Abstract

An African violet plant known by the cultivar name Vermont having strong upright stems, with 10-12 flowers per stem, with the flowers being clear and deep blue, the cultivar flowers profusely, has a uniform growth habit, and lush medium green leaves.

Description

The present invention comprises a new and distinct cultivar of African violet plant, botanically known as Saintpaulia ionantha, and hereinafter referred to by the cultivar name Vermont.

The new cultivar was referred to during the breeding and selection process by the designation E 18/1, and is a product of a planned breeding program. The basic objective of the breeding program was to create a new African violet cultivar having single flower form, blue in color, and upright stems with a profuse flower head.

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 296 SAM blue. The male, or pollen parent was a cultivar designated FEDA blue upright.

The new cultivar Vermont 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 and by division of shoots, as performed by 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.

Vermont 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 and values 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 repeated observed and are determined to be basic characteristics of Vermont, which in combination distinguish this African violet as a new and distinct cultivar:

1. Vigorous growth habit.

2. Nine to fifteen strong upright flower stems.

3. Ten to twelve or more flowers per stem.

4. Clear and deep blue blossom color.

5. Profuse flowering.

6. Uniform in growth.

7. Lush medium green leaves.

8. Attractive saleable plant within 8-9 weeks after potting.

The accompanying photographic drawing shows a typical specimen plant of the new cultivar. 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., except where general colors of ordinary significance are referred to. Color values were taken under natural light conditions approximately mid-day in Isselburg, West Germany.
