A new, hardy hybrid miniature rose especially suited for garden decoration. The new cultivar bears large, multicolored flowers held well above the foliage in regular, rounded clusters. Flower petals are dropped cleanly before they can age to an unattractive off-color. The new variety is easy to grow, producing an abundance of large, vigorously growing deep-green foliage which covers the plant attractively. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the hybrid miniature class, essentially as herein illustrated and described, being particularly characterized by its rounded, compacthabit; its abundant production of large, multicolored flowers held well above the foliage; its abundant, large deep-green foliage that attractively covers the plant; its ability to drop old petals cleanly before they can age to an unattractiveoff-color; and its vigorous growth. |
| Description: |
This invention relates to a new variety of hybrid miniature rose plant cv. Aroyumi. The plant is a hardy outdoor seedling of the miniature bush type,cultivated for garden decoration. It was first discovered and asexually reproduced by Jack E. Christensen in Ontario, Calif., having as its seed parent Golden Angel (U.S. Plant Pat. No. 4,028) and as its pollen parent Cricket (U.S. Plant Pat. No.4,663).
The new rose cv. Aroyumi is particularly distinguishable from other presently commercialized rose cultivars by the following combination of characteristics: is rounded, compact habit; is abundant production of large, multicolored flowers heldwell above the foliage; its abundant, large deep-green foliage that attractively covers the plant; its ability to drop old petals cleanly before they can age to an unattractive off-color; and its vigorous growth, which makes the plant easy to grow. Aroyumi holds these distinguishing characteristics through succeeding propagations by cuttings and budding.
This new rose cultivar may be distinguished from its seed parent, Golden Angel (U.S. Plant Pat. No. 4,028), by the following combination of characteristics: Golden Angel produces flowers of a relatively uniform yellow color, whereas the newrose produces flowers that begin as yellow but blush to pinkish red, essentially as described and illustrated herein. Aroyumi bears flowers with 18 to 25 petals, whereas the seed parent produces flowers with significantly heavier petalage (60 to 70petals). Whereas the new rose bears flowers of 11/2 to 2 inches in diameter, Golden Angel bears significantly smaller flowers of 1 to 11/2 inches in diameter.
Aroyumi may be distinguished from its pollen parent, Cricket (U.S. Plant Pat. No. 4,663), by the following combination of characteristics: Cricket produces flowers of a relatively uniform, bright orange coloration, whereas the new cultivarproduces flowers of a yellow coloration blushing to pinkish red, essentially as described and illustrated herein. Aroyumi bears flowers of 11/2 to 2 inches in diameter, whereas the pollen parent bears significantly smaller flowers of 1 to 11/2 inches indiameter. Whereas the new rose produces a mature bush of a medium-low, compact habit with medium-caliper canes, Cricket produces a mature bush of a medium-tall, less compact habit with larger caliper canes.
The accompanying drawing illustratesthe new variety in color as grown in Ontario, Calif., 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 isaptly descriptive. Color names beginning with a capital letter designate values based on the R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.
The descriptive matter which follows pertains to roses grown in Ontario, Calif. and is believed to apply to similar conditions of soil and climate elsewhere.
FLOWER
The new variety bears its flowers sometimes singly, usually 2 to 3 flowers or more per stem, in regular, rounded clusters on stems of normal strength and of short to medium length for the class. Outdoors, the plant blooms very abundantly andnearly continuously throughout the growing season. The flowers have a slight fruity fragrance.
BUD
The peduncle is short to average in length for the class, of average to heavy caliper, strong, erect, and stiff. It is moderately rough with numerous stipitate glands and is between Yellow-Green 147A and Green 137C in color.
Before the calyx breaks, the bud is medium to large in size for the class, of medium length, and pointed to ovoid to globular in form. There are few foliaceous appendages and stipitate glands on the surface of the bud. There are usually slenderfoliaceous parts present which extend beyond the tip of the bud, equal to one quarter or more of its length.
As the calyx breaks, bud color is between Yellow-Orange 15B and Yellow 13B; areas exposed to sunlight blush to as deeply as between Red 42A and Red 45C. The inner surface of the sepals is lined with a fine woolly tomentum; sepal margins arelined with stipitate glands.
As the first petal opens, the bud is average to large in size for the class, of medium length, and pointed to ovoid to globular in form. The color of the outside petal surface is between Yellow-Orange 15B and Yellow 13B; areas exposed tosunlight blush to as deeply as between Red 42A and Red 45C. The color of the inside petal surface is the same as the outside surface with little blushing. 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 to large for the class, ranging from 11/2 to 2 inches in diameter. Petalage is double with the petals arranged regularly; petals number from 18 to 25, and there may be from 1 to 3 petaloidspresent. Bloom form when half open is moderately high-centered to cupped to globular, with petals moderately cupped and with petal edges moderately reflexed to rolled outward. When fully open, the bloom is cupped, with petals more loosely cupped andpetal edges very rolled to quilled outward.
Petals are of moderately heavy substance and of medium thickness, slightly satiny inside and slightly shiny outside. The outside petals are broadly obovate with rounded apices. Intermediate petals are nearly obovate with rounded apices. Insidepetals are narrowly obovate to irregular with rounded apices. Colors of all petals may be modified by being bordered or margined or blotched or shaded or washed or tinted 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 Ontario, Calif., during the month of November.
The outside surface of the outside petals is between Yellow-Orange 15C and Yellow 13B in color; areas exposed to sunlight blush to as deeply as between Red 42C and Red 45D. The inside surface of the outside petals is between Yellow-Orange 15Cand Yellow 13B in color; areas exposed to sunlight blush to as deeply as between Orange-Red 32C and Red 41C. The outside surface of the intermediate petals has the same color as the outside surface of the outside petals with less blushing. The insidesurface of the intermediate petals has the same color as the inside surface of the outside petals with less blushing. The outside surface of the inner petals has the same color as the outside surface of the outside petals with little or no blushing. The inside surface of the inner petals has the same color as the inside surface of the outside petals with little or no blushing.
The following paragraph describes the color values observed in a flower from a plant grown outdoors in Ontario, Calif., that had been open for three days in the month of November.
The outside surface of the outside and inside petals is between Yellow 12B and Yellow 9C in color. The inside surface of the outside and inside petals has the same color as the outside surface of the outside and inside petals, the majority ofthe petal surface having blushed to between Red 47C and Red 47A.
The general color effect of the newly opened flower is predominantly between Yellow-Orange 15C and Yellow 13B, with the outer petals blushing to between Orange-Red 32C and Red 41C. Three days after opening, the general color effect of the floweris predominantly between Red 47A and Red 47C, with some yellow tones toward the flower center between Yellow 12B and Yellow 9C.
Petals usually drop off cleanly and are not particularly affected in this respect by cold, hot, wet, or dry weather. Flowers last on the bush in the garden from 4 to 5 days during the month of November in Ontario, Calif. Flowers cut from plantsgrown outdoors in the month of November last from 4 to 5 days at living-room temperatures.
