| Abstract: |
A new and distinct cultivar of African violet named Van Gogh, as described and illustrated, and particularly characterized by its single violet-shaped multi-colored flowers with unique markings of large white centers contrasting with the dark lilac petals; strong, upright flower stems that curve slightly toward the center to form a compact bouquet above the leaves; medium green, heart-shaped leaves; profuse flowering; vigorous and compact growth habit; flowering 9-10 weeks after potting, and by its long lasting and non-dropping flowers. |

I claim:
1. A new and distinct cultivar of African violet plant named Van Gogh, as described and illustrated, and particularly characterized by its single violet-shaped multi-colored flowers withunique markings of large white centers contrasting with the dark lilac petals; strong, upright flower stems that curve slightly toward the center to form a compact bouquet above the leaves; medium green, heart-shaped leaves; profuse flowering; vigorous and compact growth habit; flowering 9-10 weeks after potting, and by its long lasting and non-dropping flowers. |
| Description: |
The present invention comprises a new and distinct cultivar of Africanviolet plant, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name Van Gogh.
The new cultivar was referred to during the breeding and selection process by the designation 1062/22 and is a product of a planned breeding program. The new cultivar was originated from a cross made by me in the controlled breeding program inHaffen, Federal Republic of Germany. The female, or seed parent was a cultivar designated 726. The male, or pollen parent was a cultivar designated 1062.
Van Gogh was discovered and selected by me as a flowering plant within the progeny of the stated cross in a controlled environment in Haffen, West Germany. A sexual reproduction of the new cultivar by leaf cuttings, as performed by me at Haffen,West Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.
Van Gogh 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 Haffen, West Germany and Nashville, Tenn. under greenhouse conditions which closely approximate those generally used in commercial pratice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Van Gogh, which in combination distinguish this African violet as a new and distinct cultivar:
1) Strong, upright flower stems curving slightly toward the center.
2) Single violet-shaped multi-colored flowers with large white centers and dark lilac petals.
3) Profuse flowering.
4) Each plant carries 8-10 and more upright flower stems each of which carries 8-10 and more flowers.
5) Long lasting, non-dropping flowers.
6) Vigorous and compact grower.
7) Plant saleable 9 to 10 weeks after potting.
8) Seed capsules push slightly through.
9) Medium green, heart-shaped through. 10) After maturity the flowers dry off, and remain on the peduncle without becoming infected by botrytis.
The new cultivar is most similar to Monet, for which a U.S. plant patent is also in the process of being applied for. Both cultivars have the same unique bi-colored designs on the blossoms with a large white center and another color on thepetals. However, Monet has purplish blue petals whereas Van Gogh has dark lilac and somewhat larger petals.
The accompanying color photographic drawing shows a typical specimen plant of the new cultivar. The colors appearing in the photographare as true as possible with color illustrations of this type.
In the following description, color references are made to The Royal Horticultural Society Color Chart (R.H.S.), except where general colors of ordinary significance are referred to. Color values were taken under natural sunlight conditions at approximately 12 p.m. in Nashville, Tenn.
Botanical classification: Saintpaulia ionantha, Ramat., c.v. Van Gogh.
Parentage:
Male parent.--1062.
Female parent.--726.
Propagation: The new cultivar holds its distinguishing characteristics through successive propagations by leaf cuttings.
Plant: From 8 cm to 10 cm tall when grown in pots, and 24-27 cm in diameter when fully grown.
Leaves.--General form: Heart-shaped. Diameter: 55-65 mm wide and 60-70 mm long. Texture: Velvety. Aspect: Hairy, slightly shiny. Veins: Upperside: visible: underside: well pronounced, light green, shiny. Color (upperside): BetweenYellow-green group 147 A and 146 A. Color (underside): Greyed-green group 194 D with patches of greyed-purple group 186 C to D. Petiole: Strong, light geen, hairy.
Flowers.--Buds: Bell-shaped, dark lilac, 5-7 mm just before opening. Sepals: Five (5). Color: Green with purplish brown touch. Calyx: Shape: Funnel-shaped. Aspect: Spear-shaped, hairy. Peduncle: Character: Strong upright, hairy. Color:Green, occasionally brownish touch.
Individual flowers.--Size: 40-45 mm. Shape: Single violet-shaped with wavy petal tips. Color (upperside): White center with purple-violet Group 81 A to B on petals. Under cooler temperatures and more intensive lighting, the lilac tends tointensify. Color (underside): White center with purple-violet Group 81 C on petals. Borne: Each flower stem carries 8-10 and more flowers on strong, upright peduncles that are free standing above the leaves, thereby forming a compact bouquet. Flowering habit: Flowers 9-10 weeks after potting.
Reproductive organs.--Stamens: Two (2). Anthers: 2 composed of 4 anther cells, seed capsules push slightly through. Filaments: Yellowish white, 3-4 mm long. Pollen color: Yellow group 7 A. Styles: 7-8 mm long, dark lilac, base of ovary lightgreen and hairy.
Roots.--Normally developed, white when young, turning slightly brownish when older.
Disease resistance: Up to date, Van Gogh has shown very good resistance to all major violet diseases.
General Observations
Van Gogh is an attractive cultivar due to its multi-colored flowers which have unique markings of large white centers contrasting with the dark lilac petals. The amount of dark lilac spread may vary just slightly from one blossom to another. Atight bouquet of flowers free standing above the leaves develops 9-10 weeks after potting. Each of the 8-10 and more strong flower stems carries 8-10 and more single violet-shaped flowers with slightly wavy petal tips. Medium green, heart-shaped leavessurround the flower bouquet. The flowers are long-lasting and non-dropping and the seed capsules push slightly through.
