Abstract

A distinctive cultivar of Saintpaulia plant named `Dusk`, characterized by its compact plant habit; moderate growth rate; durable foliage; large light purple frilled flowers; and numerous long-lasting flowers.

Description

The present invention relates to a new and distinct cultivar of Saintpaulia or African Violet, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name `Dusk`. It is anticipated that the plant of this application will be marketed under the Trademark "Ultra Violet". Accordingly, the plant of this application may be referred to as "Ultra Violet" `Dusk` in the market place.
The new cultivar is a product of a planned breeding program conducted by the inventor in Oberlin, Ohio. The objective of the breeding program was to develop compact and durable Saintpaulia varieties with numerous, upright, long-lasting flowers and uniform flowering.
The new cultivar originated from a cross made by the inventor of the Saintpaulia cultivar `New Orleans` (disclosed in U.S. Plant Pat. No. 5,627) with violet flowers, as the male or pollen parent, with the Saintpaulia cultivar `Laser` (not patented) with pink frilled flowers, as the female or seed parent. The cultivar `Dusk` was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Oberlin, Ohio.
In side-by-side comparisons in Oberlin, Ohio, under commercial practice, plants of the new Saintpaulia differed in flower color, were more compact in habit, had shorter and stronger petioles and peduncles, and had smoother foliage than either parent cultivar.
Asexual reproduction of the new cultivar by leaf cuttings taken at Oberlin, Ohio, has shown that the unique features of this new Saintpaulia plant are stable and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Dusk`. These characteristics in combination distinguish the new Saintpaulia plant as a new and distinct cultivar:
1. Compact plant habit.
2. Moderate growth rate.
3. Durable foliage.
4. Large light purple frilled flowers that are held upright.
5. Numerous long-lasting flowers.
The new Saintpaulia plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Foliage and flower colors in the photograph may appear different from the actual colors due to light reflectance. The photograph comprises a top perspective view of a typical potted plant of `Dusk`.
The following observations, measurements, values, and comparisons describe plants grown in Oberlin, Ohio, under a double layer of polyethylene covering with average day and night temperatures of 21C and an average light level of 1,500 foot-candles.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
