| Abstract: |
An African Violet referred to by the cultivar name Nashville having compact and vigorous growth habits; red-purple, frilled, non-dropping flowers; strong and upright stems; relatively quick saleability due to its vigorous growth habit, and by its generally funnel-shaped leaves having light-green centers. |
| Claim: |
I claim:
1. A new and distinct cultivar of African Violet, as described and illustrated, referred to by the cultivar name Nashville and particularly characterized by the combined features ofcompact and vigorous growth habits; red-purple, frilled, non-dropping flowers; strong and upright stems; relatively quick saleability due to its vigorous growth habit, and by its generally funnel-shaped leaves having light-green centers. |
| 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 Nashville. The newcultivar was identified during the breeding and selection process by the designation d. 150/2 - 67/78.
Nashville is generally characterized by a very compact habit, leaves which are light green at the center and slightly wavy and serrated at the edges. Leaves with light green centers are commonly referred to as "girl" type leaves. The flowersare red-purple frilled, and are carried on strong upright stems. These traits in combination were not present in previously available commercial cultivars.
The new cultivar was originated from a cross made in a controlled breeding program in Isselburg, Rhineland, Germany. The female, or seed parent was 79 blue, a "girl" type cultivar of the type mentioned above. The male, or pollen parent was17/75, a blue-violet cultivar known by the cultivar name Evelyn and disclosed in U.S. Plant Pat. No. 4,154.
The new cultivar Nashville was discovered and selected as a flowering plant within the progeny of the stated cross by me in a controlled environment in Isselburg, Rhineland, Germany.
Asexual reproduction of the new cultivar by leaf cuttings and by division of shoots, as performed by me at Isselburg, Rhineland, Germany, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmlyfixed and are retained through successive generations of asexual reproduction.
The following observations, measurements and values describe plants grown in Isselburg, Rhineland, 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 Nashville, which in combination distinguish this African Violet as a new and distinct cultivar;
(1) Very compact habit.
(2) Red-purple, frilled edge flowers, non-dropping.
(3) Vigorous growth habit.
(4) Strong flower stems, with up to 8 flowers on each stem.
(5) Funnel-shaped leaves with light-green center.
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 thistype.
In the following description, color references are made to the Royal Horticultural Society (RHS) color chart, except where general color terms of ordinary significance are used.

General observations: Nashville is a vigorous growing variety. In a relative short growing period the plant is saleable with the first flash of flowers, a significant commercial factor. The habit is very compact and the flower stems are strongand upright. The flowers are frilled, red-purple, and non-dropping. The leaves with the light-green center are thicker than normal violet varieties.
