Abstract: A new variety of hybrid tea rose for greenhouse culture and commercial production of cut flowers distinguished by its continuous and abundant production of large cardinal red flowers on long, strong stems; and its long and attractively pointed buds which, when half opened, display a flower having a high pointed center with the inner petals provided with a very desirable swirling effect and having a tendency to individually unfurl until the flower is fully opened thereby displaying a center of many yellow stamens which enhances and accentuates the velvety iridescence of the redness in the opened flower. This new plant has a vigorous, much branched growth habit and a moderately abundant production of medium large leaves and of strong, large diameter canes.
Claim: I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized, in particular, by its free, abundant and continuous production of flowers borne onlong, strong stems and which have an improved vase life; its moderately abundant production of medium large leaves throughout the entire length of the stem; and by its vigorous and much branched growth habit.

My new red rose cultivar is the result of my breeding efforts carried on at Richmond, Ind., with the object of producing a more distinctive and classical bud and open flower with improved stem length, productivity, resistance, and vase life as acommercial cut flower. This seedling resulted from my crossing "Love Affair", U.S. Plant Pat. No. 3,287, and an unnamed and unpatented seedling which possessed excellence of stem, foliage, flower and disease resistance that was desired to be capturedin the new plant. This was successfully accomplished in the new seedling, as well as an improved color compared to that of the seed parent. This crossing was done in the Spring of 1976 and the first flowers appeared in the Fall of 1977. The beauty ofthis flower and the excellent characteristics of the plant led to my propagating the new plant for observation and test and this was done by budding at Richmond, Ind. Subsequent propagation by budding through successive generations has shown that thedesired and novel characteristics of this plant hold true from generation to generation and appear to be firmly fixed.


This new variety of rose plant is illustrated by the accompanying photographic drawing which shows, in full color, several stages of the bud opening, a newly opened flower, top and under side views of typical leaves, specimens of young and oldwood, and typical petals of a newly opened flower and of a three day opened flower, the colors shown being as nearly true as can be reasonably obtained by careful conventional photographic procedures.


The following is a description, in detail, of my new rose plant variety with color designations according to Koster's Color Guide (K), and the Robert S. Wilson Horticultural Colour Chart (W) issued by The British Colour Council in collaborationwith The Royal Horticultural Society of London, England, the following data being from observations of greenhouse plants grown at Richmond, Ind.

This new rose variety most nearly resembles the rose cultivar "Samantha" (U.S. Plant Pat. No. 3,727) inasmuch as the color of the flower is comparable; however, the foliage of this new variety is larger and more abundant and the new plant iseasier to time for cropping in the greenhouse under controlled environmental conditions.

With respect to its seed parent, my new rose cultivar has the advantage that the flower is borne on longer stems thereby requiring less pinching to produce desirable cut flower lengths for the commercial cut flower market. Also, the foliage ofthe new plant is leathery and abundant throughout the entire length of the stem and the flower color is more brilliant and does not tend to turn blue during living room temperature vase-life of six to seven days. Furthermore, the half-opened flower ofthis new plant has a high pointed center with the inner petals having a very desirable swirling effect and these inner petals have a tendency to individually unfurl progressively until the flower is fully opened to display a center of many yellow stamenswhich enhance and accentuate the velvety iridescence of the redness in the open flower.
