| Abstract: |
A hybrid tea rose plant having unique pale yellow bud that fades to white on the outer petals as the flower opens, dark green leathery glossy foliage, resistance to mildew and rust, thick leathery petals, excellent exhibition bud form and sweet pleasant fragrance. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofits novel light yellow fading to white on the outer petals flower color, its dark green leathery and disease resistant foliage, its thick leathery petals, its excellent exhibition flower form and its sweet pleasant fragrance. |
| Description: |
The 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 Pristine, U.S. Plant Pat. No. 3,997, with the varietyAntigua, U.S. Plant Pat. No. 3,431.
The primary objective of this breeding was to produce a new rose variety having the flower form of Pristine combined with the excellent foliage and higher petal count of Antigua. It was also hoped to create a flower color somewhere betweenPristine and Antigua. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from itsparents, as well as from all other varieties of which I am aware:
1. Unique pale yellow bud that fades to white on the outer petals as the flower opens.
2. Dark green leathery glossy foliage.
3. Resistance to mildew and rust.
4. Thick leathery petals.
5. Excellent exhibition bud form.
6. Sweet pleasant fragrance.
Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
Theaccompanying illustration shows 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 make the same in a color illustration of thischaracter.
The following is a detailed description of my new rose cultivar with color description using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of coloris indicated.
