| Abstract: |
This invention relates to a new and distinct variety of hybrid tea rose plant cv. Arokish, particularly suited for garden decoration, identified by its pure white flowers of large size having a strong, penetrating fruity fragrance. |
| Claim: |
I claim:
1. A new and distinct variety of hybrid tea rose plant cv. Arokish, and the parts thereof, being particularly characterized by its vigorous, upright and strong growing plants; its veryfreely blooming, pure white flowers of large size, borne on medium to long strong stems; and the strong and penetrating fruity fragrance of its flowers, substantially as described and illustrated herein. |
| Description: |
The present invention relates to a new and distinct variety (cv. Arokish) of rose plant of the hybrid tea class. The plant is a bushy outdoor seedling cultivated for garden decoration. It was first originated by Jack E. Christensen inOntario, Calif., U.S.A. under conditions of careful control and observation, and has as its seed parent the floribunda rose, Deep Purple (U.S. Plant Pat. No. 4,672), and as its pollen parent, an unnamed rose seedling selected from the progeny of thecross fertilization between the hybrid tea rose, Ivory Tower (U.S. Plant Pat. No. 4,658) and the floribunda rose, Angel Face (U.S. Plant Pat. No. 2,792).
The new rose cv. Arokish is particularly distinguishable from other commercialized rose cultivars by the following combination of characteristics: its vigorous, upright, and strong growing plants; its very freely blooming, pure white flowers oflarge size, borne on medium to long strong stems; and the strong and penetrating fruity fragrance of its flowers.
Arokish holds its distinguishing characteristics through succeeding propagations by budding and cuttings.
The new variety cv. Arokish may be distinguished from its seed parent, Deep Purple, by the following combination of characteristics: Whereas Deep Purple is a floribunda rose, Arokish is a hybrid tea rose. The petal color of Arokish is white,whereas the petal color of Deep Purple is a mauve-pink.
The new variety may be distinguished from its pollen parent, an unnamed seedling (Ivory Tower x Angel Face), by the following combination of characteristics: Whereas the flower color of the pollen parent is lavender, the flower color of Arokishis white. Whereas the flower fragrance of the pollen parent is strong and citrus-like, the flower fragrance of Arokish is strong, penetrating and fruity, although not quite as strong as the flower fragrance of the pollen parent. Arokish is morevigorous and stronger growing than its pollen parent.
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 followspertains 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 inslight 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 stem. Flowers are sometimes borne two to three per stem, in irregular clusters. Flower stems are of average strength to strong for the class. A few flower stems are weak. Flower stems are ofmedium length to long for the class. Outdoors, the plant blooms very freely and continuously during the growing season. Flowers have a strong and penetrating fruity fragrance.
BUD
The peduncle is of average length for the class, of average caliper, strong and erect. The peduncle is mostly smooth with some stipitate glands. Bud color is near Yellow-Green 146C.
Before the calyx breaks, the bud is average in size for the class, of average length, and ovoid in form with a conspicuous neck. There are a few stipulate glands and a glandular bloom on the surface of the bud. The bud lacks foliaceous partswhich extend beyond the tip of the bud.
As the calyx breaks, petals ar near White 155B in color; sepal color is near Green 146B.
The inner surface of the sepals is lined with a fine wooly tomentum. Sepal margins are lined with stipitate glands.
As the first petal opens, buds are average in size for the class, long and urn-shaped. The color of the outside of the bud petals is near White 155A. The inner surface of the bud petals is near Yellow-White 158B in color.
The bud opens up well and is not prevented from opening by cold, hot, wet or dry weather.
BLOOM
The size of the bloom when fully open is average for the class, about 31/2 to about 4 inches in diameter. Petalage is very double, averaging from about 32 to about 34 petals arranged regularly, plus 2 to 5 petaloids.
At one half open, blooms are somewhat high centered to flat-topped in form, with petals cupped and petal edges somewhat reflexed outward.
When fully open, the blooms are cupped, with petals more cupped and petal edges moderately reflexed outward.
The petals are of heavy substance, of average thickness, satiny on the inside surface and slightly satiny on the outside surface. Outside petals are nearly round in shape, sometimes scalloped, with rounded apices bearing 1 to 2 notches. Intermediate petals are nearly round to slightly obovate in shape with rounded apices bearing zero to one notch. Inside petals are obovate with rounded apices usually bearing zero to one notch.
Petal colors may be modified by being washed with other colors.
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 and inside surface of the outside and intermediate petals is almost totally white, near White 155B in color, with slight greenish tints of near Green White 157C near the basal attachment zone. The color of the outsideand inside surface of the inner petals is near Yellow-White 158D.
The folowing 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 a white, slightly tinted with green, near Green-White 157D. The color of the inside surface of the outside petals is near White 155D. The color of the outside and inside surface of theinside petal is a warm, yellow-tinted white, near White 158D, blending into near White 155D at the top half of the petal.
The general color effect of the newly opened flower is almost a pure white, near White 155D, with a warm, very light yellow tint near Yellow-White 158D.
After being open three days, the general color effect of the flower is very near that of the newly opened flower with a slightly greater yellow tint.
Petals usually persist and are not particularly affected by cold, hot, wet or dry weather.
Flowers grown in the month of September last from 3 to 4 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.

Pollen is produced in sparse to moderate quantities and is near Yellow-Orange 20B in color.
Pistils are average in number for the class (about 30). Styles are uneven, short to average in length, of thin to average caliper, and are somewhat bunched. Stigma color is near Yellow-Orange 20B. Most ovaries are enclosed in the calyx and afew protrude from the calyx.
Hips are of average length, oblong in form and smooth, with thick, fleshy walls. Hips are near Orange-Red 31A in color.

The color of the upper surface of mature leaves is near Yellow-Green 147A. The under surface of the mature leaves is near Yellow-Green 147C in color. The upper surface of the young leaves is near Yellow-Green 147A in color, tinted with nearRed-Purple 59D. The under surface of young leaves is near Yellow-Green 147C in color, tinted with near Red-Purple 59D.
The rachis is average in size. Its upper side bears some stipitate glands on the edges. The underside is sparsly prickly.
