| Abstract: |
An African violet named Texas, particularly characterized by its vigorous and very uniform growth habit, dark green, shiny leaves, upright stems each of which carries 7-12 flowers, and by its large blue frilled flowers which are long lasting and non-dropping. |
| Claim: |
I claim:
1. A new and distinct cultivar of African violet known by the cultivar name Texas, as described and illustrated, and particularly characterized by its vigorous and very uniform growthhabit, dark green, shiny leaves, upright stems each of which carries 7-12 flowers, and by its large blue frilled flowers which are long lasting and non-dropping. |
| Description: |
The present invention comprisesa new and distinct cultivar of African violet plant, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name Texas.
The new cultivar was referred to during the breeding and selection process by the designation D102/2, and is a product of a planned breeding program. The basic objective of the breeding program was to create a new African violet cultivar havingrelatively large blue frilled blossoms.
The new cultivar was originated from a cross made in a controlled breeding program in Isselburg, West Germany. The female, or seed parent was a cultivar designated b. 36/1, blue frilled. The male, or pollen parent was Wisconsin, disclosed in myU.S. Plant Pat. No. 4,353.
The new cultivar Texas was discovered and selected by me as a flowering plant within the progeny of the stated cross in a controlled environment in Isselburg, West Germany. Asexual reproduction of the new cultivar by leaf cuttings, as performedby me at Isselburg, West Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.
Texas has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length. The following observations, measurements andvalues describe the new cultivar as grown in Isselburg, West Germany, under greenhouse conditions which closely approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Texas, which in combination distinguish this African violet as a new and distinct cultivar:
1. Vigorous and very uniform growth habit.
2. Upright, wire-like stems, approximately 9 in number, each of which carries 7-12 flowers.
3. Large blossoms, blue in color and having frilled edges.
4. Flexible petioles.
5. Relatively dark green leaves.
6. Attractive saleable plant with compact and rich flower head within 10 weeks after potting.
The new cultivar is distinguished from Wisconsin by its more vigorous growth, frilled flowers, more profuse flowering, and by its large flower diameter.
The accompanying photographic drawing shows a typical specimen plant of the newcultivar. The colors appearing in the photograph are as true as possible with color illustrations of this type.
In the following description, color references are made to the Horticultural Colour Chart (HCC) issued by Wilson Colour Ltd., exceptwhere general colors of ordinary significance are referred to. Color values were taken under natural light conditions approximately mid-day in Isselburg, West Germany.
