| Abstract: |
A hybrid tea rose variety having non-fragrant, double white blooms on a vigorous, slightly angular growing bush. |
| 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 vigorous, slightly angular plant habit, near white buds opening into non-fragrant, double white blooms. |
| Description: |
This present invention relates to a new and distinct variety of rose plant of thehybrid tea class, which was originated by me by crossing the variety Tonight, U.S. Plant Pat. 3,522, with pollen of the variety Coral Satin, U.S. Plant Pat. No. 2,098.
The purpose of this type of breeding, a red hybrid tea with pollen of a coral pink climbing variety, was exploratory in that no prediction could be made as to the type of progeny expected. This particular selection from the seedlings of thiscross is a bush type hybrid tea bearing white flowers.
This variety is new and unique as evidenced by the following combination of characteristics which are outstanding and which distinguish it from its parents as well as from all other varieties of which I am aware:
1. A vigorous, well branched, slightly angular habit of growth.
2. Reddish purple new foliage.
3. Nearly white buds, tinted slightly, especially near the petal tips, with pink.
4. A fully double, over 40 petals, open flower of near white.
5. Open flower form is such that outer petals are positioned straight out (90.degree.) from the stem axis; and center petals cover the reproductive parts of the flower.
6. Little or no 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.
The accompanying 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 colorillustrations of this character.
The following is a detailed description of my new rose cultivar with color in terminology in accordance with the Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color isindicated.
