Abstract

A new variety of Hybrid Tea rose suitable for garden decoration, having flowers of warm pink with a cream reverse coloration.

Description

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

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

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Hybrid Tea Rose. It has as its seed parent the variety known as ‘WEKcryland’ (U.S. Plant Pat. No. 11,384) and as its pollen parent the variety known as ‘WEKsunspat’ (U.S. Plant Pat. No. 14,398).

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 rough peduncle with some small prickles, its wash of green along the central vein of the outermost petals, its unusual yellow green style color and its numerous large prickles on major stems, branches and new shoots. The plant has an upright growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kem 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. ‘WEKmoomar’ 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, ‘WEKcryland’ by the following combination of characteristics: whereas ‘WEKmoomar’ bears double flowers (about 26 to 33 petals) of warm pink with a cream reverse coloration, ‘WEKcryland’ bears double flowers with significantly heavier petalage (about 34 to 42 petals) of white coloration with a very fine pink edging. The new variety has an upright growing habit (about 52 to about 66 cm. spread at the widest point), whereas the seed parent has a significantly more spreading growing habit (about 80 to about 100 cm. spread at the widest point).

The new variety may be distinguished from its pollen parent, ‘WEKsunspat’ by the following combination of characteristics: whereas ‘WEKmoomar’ bears flowers of warm pink with a cream reverse coloration, ‘WEKsunspat’ bears flowers of soft apricot washed with green coloration. The new variety has an upright medium height growing habit (about 120 to about 140 cm. in height and about 52 to about 66 cm. spread at the widest point), whereas the pollen parent has a somewhat upright significantly taller and more spreading growing habit (about 160 to about 200 cm. in height and about 88 to about 110 cm. spread at the widest point).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is the seed parent ‘WEKcryland’.

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 November. 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 singly. Flowers are borne on strong somewhat short to medium length stems (about 25 to about 80 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a moderate tea to somewhat spicy fragrance.

BUD

The peduncle is about 3.2 to about 6.4 cm. in length, of moderately heavy caliper (about 0.3 to about 0.5 cm. in diameter), and usually erect. It is rough, with few stipitate glands, many hairs and some small prickles. Peduncle color is between 146B and 137D sometimes lightly suffused, especially on the side exposed to the sun, with between 187A and 183A.

Before the calyx breaks, the bud is about 1.5 to about 2.1 cm. in diameter at the widest point, about 2.0 to about 2.5 cm. in length, and moderately ovoid to somewhat pointed in shape. The surface of the bud bears some very long foliaceous appendages and few hairs, usually with slender entire foliaceous parts extending beyond the tip of the bud about ¼ more of its length. Bud color is between 137B and 137A sometimes lightly suffused, especially on the side exposed to the sun, with between 187A and 183A.

The sepals are about 2.8 to about 4.2 cm. in length and about 0.8 to about 1.1 cm. in width at the widest point. The outer surface color of the sepal is between 137B and 137A sometimes lightly suffused, especially on the side exposed to the sun, with between 187A and 183A. The inner surface color of the sepal is between 137B and 138B and covered with fine wooly tomentum; sepal margins are lined with some stipitate glands and hairs.

The receptacle of the flower is of somewhat short length (about 0.4 to about 0.6 cm.) and moderately thin in caliper (about 0.8 to about 1.1 cm. in diameter). The receptacle is somewhat urn-shaped in form with a flat top. Its surface is very smooth with few hairs and with thick fleshy walls. The receptacle color is between 144A and 138A.

As the petals open (after the calyx breaks), the bud is about 2.4 to about 2.8 cm. in diameter at the widest point, about 3.0 to about 4.0 cm. in length, and in moderately ovoid form. The color of the under surfaces of the newly opened petals is between 4D and 158C often washed along the central vein of the outermost petals with between 145A and 145B and lightly blushed mostly on the edge of the petals with between 61B and 61C. There is no visible change in coloration at the point where the petal attaches. On the upper surfaces of the newly opened petals, the color at the base of the petal is between 1D and 2D that gradually suffuses toward the center of the petal to near 55C, usually moderately blushed toward the petal edge with between 63B and 61C. There is no visible change in coloration at the point where the petal attaches.

BLOOM

When fully open, the bloom ranges from about 10.5 to about 13.9 cm. in diameter. Petalage is double with about 26 to 33 petals and about 2 to 6 petaloids irregularly arranged. When partially open, the bloom form is somewhat high centered to moderately cupped, and the petals are moderately tightly spiraled to cupped with petal edges slightly reflexed outward. When fully open, the bloom form is more cupped, and the petals are loosely cupped with petal edges moderately reflexed outward.

PETALS

The substance of the petals is moderately heavy and somewhat thick, with upper surfaces moderately satiny to somewhat shiny and under surfaces moderately shiny. The petals are about 4.8 to about 6.9 cm. in length and about 4.1 to about 7.2 cm. in width at the widest point. Petal margins are entire.

The outer petals are rounded in shape with rounded apices.

The inner petals are broadly obovate in shape with rounded apices and sometimes slightly notched with one notch.

Petaloids are about 3.1 to about 5.0 cm. in length and about 2.7 to about 4.6 cm. in width at the widest point. Petaloids are irregularly shaped moderately rounded to somewhat obovate with rounded apices.

NEWLY OPENED FLOWER

On the under surfaces of the outer petals, the color at the base of the petal is between 155A and lighter than 2D gradually suffusing on the petal to between 155A and 155C, sometimes lightly blushed toward the petal edge with between 64C and 61C. There is no visible change in coloration at the point where the petal attaches. On the upper surfaces of the outer petals, the color at the base of the petal is lighter than between 1D and 2D gradually suffusing toward the center of the petal to between 62D and lighter than 55D, usually lightly blushed toward the petal edge with between 64C and 61C. There is no visible change in coloration at the point where the petal attaches.

On the under surfaces of the intermediate and inner petals, the color at the base of the petal is between 155A and lighter than 2D gradually suffusing on the petal to between 155A and 158D, sometimes lightly blushed toward the petal edge with between 64C and 61C. On the upper surfaces of the intermediate and inner petals, the color at the base of the petal is lighter than between 1D and 2D gradually suffusing toward the center of the petal to between 63D and 62B, usually moderately blushed toward the petal edge with between 64C and 55A.

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 lighter than between 1D and 2D at the base gradually suffusing toward the center of the petal to between 63D and 62B, usually moderately blushed toward the petal edge with between 64C and 55A.

THREE-DAY-OLD FLOWER

On the under surfaces of the outer, intermediate and inner petals, the color at the base of the petal is between 155A and lighter than 4D gradually suffusing on the petal to between 155D and 155C, sometimes lightly blushed toward the petal edge with between 64C and 61C. There is no visible change in coloration at the point where the petal attaches. On the upper surfaces of the outer, intermediate and inner petals, the color at the base of the petal is lighter than between 2D and 4D gradually suffusing toward the center of the petal to between 62D and 65D, sometimes lightly blushed toward the petal edge with between 64C and 61C. There is no visible change in coloration at the point where the petal attaches.

The general tonality of the three-day-old flower is lighter than between 2D and 4D at the base gradually suffusing toward the center of the petal to between 62D and 65D, sometimes lightly blushed toward the petal edge with between 64C and 61C.

On the spent bloom, the petals usually drop off cleanly.

In November 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.
