The present invention comprises a new and distinict cultivar of New Guinea Impatiens, referred to by the cultivar name `Jennifer`.
`Jennifer` is a product of a planned breeding program and was orginated from a hybridization made by the inventor Norbert Bull in a contrtolled breeding program in Goennebek, Germany, in 1993. The female parent was a seedling designated no. 1 and the male parent was a seedling designated no. 5. Both parents are proprietary cultivars used in the breeding program.
`Jennifer` was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in 1994 in a controlled environment in Goennebek, Germany.
The first act of vegetative or asexual reproduction of `Jennifer` was accomplished when cuttings were taken from the initial selection in Autumn 1994 in a controlled environment in Goennebek by, or under the supervision of, Norbert Bull.
Horticultural examination of plants grown from these cuttings initiated in Spring 1995 in Goennebek, Germany, and continuing thereafter. has demonstrated that the combination of characteristics as herein disclosed for `Jennifer` are firmly fixed and are retained through successive generations of a sexual reproduction.
`Jennifer` 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 `Jennifer`, which in combination distinguish this impatiens as a new and distinct cultivar:
1. Light violet flower color
2. Numerous medium sized flowers
3. Light to medium green foliage
4. Narrow elliptical shaped leaves
5. Small plant habit, weak growth
6. Medium flowering response
7. Resistant to powdery mildew
Of the many commerical cultivars known to the present inventor, the most similar in comparison to `Jennifer` are the commercial cultivar `Sonjana` (unpatented) and the cultivar `Light Lavender II` (U.S. Plant Pat. No. 9,278). In comparison to `Sonjana`, `Jennifer` has a more intense flower color, its flowers are more above the foliage (less covered by leaves), and appears to be generally more disease resistant during the cultivation period.
In comparison to `Light Lavender II`, `Jennifer` has a more intense violet flower color, and lacks the distinct white eye of `Light Lavender II`. Leaves of `Jennifer` are narrower, and plant habit is considerably lower, the height of `Jennifer` being 11 cm as opposed to 15 cm for `Light Lavender II`.
The accompanying colored photographic drawing shows typical flower and foliage characteristics of `Jennifer`, with colors being as true as possible with illustrations of this type. In this regard, the colors in the illustration appear lighter than the actual R.H.S. values for `Jennifer`. The lighting is bright as to give the appearance of lighter, less-intense hues.
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 in early March and then grown in greenhouse at 20° C minimum temperature.
