Abstract

This invention relates to a new and distinct variety of hybrid tea rose plant cv. Arocore, particularly suited for garden decoration, identified by its dark red flower buds, and long-lasting medium red blooms having ruffled petals.

Description

The present invention relates to a new and distinct variety (cv. Arocore) of rose plant of the hybrid tea class. The plant is a moderately tall, bushy, hardy outdoor seedling cultivated for garden decoration. It was first originated by Jack E. Christensen in Ontario, Calif., U.S.A. under conditions of careful control and observation, and has as its seed parent the floribunda rose, Merci (U.S. Plant Pat. No. 3,144), and as its pollen parent, the hybrid tea rose Pharoah (U.S. Plant Pat. No. 2,859).
The new rose cv. Arocore is particularly distinguishable from other commercialized rose cultivars by the following combination of characteristics: its upright-spreading and vigorous growing plants of average height; its abundant dark red flower buds, borne on long strong stems; its dark red open blooms comprised of long-lasting, ruffled petals; its slight fruity fragrance; and its above average disease resistance and cold hardiness.
Arocore holds its distinguishing characteristics through succeeding propagations by budding and cuttings.
The new variety cv. Arocore may be distinguished from its seed parent, Merci, by the following combination of characteristics: Whereas Merci is a floribunda rose, Arocore is a hybrid tea rose. The petal color of Arocore is dark red, whereas the petal color of Merci is a medium-red.
The new variety may be distinguished from its pollen parent, Pharoah, by the following combination of characteristics: Whereas the flower color of Pharoah is bright orange red, the flower color of Arocore is dark red.
The accompanying drawing illustrates the new variety in color as grown in Somis, Calif., and shows the flowering thereof from bud to full bloom.
The descriptive matter which follows pertains to roses of the new variety grown outdoors in Somis, Calif., and is believed generally to apply to plants grown under similar conditions of soil and climate elsewhere. Plants and flowers of the new variety grown in other locations may vary in slight detail according to the climatic, soil and cultural conditions under which the variety is grown.
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.
FLOWER
The new variety usually bears a single flower per a stem. Flower stems are strong and of medium length for the class. Outdoors, the plant blooms very freely, abundantly and continuously during the growing season. Blooms have a slight to moderate fruity fragrance.
BUD
The peduncle is short to average in length for the class, of average caliper, strong and bending. The peduncle is moderately rough with numerous stipitate glands and few prickles. Bud color is near Yellow-Green 144A. Parts of the bud exposed to sunlight are near Red-Purple 59A in color.
Before the calyx breaks, the bud is average in size for the class, of average length, pointed and ovoid in form with a conspicuous neck. There are many foliaceous appendages and stipitate glands on the surface of the bud. The bud usually bears deeply serrate foliaceous parts, extending beyond the tip of the bud equal to 3/4 or more the bud length.
As the calyx breaks, petals exposed to sunlight are near Red 46A in color; sepal color is near Green 141C and near Red-Purple 59A where exposed to the sun.
The inner surface of the sepals is lined with a fine wooly tomentum. Sepal margins are lined with stipitate glands, gland-tipped cilia and hairs.
As the first petal opens, buds are average in size for the class, average to long in length and pointed to ovoid in form. Color of the outside of the bud petals is a dark red, near Greyed-Purple 185A toward the top of the bud and a darker red, near Red-Purple 187B, on the lower two thirds of the bud. The inside surface of the bud petals is near Red-Purple 185A in color.
The bud opens up well and is not prevented from opening by cold, hot or dry weather.
BLOOM
The size of the bloom when fully open is average for the class, about 4 to about 41/2 inches in diameter. Petalage is double, averaging from about 45 to about 48 petals arranged irregularly, plus 5 to 6 petaloids.
Blooms at one half open are somewhat low centered to flat-topped in form, with petals moderately to very cupped to ruffled. Petal edges are somewhat flat.
When fully open, the blooms are somewhat flat, with loosely cupped petals, and flat petal edges.
The petals are of moderate to heavy substance, of average thickness, and slightly velvety on the inside and outside surface. Outside petals are nearly round in shape, sometimes scalloped, the apices usually bearing 2 to 3 notches. Intermediate petals are nearly round to broadly obovate in shape with apices bearing zero to one notch. Inside petals are nearly round to broadly obovate, with rounded apices usually bearing zero to one notch.
Petal colors may be modified by being blotched or overlaid with other colors under certain seasonal conditions.
The following paragraph describes the color values observed in a newly opened flower from a plant of the new variety grown outdoors in Somis, Calif. in November of 1987.
The color of the outside surface of the outside petals is comprised of dark red blends of between near Red-Purple 187A and Red-Purple 187B. The inside surface of the outer petals is near Greyed-Purple 185A with a very small basel attachment zone of near Yellow 7A. The outside surface of the intermediate petals is near Greyed-Purple 185A. The inside surface of the intermediate petals is near Red 46A with a very small basel attachment zone near Yellow 7A. The outside surface of the inner petals is near Red 46A. The inside surface of the inner petal is near Red 46A with basel attachment zone near Yellow 7A.
The following paragraph describes the color values observed in a flower open for three days outdoors from a plant of the new variety in November, 1987 at Somis, Calif.
The color of the outside surface of the outside petals is near Greyed-Purple 185A. The inside surface of the outside petal is near Red 46A, with a small basel attachment zone near Yellow 7A in color. The color of the outside surface of the inside petal is near Red 46A. The color of the inside surface of the inside petal is near Red 46A with a small basal attachment zone near Yellow 7A.
The generally color effect of the newly opened flower is a rich, vibrant dark red, near Red 46A on the outer petals.
After being open three days, the general color effect of the flower is near Red 46A margined with a darker red.
Petals usually drop off cleanly and are not particularly affected by hot or dry weather.
Flowers grown in the month of September last from 4 to 5 days on a bush in the garden. Cut flowers from rose plants grown outdoors in September last from 5 to 6 days when kept at living room temperatures.
