 10 mm (average 9 mm) in vertical height. Minor thorns: approximately 19 to 23 (average approximately 21) in number, approximately 3.8 to 7 mm (average approximately 5 mm) in length at the base parallel to the stem axis, approximately 1.15 to 2 mm (average approximately 1.4 mm) in width perpendicular to the stem axis, and approximately 3 to 6.6 mm (average approximately 5 mm) in vertical height. Minute thorns: approximately 60 to 100+ (approximately 85 on average in number, approximately 1.5 to 2.3 mm (average approximately 2 mm) in length at the base parallel to the stem axis, approximately 0.5 to 0.95 mm (approximately 0.8 mm on average) perpendicular to the stem axis, and approximately 1.5 to 2.8 mm (approximately 2.5 mm) in vertical height. Glandular hairs: relatively stiff, commonly are present on stems, petioles, rachis, petiolules, stipules, peduncles, receptacles and sepals in a highly variable quantity, the size commonly ranges from less than 0.2 mm to approximately 8 mm in height, and the gland appears to secrete when very young and to become non-functioning with maturity. Attachment: the thorns commonly are firmly attached. Orientation: major thorns tend to curve and to point to the base of the stem with the upper and lower edges being somewhat concave, the minor and minute thorns tend to be more upright and more perpendicular to the stems, and the stiff glandular hairs are disposed substantially perpendicular to the stems. Color: on upper areas of flowering shoots immature thorns commonly are Yellow-Green Group 144B to 144C and exhibit some red coloration of near Greyed-Purple Group 187B and 187C with small amounts of Greyed-Purple Group 185A, 186A through 187A with the red coloration being somewhat transparent and to appear to overlay the yellow-green base coloration, and more mature thorns commonly are near Brown Group 200C at the base, lightening to Brown Group 200D upwards, and commonly darkening through Brown Group 200B and 200A at the tip. More mature thorns commonly also include some coloration near Greyed-Orange Group 165A at the base shading continuously from Greyed-Orange Group 165B through and near Greyed-Orange Group 164A and Greyed-Orange Group 166C at the tip. The stiff glandular hairs are tipped with a reddish gland of near Greyed-Purple Group 185A to 187C.

Leaves:

Petioles.—Length: for a three-leaflet leaf commonly approximately 20 to 50 mm (approximately 35 mm on average), for a five-leaflet leaf commonly approximately 34 to 56 mm (approximately 40 mm on average), and for a seven-leaflet leaf approximately 20 to 36 mm (approximately 29 mm on average). Diameter: for a three-leaflet leaf 1 to 1.9 mm (approximately 1.3 mm on average), for a five-leaflet leaf approximately 1.7 mm, and for a seven-leaflet leaf approximately 1.8 mm. Texture: some minute prickles that are hooked towards the base commonly are present on the lower surface and along the midrib including the portion of the petiole that supports the stipule. These appear to be more common on five- and seven-leaflet leaves and rarely are found scattered on the upper surface. Color: the upper surface is primarily Yellow-Green Group 144A with some lightening to near Yellow-Green Group 144B, and the lower surface is primarily Yellow-Green Group 144B with some darkening to near Yellow-Green Group 144A.
