Abstract

A new hybrid grandiflora rose having the following combination of characteristics: a profusion of brightly colored, well-formed flowers; an abundance of leathery foliage which covers even the lowest branches; it is a vigorous, easy to grow and easy to care for plant having an upright habit and a highly branched bush which lends itself to usefulness for landscaping purposes.

Description

This invention relates to a new class of hybrid Grandiflora rose cv. "Shreveport". The plant is a hardy outdoor seedling of the bush type, cultivated for garden decoration. It was hybridized by Reimer Kordes in Sparrieshoop, Holstein, West Germany, by crossing "Zorina", U.S. Plant Pat. No. 2,321, as its seed parent, and "Uwe Seeler" as its pollen parent. The resulting seedling was asexually reproduced by budding. It holds its distinguishing characteristics through succeeding propagations by budding.
The new rose plant cv. Shreveport is particularly characterized by the following combination of characteristics: profusion of brightly-colored, well-formed flowers as described and illustrated herein; its abundance of leathery foliage and with foliage covering even the lowest branches thereby lending an overall attractiveness to the bush; its above average disease resistance in the Ontario, Calif. locale and its vigor providing an easy-care, easy-to-grow plant; and its upright habit and highly branched bush lend to its usefulness in the landscape.
This new cultivar may be distinguished from its seed parent, Zorina, by the following combination of characteristics:
Shreveport is classified as a hybrid Grandiflora, whereas seed parent (Zorina) is classed as a hybrid Floribunda.
Shreveport will only be utilized for garden decoration, whereas Zorina is used strictly as a variety for greenhouse cut rose production.
The seed parent, Zorina, bears flowers that are just under 3 inches in diameter whereas the flowers of the new cultivar (Shreveport) are significantly larger, of 31/2 to 41/2 inches in diameter.
The new rose Shreveport bears flowers of 44 to 51 petals, whereas Zorina bears flowers of significantly lower petalage (near 25).
The new cultivar rose (Shreveport) may be distinguished from its pollen parent (Uwe Seeler) by the following combination of characteristics:
Uwe Seeler bears flowers with 25 to 35 petals, whereas Shreveport bears flowers of significantly higher petalage (44 to 51) essentially as described and illustrated herein.
Whereas the new rose is classified as a hybrid Grandiflora, Uwe Seeler is classified as a hybrid Floribunda.
Whereas Uwe Seeler bears flowers of moderate fragrance, the new rose Shreveport bears flowers with only a slight tea fragrance.
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 in London, England.
FLOWER
The new variety usually bears its flowers singly, sometimes three or more flowers per stem and in regular, flat clusters on strong, medium-length stems. Outdoors, the plant blooms almost continuously and gives abundant quantities during the growing season. It has a slight tea fragrance.
BUD
The peduncle is of short to average length, and average caliper, erect and stiff. It is moderately smooth with some stipitate glands; and it is between Yellow-Green 147A and Green 137A in color.
Before the calyx breaks, the bud is medium in size, and is of medium length, ovoid to globular in form, with foliaceous appendages and some stipitate glands on the surface of the bud. There are usually slender foliaceous parts extending beyond the tip of the bud equal to one-half or more of its length.
As the calyx breaks, the color is near Orange-Red, 32C.
The inner surfaces of the sepals have a fine, wooly tomentum; margins are lined with stipitate glands.
As the first petal opens, the bud is average in size and of medium length, ovoid to globular in form. The color on the outside of the basal attachment zone is near Yellow, 12B and suffuses to between Orange-Red, 32C and 32D. The inside surface shows a defined basal attachment zone of near Yellow, 12B that changes abruptly to between Orange-Red, 32C and 32D. The bud opens up well and is not retarded or prevented from opening by hot, wet or dry weather.
BLOOM
The size of the bloom when fully open is average in size, ranging from 31/2 to 41/2 inches. The petalage is very double, with from 44 to 51 petals and from 2 to 7 petaloids, arranged regularly. The bloom is very globular at first, becoming cupped. At first the petals remain tightly cupped, with tips reflexed slightly outward, becoming later at maturity loosely cupped with tips reflexed outward.
The petals are thick and with the inside slightly satiny and the outside slightly shiny. The outside petals are round to broadly obovate with a flat apex. The intermediate petals are broadly obovate and with a rounded to flat apex. The inside petals narrowly obovate with the apex having one or two notches. The colors may be modified by being bordered or margined or blotched, shaded and/or washed or tinted with other colors.
The paragraphs immediately following describe the color values observed in a flower newly opened in the month of August. The plant had been grown outdoors in Ontario, Calif.
The outside surface of the basal attachment zone is near Yellow, 12B and suffuses to between Orange-Red, 32D and Yellow-Orange 23C. The inner surface shows a defined basal attachment zone of near Yellow, 12A and changes abruptly to between Orange-Red 32C and 31C with edges exposed to sunlight occasionally blushing to deepening Orange-Red, 34C and 34A.
The outer surface and inner surfaces of the intermediate petals were the same as the outer and inner surfaces described above but with less of the intensified shadings at the petal edges. The outer and inner surfaces of the inner petals were as described above but without the deeper shading at the petal edges.
The paragraph immediately following describes color values observed in a bloom which had been open for three days, outdoors, in the month of August. The plant had been grown outdoors in Ontario, Calif.
The outer surface outside petal shows a basal attachment zone of near Yellow-Orange, 14C and suffuses to between Orange, 29B and 25B. The inner surface of the outside petal shows a basal attachment zone of near Yellow, 12B that abruptly changes to between Orange, 28C and Orange-Red 32D; occasionally areas near the edges exposed to sunlight blush to between Red, 41C and Orange-Red, 35B. The outer and inner surfaces of the inside petals are as described above for the outer and inner surfaces respectively of the outside petals.
The general color effect of the newly opened flower is between Orange-Red, 32C and 31C. The bloom after being three days open gives a general color effect which is near Orange-Red, 32D with occasional darker shadings near Red, 41C. The petals drop off cleanly and are not particularly affected by cold, hot, wet or dry weather.
In August, roses grown in the garden last on the bush from 4 to 5 days. Cut roses grown outdoors and kept at living-room temperatures will last from 3 to 5 days in the month of August.
