Description

Latin name of the genus and species of the plant claimed: Impatiens walleriana.

Varietal denomination: ‘Silt Cher’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Impatiens, botanically known as Impatiens walleriana, and hereinafter referred to by the variety name ‘Silt Cher.’

‘Silt Cher’ is a product of a planned breeding program. The new cultivar ‘Silt Cher’ has light cherry red to carmine flower color, rose-shaped, double type flowers, dark green foliage, and low and mounding plant habit.

‘Silt Cher’ originated from a hybridization made in April 2003 in a controlled breeding program in Andijk, Netherlands. The female parent was an unpatented hybrid seedling identified as ‘ID03-25-2’ with salmon flower color and single flower type.

The male parent of ‘Silt Cher’ was an unpatented hybrid seedling identified as ‘ID03-29-2’ with carmine colored, single-type flowers.

The resulting seeds were sown in June 2003. ‘Silt Cher’ was selected as one flowering plant within the progeny of the stated cross in August 2003 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Silt Cher’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 2004 in a controlled environment in Andijk, Netherlands.

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2004 in Andijk, Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Silt Cher’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Silt Cher’ 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.

Plant Breeder's Rights for this cultivar were applied for in Canada on Dec. 24, 2007 and in the European Union on Jul. 21, 2008. ‘Silt Cher’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Silt Cher’ with colors being as true as possible with an illustration of this type. The photographic drawing, taken in late May 2008, shows a 15 week old greenhouse grown plant of the new variety.

 DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, mainly in late May 2008 on 14-15 week old plants that were growing on benches in a greenhouse. Culture of these plants had started around February 10 when rooted cuttings were potted in 12 cm pots and grown at moderately warm temperatures, between 15 and 20° C. in daytime.

Color Chart used: Royal Horticultural Society Colour Chart (RHS) 2001.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown in a greenhouse in Hillscheid, Germany. The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Impatiens as a new and distinct variety.

    • 1. Light cherry red to carmine, double-type flowers
    • 2. Dark green foliage, relatively round leaf shape
    • 3. Well branched and relatively low and mounding plant habit
    • 4. Medium plant size
    • 5. Suitable as a bedding plant, for containers and as a flowering pot plant near or in the house.

COMPARISON WITH COMMERCIAL CULTIVARS

‘Silt Cher’ differs from the commercial variety ‘Didi Chered,’ U.S. Plant Pat. No. 15,905, in that ‘Silt Cher’ has somewhat smaller flowers, stronger branching and a more compact plant habit.

‘Silt Cher’ differs from the commercial variety ‘Silte Rossa,’ U.S. Plant Pat. No. 18,007, by having a somewhat more reddish overall flower color and by a more vigorous growth habit.
