The present invention comprises a new and distinct cultivar of New Guinea Impatiens, referred to by the cultivar name `Claramarie`.
`Claramarie` is a product of a planned breeding program and was originated from a hybridization made by the inventor Norbert Bull in a controlled breeding program in Goennebek, Germany, in 1989. The female parent was a seedling designated no. 51 and the male parent was a seedling designated no. 50. Both parents are proprietary cultivars used in the breeding program.
`Claramarie` was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in 1989 in a controlled environment in Goennebek, Germany.
The first act of vegetative or asexual reproduction of `Claramarie` was accomplished when cuttings were taken from the initial selection in 1990 in a controlled environment in Goennebek, by, or under the supervision of, Norbert Bull.
Horticultural examination of plants grown from cuttings of the clone initiated in Spring 1991 in Goennebek, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for `Claramarie` are firmly fixed and are retained through successive generations of asexual reproduction.
`Claramarie` 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, without, however, any variation in genotype.
The following observations, measurements, and comparisons describe plants grown in Hillscheid, Federal Republic of Germany under greenhouse conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of `Claramarie` which in combination distinguish this Impatiens as a new and distinct cultivar:
1. Pure white flower color.
2. Large, round flowers.
3. Medium green foliage without variegation.
4. Medium plant habit.
5. Early to medium flower response.
Of the many commercial cultivars known to the present inventor, the most similar in comparison to `Claramarie` is the cultivar `Jasius`, disclosed in U.S. Plant Pat. No. 7,345. In comparison to `Jasius`, `Claramarie` has somewhat lighter green foliage, smaller leaves, and a shorter plant habit.
The accompanying photographic drawing shows typical flower and foliage characteristics of `Claramarie` with colors being as true as possible with illustrations of this type. In this regard, the illustration does not accurately depict the true color of the cultivar's eye zone area as it is described in the botanical description.
In the following description color references are made to The Royal Horticultural Society Colour Chart.
The color values were determined indoors from flowers taken from plants grown in Hillscheid, Federal Republic of Germany, under greenhouse conditions which approximate those generally used in commercial practice. The description is based on plants which were planted as rooted cuttings in 10 cm pots and grown at 20°C minimum temperature.
