| Abstract: |
An African violet known by the cultivar name Alberta, having a vigorous growth habit; 12 or more strong flower stems each of which carries 12 or more violet-shaped flowers which are generally white with purple centers and edges, with the flowers normally containing five petals, with an occasional small petal appearing at the center attached to the receptacle; uniform bouquet and by its long blooming period. |
| Claim: |
I claim:
1. A new and distinct cultivar of African violet, as shown and described, known by the cultivar name Alberta, and characterized by the combined features of vigorous growth habit; producing 12 or more strong flower stems each of which carries 12 or more violet-shaped flowers which are generally white with purple centers and edges, with the flowers normally containing five petals, with an occasional small petal appearing at thecenter attached to the receptacle; uniform bouquet and by its long blooming period. |
| Description: |
The present invention comprises a new and distinct cultivar of African violet plant, botanically known asSaintpaulia ionantha, and hereinafter referred to by the cultivar name Alberta.
The new cultivar was referred to during the breeding and selection process by the designation C 44/1-98/79, and is a product of a planned breeding program. Alberta is generally characterized by generally violet-shaped flowers, strong flowerstems, uniform bouquet, prolonged blooming with non-dropping flowers, and up to 12 and more flowers per stem. The flowers are generally white, with purple tinging on the edges and centers. These traits in combination were not present in previouslyavailable 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 a cultivar designated Velli/Wifo blue, unpatented. The male, or pollen parent was a cultivardesignated 86/75 white star, also unpatented.
The new cultivar Alberta 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, meausurements and values described plants grown in Isselburg, Rhineland, Germany, under greenhouse conditions which closely approximate thosegenerally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Alberta, which in combination distinguish this African violet as a new and distinct cultivar:
(1) Upright and strong flower stems.
(2) Up to 12 or more violet-shaped flowers per stem.
(3) The base color of the flowers is white, with the center and edges being red-violet.
(4) Vigorous growth habit, producing 12 or more flower stems.
(5) Flexible leaves and petioles.
(6) Long blooming period.
(7) The petals are normally five in number, three large and two small, although occasionally an additional small petal will appear at the receptacle.
The accompanying photographic drawing shows a typical specimen plant of the newcultivar. 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 Royal Horticultural Society color chart (RHS), except where generalcolor terms of ordinary significance are used.
