Hybrid tea rose plant named `Hawaiian Queen Martha`

Abstract

A hybrid tea class rose plant with many fine attributes for the home gardener and the exhibitionist: unusual salmon-pink petal coloration, long lasting on bush or as a cut flower; 24 to 30 inch cutting stems and a pleasant, moderately strong fragrance.

Description

This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing the variety Kordes Perfecta (U.S. Plant Pat. No. 1,604) (seed parent) with the variety Dothan (pollen parent).

The primary objective of this breeding was to produce a new rose variety which had an unusual and distinctive color combination, along with good foliage and long stems. As both parent roses had much color variation in their breeding, I felt that the cross could produce favorable results. My objective was substantially achieved as evidenced by the following combination of characteristics which distinguish it from its parents as well as from all other varieties of which I am aware, and make it an excellent garden and exhibition type rose:

1. Long cutting stems, 24 to 30 inches.

2. Unusual salmon-pink petal coloration.

3. Moderately strong fragrance.

4. 55 to 60 petals with much substance; long lasting on bush or as a cut flower.

Asexual reproduction by budding, performed in the Hilo, Hi., area, shows that all characteristics and distinctions come true to form and are transmitted through succeeding propagations.

The accompanying photographic illustrations show typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to attain in color illustrations of this character.

FIG. 1 shows the flower buds in varying stages of opening, foliage and flowering stems.

FIG. 2 further illustrates the bloom, stem, and foliage.

FIG. 3 shows a flower about 25-33% open.

FIG. 4 shows a flower about 80-85% open.

FIG. 5 further illustrates foliage.

The following is a detailed description of my new rose cultivar with color terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
