Abstract

A new variety of Climbing rose suitable for garden decoration, having flowers of deep velvet red coloration.

Description

Classification: The present invention relates to a new Rosa hybrida plant.
Variety denomination: The new plant has the varietal denomination ‘WEKamrav’.
BACKGROUND OF THE INVENTION
This invention relates to a new and distinct variety of Climbing Rose. It has as its seed parent the variety known as ‘MEIcauf’ (U.S. Plant Pat. No. 7,718) and as its pollen parent the variety known as ‘FRYtrooper’ (U.S. Plant Pat. No. 9,211).
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 combination of characteristics: its even deep velvet red coloration that last throughout the life of the flower, its conspicuous neck, its red suffusion on the petiolule and its numerous stipitate glands on the stipules of the new shoots. The plant has a spreading climbing growing habit, suitable for outdoor garden decoration.
Asexual reproduction of the new variety by budding as performed in Kern County and Upland, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKamrav’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’.
COMPARISON WITH PARENTS
The new rose may be distinguished from its seed parent, ‘MEIcauf’ by the following combination of characteristics: whereas ‘WEKamrav’ bears medium sized flowers (about 4.8 to about 7.2 cm. in diameter) of deep velvet red coloration, ‘MEIcauf’ bears significantly larger flowers (about 13.0 to about 14.0 cm. in diameter) of turkey red coloration. The new variety is classified as a climbing rose with a spreading climbing growing habit, whereas the seed parent is classified as a hybrid tea rose with an erect and upright significantly shorter growing habit.
The new variety may be distinguished from its pollen parent, ‘FRYtrooper’ by the following combination of characteristics: whereas ‘WEKamrav’ bears flowers of deep velvet red coloration with double petalage (about 25 to 36 petals), ‘FRYtrooper’ bears flowers of clear red coloration with significantly lesser petalage (about 18 to 22 petals). The new variety is classified as a climbing rose with a spreading climbing growing habit, whereas the pollen parent is classified as a shrub rose with a bushy, compact and upright significantly shorter growing habit.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The new variety may be distinguished from its closest commercially available cultivar, ‘WEKsamsou’ by the following combination of characteristics: whereas ‘WEKamrav’ bears flowers of deep velvet red coloration with double petalage (about 25 to 36 petals), ‘WEKsamsou’ bears flowers of medium cherry red coloration with significantly heavier petalage (about 36 to 50 petals). The new variety bears moderately small foliage (about 7.4 to about 11.9 cm. in length and about 5.2 to about 8.1 cm. in width), whereas the closest commercially available cultivar bears significantly larger foliage (about 7.2 to about 13.3 cm. in length and about 7.0 to about 10.2 cm. in width). ‘WEKamrav’ has a spreading climbing medium height growing habit with climbing canes about 150 to about 250 cm. in length, whereas ‘WEKsamsou’ has a spreading growth habit with significantly longer climbing canes of about 250 to about 380 cm. in length.
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 of London, England (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 Upland, 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.
BOTANICAL DESIGNATION
The new variety botanical designation is Rosa hybrida ‘WEKamrav’.
FLOWER
The new variety sometimes bears its flowers singly, sometimes in clusters of two to six or more per stem. Flowers may be borne in regular rounded clusters on strong medium length to long stems (about 38 to about 100 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a very slight tea fragrance.
BUD
The peduncle is about 2.4 to about 5.8 cm. in length, of somewhat slender caliper (about 0.2 to about 0.3 cm. in diameter), and usually erect. It is moderately smooth, with some stipitate glands and few hairs. Peduncle color is between 144A and 146B often heavily suffused, especially on the side exposed to the sun, with between 183A and 187B.
Before the calyx breaks, the bud is about 0.9 to about 1.4 cm. in diameter at the widest point, about 1.1 to about 1.8 cm. in length, and pointed to somewhat ovoid in shape with a conspicuous neck. The surface of the bud bears some foliaceous appendages and some stipitate glands and hairs, usually with slender entire foliaceous parts extending beyond the tip of the bud about ¼ or more of its length. Bud color is between 144A and 146A often heavily suffused, especially on the side exposed to the sun, with between 183A and 187B.
The sepals are about 1.3 to about 2.5 cm. in length and about 0.5 to about 0.8 cm. in width at the widest point. The outer surface color of the sepal is between 144A and 146A often heavily suffused, especially on the side exposed to the sun, with between 183A and 187B. The inner surface color of the sepal is between 137A and 139D and covered with fine wooly tomentum; sepal margins are lined with few stipitate glands and numerous hairs.
The receptacle of the flower is of very long length (about 0.6 to about 1.1 cm.) and average in caliper (about 0.6 to about 0.8 cm. in diameter). The receptacle is moderately oblong to somewhat ovoid in form. Its surface is very smooth with some hairs and with thick fleshy walls. The receptacle color is between 144A and 146A sometimes moderately suffused, especially on the side exposed to the sun, with between 183A and 187B.
As the petals open (after the calyx breaks), the bud is about 1.5 to about 2.2 cm. in diameter at the widest point, about 1.5 to about 2.6 cm. in length, and moderately ovoid in form. The color of the under surfaces of the newly opened petals is between 187B and 53A. At the point where the petal attaches, there is a very small zone of between 5C and 4B. The color of the upper surfaces of the newly opened petals is between 53A and 46A. At the point where the petal attaches, there is a small zone of between 13A and 14B.
BLOOM
When fully open, the bloom ranges from about 4.8 to about 7.2 cm. in diameter. Petalage is double with about 25 to 36 petals and about 4 to 10 petaloids irregularly arranged. When partially open, the bloom form is cupped to globular and the petals are moderately tightly spiraled to cupped with petal edges somewhat reflexed outward. When fully open, the bloom form is cupped and the petals are loosely cupped with petal edges somewhat reflexed outward.
PETALS
The substance of the petals is moderately heavy and of medium thickness, with upper surfaces moderately velvety and under surfaces very shiny. The petals are about 1.5 to about 3.5 cm. in length and about 1.0 to about 3.7 cm. in width at the widest point. Petal margins are entire.
The outer petals are moderately rounded to somewhat obovate in shape with mostly mucronate and sometimes rounded apices.
The inner petals are obovate in shape with mostly mucronate and sometimes rounded apices.
Petaloids are about 0.8 to about 2.6 cm. in length and about 0.5 to about 1.3 cm. in width at the widest point. Petaloids are irregularly shaped somewhat obovate to oblanceolate with rounded apices.
NEWLY OPENED FLOWER
The under surface color of the outer petals is between 53A and 46A. At the point where the petal attaches, there is a very small zone of between 5C and 4B. The upper surface color of the outer petals is between 46A and 45A. At the point where the petal attaches, there is a small zone of between 13C and 14C.
The under surface color of the intermediate and inner petals is lighter than between 53A and 46A. The upper surface color of the intermediate and inner petals is between 46A and 45A.
The under and upper surface color 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 46A and 45A.

The under and upper surface color 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 46A and 45B.
On the spent bloom, the petals usually drop off cleanly.
In October in Upland, 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
Stamens are average in number (average about 85) and are arranged regularly about the pistils; a few are mixed with petaloids. The filaments are of moderately short length (about 0.4 to about 0.8 cm.) most with anthers. Filaments are between 12B and 13C in color sometimes lightly suffused with between 33A and 33B. The anthers are moderately small for the class and all open approximately at the same time. Anther color is between 22A and 22C when immature and between 200A and 163C at maturity. Pollen is somewhat abundant and between 20A and 22B in color.
FEMALE REPRODUCTIVE ORGANS
Pistils vary in number (average about 70). The styles are moderately even, short in length (about 0.2 to about 0.5 cm.), somewhat thin in caliper and loosely bunched. Stigma color is between 11C and 12D. Style color is between 2D and 1D usually moderately suffused with between 53A and 53B. Ovaries are usually all enclosed in the calyx.
Hips are of moderately long length (about 1.7 to about 2.3 cm.), globular to almost round in form, and between 34B and 33B in color when ripe. The hip surface is smooth with thick fleshy walls. The sepals are somewhat fugacious and usually straight in shape.

The under surface color of the young leaf is between 147B and 146B, usually heavily suffused with between 187B and 183A.
The rachis is somewhat light in caliper and rough. The upper side is moderately deeply grooved with few hairs and stipitate glands on the edges of the grooves. The under side of the rachis is rough with some hairs and few stipitate glands and small prickles. The rachis color is between 145A and 144A often moderately suffused on the young leaves with between 187A and 187B.
The stipules are about 1.1 to about 1.7 cm. in length and of medium width (about 0.4 to about 0.5 cm.) with moderately long straight points that usually turn out at an angle of more than 45 degrees and often recurve toward the stem. The stipules color is between 146C and 146A often moderately suffused with between 187A and 187B. The stipule margin and under side of the stipule on the new shoots are often lined and covered with numerous stipitate glands.
The petiole is somewhat light in caliper and rough. The upper side is moderately deeply grooved with few hairs and stipitate glands on the edges of the grooves. The under side of the petiole is rough with some hairs and few stipitate glands and small prickles. The petiole is about 0.9 to about 2.2 cm. in length and about 0.1 to about 0.15 cm in diameter at the widest point. The petiole color is between 145A and 144A often moderately suffused on the young leaves with between 187A and 187B. The petiolule is often moderately suffused with between 187A and 187B.
