| Abstract: |
A novel hybrid tea rose cultivar characterized by a vigorous, upright growth habit, white blossoms, and resistance to powdery mildew. |
| Claim: |
I claim:
1. A new and distinct cultivar of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of avigorous upright habit of growth, Garnette Brown new foliage maturing to dark green, nearly white buds with a tint of Egyptian Buff and tipped with Carmine, opening to white blooms of 18 to 25 petals, large prickles angled slightly downward and a lightfragrance. |
| Description: |
The present invention relates to a new and distinct cultivar of rose plant of the hybrid tea class which was originated by me by crossing two unnamed cultivars of roses.
The primary objective of this breeding was to produce a hybrid tea cultivar of vigorous, upright growth with the possibility that the color would be white, coral, pink or yellow and the flowers large and plentiful. The objective was fullyachieved in this white flowered cultivar, as evidenced by the following unique combination of characteristics which are outstanding in this new cultivar and which distinguish it from its parents as well as from all other cultivars of which I am aware:
1. A vigorous, upright habit of growth.
2. Garnette Brown new foliage developing into dark green mature foliage, quite resistant to rose powdery mildew.
3. Buds of a very light tint of Egyptian Buff (W) with the tip edged Carmine (W).
4. Partly open to open flowers white with 18 to 25 petals.
5. Large prickles slightly hooked downward.
6. Very slight fragrance.
Asexual reproduction of this new cultivar 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 cultivar 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 terminology in accordance with Wilson's Horticultural Color Chart, except where ordinary dictionary significance of color is indicated.
