| Abstract: |
An African Violet known by the cultivar name Boston having strong upright stems carrying intensive pink flowers having frilled edges; compact and vigorous growth habit, and leaves which are cupped to form a flat funnel, with the leaves having serrated edges and light-green centers. |
| Claim: |
I claim:
1. A new and distinct cultivar of African Violet, as described and illustrated, known by the cultivar name Boston and characterized by the combined features of strong upright stemscarrying intensive pink flowers having frilled edges; compact and vigorous growth habit, and by its leaves which are cupped to form a flat funnel, with the leaves having serrated edges and 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 Boston.
The new cultivar, designated during the breeding and selection process as d. 150/1 and 47/78, is a product of a planned breeding program of the present inventor. Boston is principally characterized by its very intensive pink, frilled flowers;compact habit, and leaves which are light green in the center and upturned at the edges to form a generally flat funnel, with the leaf edges being serrated. The light green center characteristic of the leaves is commonly referred to in the industry as a"girl" type cultivar. 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, an unpatented "girl" type cultivar. The male, or pollen parent was 17/75, disclosed inU.S. Plant Pat. No. 4,154 and known by the cultivar name Evelyn.
The new cultivar Boston 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 Boston, which in combination distinguish this African Violet as a new and distinct cultivar:
(1) Strong, upright flower stems, with up to 10 flowers on each stem.
(2) Very compact habit
(3) Leaves are cupped to generally funnel shaped form with light green centers
(4) Leaf edges are serrated
(5) The underside of the leaf is reddish-green between the light green veins
(6) Very intense pink flower color, with the flowers having frilled eges.
(7) Vigorous growth habit
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 thefollowing description, color references are made to the Royal Horticultural Society (RHS) color chart, except for flower color, which is based on the Horticultural Colour Chart, Wilson (HCC), or where general color terms of ordinary significant are used.
