Latest Green Circle Growers, Inc. Patents:
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 `Moonlight`. 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" `Moonlight` 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 two unnamed proprietary seedling selections. The cultivar `Moonlight` 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 had more compact growth habit, more uniform flowering and flowered earlier than either parent seedling selection.
Asexual reproduction of the new cultivar 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 characteristic of `Moonlight`. 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 dark green foliage.
4. Frilled purple and white bicolor 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 th new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage colors in the photograph may appear different than the actual colors due to light reflectance. The photograph comprises a top perspective view of a typical potted plant of `Moonlight`.
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 Horticulural Society Colour Chart except where general terms of ordinary dictionary significance are used.
