New Guinea impatiens plant named ‘Fisupnic Kirmag’

Abstract

A new New Guinea Impatiens plant particularly distinguished by large, nearly round, brilliant, purple-red-colored flowers, medium green foliage, relatively narrow leaves, a mounded, semi-spherically shaped, moderately tight plant habit and medium flowering response, is described.

Description

Genus and species: Impatiens hawkeri W. Bull.

Variety denomination: ‘Fisupnic Kirmag’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of New Guinea Impatiens, botanically known as Impatiens hawkeri W. Bull, and hereinafter referred to by the cultivar name ‘Fisupnic Kirmag’. The new cultivar originated from a hybridization made in the year 2003 in Hillscheid, Germany. The female parent was the proprietary New Guinea Impatiens plant ‘K03-3186-1’ (unpatented), while the male parent was the proprietary Impatiens plant ‘K03-2428-2’ (unpatented). The seeds produced by the hybridization were sown in a greenhouse in Moncarapacho, Portugal in the fall of 2003. A single plant selection was chosen for further evaluation and for asexual propagation in the spring of 2004 in Portugal.

The new cultivar was created in 2003 in Hillscheid, Germany and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Moncarapacho, Portugal and Hillscheid, Germany over a three-year period. ‘Fisupnic Kirmag’ 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 present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Canada on Mar. 30, 2007, and in Switzerland, on May 23, 2007. ‘Fisupnic Kirmag’ has not been made publicly available more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Hillscheid, Germany, and in Langley, British Columbia, Canada.

• • 1. Brilliant, purple-red flower color;
  • 2. Large flowers, nearly round;
  • 3. Medium green foliage with relatively narrow leaves;
  • 4. Mounded, semi-spherically shaped, moderately tight plant habit; and
  • 5. Medium flowering response.

DESCRIPTION OF PHOTOGRAPH

This new New Guinea Impatiens plant is illustrated by the accompanying photograph which shows overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a whole plant about 13 to 14 weeks old, grown in a greenhouse in Hillscheid, Germany, in the spring of 2007.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Fisupnic Kirmag’. The data which defines these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 10- to 12-week-old plants which were planted as rooted cuttings in 12-cm pots in late February 2007, and then grown in a greenhouse at a minimum temperature of 16° C. Color readings were taken under natural light in the greenhouse. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

‘Fisupnic Kirmag’ differs from the male parent ‘K03-2428-2’ (unpatented), by having a purple-red flower color while ‘K03-2428-2’ has a purple flower color. In addition, ‘Fisupnic Kirmag’ has a taller plant habit than ‘K03-2428-2’.

‘Fisupnic Kirmag’ differs from the commercial cultivar ‘Balcelichey’ (U.S. Plant Pat. No. 15,805) by having a more bluish hue of flower color and rounder flowers, while ‘Balcelichey’ has weakly zygomorphic flowers. Additionally, plants of ‘Fisupnic Kirmag’ are taller, especially with regard to the height of the foliage.

‘Fisupnic Kirmag’ differs from the cultivar ‘Fisimp 551’ (U.S. Plant Pat.
