Rose plant--Dolly Parton variety

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which continually bears very large attractive fully double rich orange-red blossoms on strong sturdy stems. Such robust blossoms further can be characterized by their distinctive outstanding fragrance which is heady and somewhat fruity in nature. Accordingly, the present variety can be relied upon to give a colorful and fragrant garden display from spring to the first frost of fall. The new variety resulted from the crossing of the Fragrant Cloud variety (U.S. Plant Pat. No. 2,574) and the Oklahoma variety (U.S. Plant Pat. No. 2,326).

Description

SUMMARY OF THE INVENTION

The new and distinct variety of Hybrid Tea rose plant of the present invention was created by artificial pollination wherein two parents were crossed which previously had been studied for the possible possession of the characteristics sought in the new variety. The parents of the new variety were the Fragrant Cloud variety (U.S. Plant Pat. No. 2,574) and the Oklahoma variety (U.S. Plant Pat. No. 2,326).

Seeds from the artificial pollination were sown, and the resulting seedlings were observed. Selective study resulted in the identification of a single plant of the new variety. The desirable qualities of the new variety have been confirmed through extensive testing and the importance of the new variety has been firmly established.

It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following characteristics:

(a) forms attractive very large fully double blossoms of orange-red coloration,

(b) exhibits an outstanding blossom fragrance,

(c) exhibits excellent blossom form,

(d) forms strong sturdy stems,

(e) exhibits exceptional vigor which creates a well-branched broad and upright plant, and

(f) exhibits above average disease resistance.

The orange-red blossoms are generally without blemish or streaking. Only under the hot summer sun do the outer edges of the petals show any color change as they take on a rich red shade. As the blossoms open, the outer petals gently roll back while the inner petals tend to hold to give a high-centered bloom that almost always hides the center. Eventually the petals will open out to form an attractive cup-shaped very double flower. The new variety tends to blossom continually and can be considered to be ever-blooming. The fragrance of the blossoms is exceptional and is exhibited from the time the first petal unfurls until the last petal drops. Such fragrance is heady and somewhat fruity in nature.

In view of these characteristics the new variety meets the needs of the horticultural industry for all purposes, and is particularly well suited for growing by the home gardener as a flowering shrub whose well-formed, highly fragrant blossoms are ideal for cutting and exhibiting.

The new variety has been found to readily undergo propagation by budding and by cuttings. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation.

The new variety has been named the DOLLY PARTON variety.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is possible to make the same in a color illustration of this character, typical specimens of plant parts obtained from plants of the new variety grown in the field at West Grove, Pa.

In the upper left portion of the photograph young foliage is shown. At the upper right a segment of a strong sturdy stem which is typical of the new variety is shown. At the upper left center of the photograph buds of the new variety in two stages of opening are shown. Across the left and center of the photograph three attractive very large fully double blossoms of the new variety are shown in various stages of opening.

DETAILED DESCRIPTION
