Description

This invention relates to a new variety of hybrid tea rose cv. Aromiclea. The plant is a tall, hardy outdoor seedling of the bush type, cultivated for garden decoration and very suitable for cut flower production. It was bred by Jack E. Christensen in Ontario, Calif., and has as its seed parent an undisseminated seedling of the cross [Camelot (U.S. Plant Pat. No. 2,371).times.First Prize (U.S. Plant Pat. No. 2,774)].times.Typhoo Tea (U.S. Plant Pat. No. 3,845), and as its pollen parent, Lolita.

The new variety cv. Aromiclea may be distinguished from other presently available commercial rose cultivars by the following combination of characteristics: its large blossoms of a unique chatoyant orange coloration, essentially as described and illustrated herein; its sweet flower scent, long, strong stems, and urn-shaped buds, which make the flowers very suitable for cutting; its unusually heavy, leathery and very glossy foliage; its nearly continual bloom and well-branched habit, which make it an attractive garden plant; and its vigor, above-average hardiness, well-above-average disease resistance, and attractive flower finish, which make it desirable as a low-maintenance plant for landscaping. Aromiclea holds these distinguishing characteristics through succeeding propagations by budding.

The new rose may be distinguished from its seed parent, an undisseminated seedling of the cross (Camelot.times.First Prize).times. Typhoo Tea, by the following combination of characteristics: Whereas the seed parent bears flowers of a coral pink coloration with a distinct white underside, Aromiclea bears flowers of a chatoyant orange coloration, essentially as described and illustrated herein. The new variety bears flowers with 29 to 34 petals, whereas the parent seedling bears flowers of distinctly lighter petalage (20 to 25 petals). The parent plant produces a mature bush of medium height and upright-spreading habit, whereas the new cultivar produces a significantly taller bush of very upright habit.

The new vareity may be distinguished from its pollen parent, Lolita, by the following combination of characteristics: Whereas Lolita produces flowers of a blended golden apricot coloration, Aromiclea produces flowers of a chatoyant orange coloration, essentially as described and illustrated herein. Lolita bears short flower buds that are ovoid in shape, whereas the new cultivar bears significantly longer flower buds with a more slender shape. Under the growing conditions of southern California, Lolita bears flowers of heavy petalage (40 to 45 petals), whereas Aromiclea bears flowers of significantly lighter petalage (29 to 34 petals).

The accompanying drawing illustrates the plant in color and shows the flowering thereof from bud to full bloom. Throughout this specification, color names beginning with a small letter signify that the name of that color as used in common speech is aptly descriptive. Color names beginning with a capital letter designate values based upon the R.H.S. Colour Chart of The Royal Horticultural Society of London, England.

The descriptive matter which follows pertains to roses of the new variety grown in southern California and is believed to apply to plants of the variety grown in similar conditions of soil and climate elsewhere.

FLOWER

The new variety usually bears its flowers singly, sometimes two to three flowers per stem, in irregular, rounded clusters. Flowers are borne on strong stems that are long for the class. Outdoors, the plant blooms very abundantly and nearly continuously during the growing season. It has a moderate, spicy to fruity fragrance.

BUD

The peduncle is of average length for the class, of average to heavy caliper, strong and erect. It is moderately smooth, with some stipitate glands, and between Yellow-Green 144B and Green 138A in color.

Before the calyx breaks, the bud is medium to large in size for the class, medium-length to long, and pointed in form. The surface of the bud bears a few foliaceous appendages and stipitate glands. Slender, shallowly serrate foliaceous parts are usually present, extending beyond the tip of the bud and equal to one half or more of its length.

As the calyx breaks, bud color is between Red 45C and Red 45B.

The inner surface of the sepals has a woolly tomentum; margins are lined with stipitate glands and hairs.

As the first petal opens, the bud is average to large in size for the class, long, and pointed to urn-shaped in form. The outside surface of the newly-opening petals displays a basal attachment zone near Yellow 12A that slowly suffuses to between Orange 24C and Greyed-Orange 170D and is often blushed with between Orange-Red 34C and Red 45B. The inside surface of the opening petals displays a smaller basal attachment zone near Yellow 12A, which quickly suffuses to between Orange-Red 30A and Greyed-Orange 170A. The bud opens up well and is not retarded or prevented from opening by cold, hot, wet, or dry weather.

BLOOM

When fully open, the bloom is large for the class, ranging from 41/2 to 51/2 inches in diameter. Petalage is double, with petals arranged regularly; there are from 29 to 34 petals present and from 1 to 6 petaloids. When half open, the bloom is very high-centered, and the petals are moderately cupped with petal edges moderately reflexed outward. When fully open, the bloom is somewhat cupped, with petals loosely cupped and petal edges undulated and reflexed outward.

The petals are of moderately heavy substance and thick, with insides slightly velvety and outsides slightly satiny. The outside petals are nearly round to broadly obovate in shape, sometimes scalloped, with rounded apices. The intermediate petals are broadly obovate and sometimes scalloped, with rounded apices. The inner petals are narrowly obovate, sometimes scalloped to irregular, with rounded apices. Petal colors may be modified by being bordered or blotched or shaded or washed or tinted with other colors.

The paragraphs immediately following describe the color values observed in a newly opened flower on a plant grown outdoors in Somis, Calif., in the month of September.

The outside surface of the outside petals displays a basal attachment zone near Yellow 9C that suffuses to between Orange 24C and Orange 29C and is often blushed with between Red 47B and Orange-Red 35A. The inside surface of the outside petals displays a basal attachment zone near Yellow 9C that slowly suffuses to between Orange-Red 35B and Yellow-Orange 20C, with petal edges blushed as deeply as between Orange-Red 34A and Red 45C.

The outside surfaces of the intermediate and inner petals have the same coloration as the outside surface of the outside petals, but without blushing.

The inside surface of the intermediate petals has the same coloration as the inside surface of the outside petals, but with less blushing. The inside surface of the inner petals has the same coloration as the inside surface of the outside petals, but with no blushing.

The paragraphs immediately following describe the color values observed in a bloom which had been open for three days on a plant grown outdoors in Somis, Calif., in the month of September.

The outside surfaces of the outside and inside petals display a basal attachment zone near Yellow 10A, which suffuses to between Yellow-Orange 23D and Orange-Red 33D with petal edges colored as deeply as near Red 47C. The inside surfaces of the outside and inside petals display a basal attachment zone near Yellow 10A which slowly suffuses to between Red 37C and Orange 29C and is predominantly blushed with between Red 40A and Red 45A.

In general, the blossoms exhibit a unique chatoyant orange coloration. The general color effect of the newly opened flower is between Orange-Red 35B and Yellow-Orange 20C, with outer petals blushed to between Orange-Red 34A and Red 45C. After three days, the general color effect of the flower is predominantly blushed to between Red 40A and Red 45A. The petals usually drop off cleanly and are not particularly affected by hot, wet, or dry weather.

In September, flowers on plants of the new variety grown in the garden last on the bush from 4 to 5 days. Flowers cut from plants grown outdoors in September last from 5 to 6 days at living-room temperatures.
