Floribunda rose plant named ‘WEKcobeju’

Abstract

A new variety of Floribunda rose suitable for garden decoration, having flowers of smoky lavender and rusty red-orange coloration.

Description

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘WEKcobeju’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Floribunda Rose. It has as its seed parent the variety known as ‘WEKcocbeb’ (U.S. Plant Pat. No. 18,870) and as its pollen parent the variety known as ‘WEKvossutono’ (U.S. Plant Pat. No. 18,473).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its unique flowers of smoky lavender and rusty red-orange coloration, its mucronate outer and intermediate petals apices and its heavy purple suffusion on the petals as they age. The plant has a bushy rounded growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County and Pomona, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKcobeju’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’ (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘WEKcocbeb’ by the following combination of characteristics: whereas ‘WEKcobeju’ bears flowers of smoky lavender and rusty red-orange coloration with double petalage (about 16 to 24 petals), ‘WEKcocbeb’ bears flowers of brilliant scarlet coloration with a white reverse and with significantly lesser petalage (about 10 to 17 petals). The new variety has a bushy rounded growing habit (about 120 to about 160 cm. in height), whereas the seed parent has a bushy moderately spreading significantly shorter growing habit (about 80 to about 100 cm. in height).

The new variety may be distinguished from its pollen parent, ‘WEKvossutono’ by the following combination of characteristics: whereas ‘WEKcobeju’ bears flowers of smoky lavender and rusty red-orange coloration with double petalage (about 16 to 24 petals), ‘WEKvossutono’ bears butter gold flowers with significantly heavier petalage (about 30 to 45 petals). The new variety has a bushy rounded growing habit (about 120 to about 160 cm. in height), whereas the pollen parent has a compact and bushy significantly shorter growing habit (about 70 to about 85 cm. in height).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety has very unique characteristics that distinguish it from any other commercially available cultivar. No variety can compare to ‘WEKcobeju’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Pomona, Calif. in the month of October. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers in clusters of two to eleven or more per stem. Flowers are borne in regular rounded clusters on strong medium length stems (about 18 to about 44 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a slight apple-like to somewhat pear-like fragrance.

BUD

The peduncle is about 1.6 to about 4.2 cm. in length, of slender caliper (about 0.1 cm to about 0.2 cm. in diameter), and usually erect. It is moderately smooth, with some stipitate glands. Peduncle color is between 146B and 146A sometimes lightly suffused, especially on the side exposed to the sun, with between 183B and 187B.

Before the calyx breaks, the bud is about 0.9 to about 1.6 cm. in diameter at the widest point, about 1.4 to about 1.9 cm. in length, and pointed in shape. The surface of the bud bears few foliaceous appendages and some stipitate glands, usually with slender entire foliaceous parts extending beyond the tip of the bud about ½ or more of its length. Bud color is between 146B and 146A sometimes lightly suffused, especially on the side exposed to the sun, with between 183B and 187B.

The sepals are about 2.2 to about 3.3 cm. in length and about 0.6 to about 1.0 cm. in width at the widest point. The outer surface color of the sepal is between 146B and 146A sometimes lightly suffused, especially on the side exposed to the sun, with between 183B and 187B. The inner surface color of the sepal is near 138B broadly bordered by near 137A. After the sepals open, the inner surface color is sometimes lightly suffused, especially on the area exposed to the sun, with between 187A and 187B. The inner surface of the sepal is covered with fine wooly tomentum; sepal margins are lined with few stipitate glands and many hairs.

The receptacle of the flower is of medium length (about 0.3 to about 0.6 cm.) and average in caliper (about 0.6 to about 0.8 cm. in diameter). The receptacle is cup-shaped in form. Its surface is smooth with few hairs and stipitate glands and with thick fleshy walls. The receptacle color is between 146B and 146A.

As the petals open (after the calyx breaks), the bud is about 1.4 to about 2.4 cm. in diameter at the widest point, about 2.1 to about 3.1 cm. in length, and moderately ovoid to somewhat pointed in form. The color at the base of the under surfaces of the newly opened petals is between 53B and 60B gradually suffusing toward the edge of the petals with between 53A and 60A. At the point where the petal attaches, there is a moderately large zone of between 13B and 12A. The color at the base of the upper surfaces of the newly opened petals is between 46B and 45B often heavily blushed especially on the upper ⅓ of the petal with between 187A and 60A. At the point where the petal attaches, there is a moderately large zone of between 13B and 12A.

BLOOM

When fully open, the bloom ranges from about 6.3 to about 10.1 cm. in diameter. Petalage is double with about 16 to 24 petals and about 7 to 12 petaloids irregularly arranged. When partially open, the bloom form is moderately cupped to somewhat high centered, and the petals are loosely spiraled to cupped with petal edges somewhat reflexed outward. When fully open, the bloom form is more cupped to somewhat flat, and the petals are loosely cupped to moderately undulated with petal edges moderately reflexed outward and sometimes somewhat reflexed inward.

PETALS

The substance of the petals is somewhat slight and of moderately thin thickness, with upper surfaces moderately satiny and under surfaces slightly shiny to matte. The petals are about 2.1 to about 4.1 cm. in length and about 1.2 to about 3.4 cm. in width at the widest point. Petal margins are entire.

The outer petals are moderately obovate in shape with mucronate apices.

The inner petals are moderately obovate to somewhat oblanceolate in shape with rounded apices.

Petaloids are about 0.6 to about 1.9 cm. in length and about 0.3 to about 1.4 cm. in width at the widest point. Petaloids are irregularly shaped somewhat oblanceolate to subulate with rounded apices.

NEWLY OPENED FLOWER

The under surface color of the outer, intermediate and inner petals is between 53C and 184D. At the point where the petal attaches, there is a moderately large zone of between 13C and 12B. The upper surface color of the outer, intermediate and inner petals is between 44C and 45C usually lightly overlaid with a wash of between 77A and 79C. At the point where the petal attaches, there is a moderately large zone of between 13C and 12B.

The under and upper surface colors of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the newly opened flower is between 44C and 45C usually lightly overlaid with a wash of between 77A and 79C.

THREE-DAY-OLD FLOWER

The under surface color of the outer, intermediate and inner petals is between 53C and 185C. At the point where the petal attaches, there is a moderately large zone of between 11B and 10B. The upper surface color of the outer, intermediate and inner petals is between 47C and 44D usually lightly overlaid with a wash of between 77A and 79C. At the point where the petal attaches, there is a moderately large zone of between 8B and 7D.

The under and upper surface colors of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the three-day-old flower is between 47C and 44D usually lightly overlaid with a wash of between 77A and 79C.

On the spent bloom, the petals usually drop off cleanly, aging to between 60C and 186A on the under surface and to between 48B and 51B on the upper surface usually heavily overlaid with a wash of between 79D and 79C.

In October in Pomona, Calif., blooms on the bush growing outdoors generally last about four to five days. Cut roses from plants grown outdoors and kept at normal indoor living temperatures generally last about four to five days.

MALE REPRODUCTIVE ORGANS
