Abstract

An African violet plant having vigorous and compact growth habit; intensive blue-violet flowers carried on 7-9 flower stems, with up to 12 or more flowers per stem; attractive dark green, shiny leaves, and by its long lasting and non-dropping flowers.

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 Michelle. The new cultivar was referred to during the breeding and selection process by the designation XXI/16-3/79, and is a product of a planned breeding program. The new cultivar is generally characterized by a rich abundance of blue-violet flowers carried by strong upright stems well above the leaves. There are 7-9 flower stems at full flowering, each carrying 7-12 single flowers, thereby providing a full and right bouquet. 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 a cultivar designated 26 AN/Z blue-violet, single, an unpatented variety. The male or pollen parent was a cultivar designated B 229/11 pink single, also unpatented.

The new cultivar Michelle 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 firmly fixed 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 the new cultivar, Michelle, which in combination distinguish this African violet as a new and distinct cultivar:

(1) Vigorous growth habit.

(2) Attractive dark green, shiny leaves.

(3) 7-9 flower stems, strong and upright, with 12 or more single flowers on short peduncles.

(4Intensive violet-purple flower color.

(5) Flowers do not fade when maturing, and do not drop.

(6) Very long lasting flowers.

(7) Compact 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 the following description, color references are made both to the Royal Horticultural Society color chart (RHS) and the Horticultural Color CHART (HCC) issued by Wilson Colour Ltd., except where general color terms of ordinary significance are obvious.
