Double Impatiens plant named ‘Balfiesink’

Abstract

A new and distinct Double Impatiens plant named ‘Balfiesink’ characterized by its fully double dark pink/pale pink bicolor flowers, dark green-colored foliage, compact, upright and mounded growth habit and excellent basal branching.

Description

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

Variety denomination: ‘Balfiesink’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Double Impatiens plant botanically known as Impatiens walleriana and hereinafter referred to by the cultivar name ‘Balfiesink’.

The new cultivar was developed by the inventor in a controlled breeding program during June 1999 at Elburn, Ill. The objective of the breeding program was to develop new Impatiens cultivars with numerous fully double flowers, excellent basal branching and upright compact growth habit.

The female (seed) parent of ‘Balfiesink’ was the proprietary Impatiens walleriana selection designated ‘3267c-3’ (not patented) characterized by its vigorous growth habit, semi-double rose/white bicolor flowers and medium green foliage. The male (pollen) parent of ‘Balfiesink’ was the proprietary Impatiens walleriana selection designated ‘3309-1’ (not patented) characterized by its vigorous upright habit, semi-double red/white bicolor flowers and dark green foliage. ‘Balfiesink’ was discovered and selected as one flowering plant within the progeny of the stated cross-pollination in February of 2000 and was initially designated ‘15799-2’.

Asexual reproduction of the new cultivar by terminal stem cuttings since February 2000 at West Chicago, Ill., has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any change in genotype.

It was repeatedly found that the cultivar of the present invention:

• • 1. Exhibits fully double dark pink/pale pink bicolor flowers,
  • 2. Forms dark green-colored foliage,
  • 3. Exhibits a good basal branching character, and
  • 4. Exhibits a compact, upright and mounded growth habit.

Plants of the new cultivar differ from plants of the parents primarily in flower form.

Of the many commercially available Double Impatiens cultivars known to the inventor, the most similar to ‘Balfiesink’ is ‘Sparkler Rose’ (U.S. Plant Pat. No. 9,630). However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Sparkler Rose’ by the following characteristics:

• • 1. Plants of the new cultivar have larger leaves of a lighter green color than plants of ‘Sparkler Rose’, and
  • 2. The flowers of the plants of the new cultivar are redder in color than the flowers of the plants of ‘Sparkler Rose’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describe the colors of ‘Balfiesink’. The plants were grown for 8 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balfiesink’.

DETAILED DESCRIPTION

The chart used in the identification of colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where general color terms of ordinary significance are used. The color values were determined on Jul. 16, 2003 between 10:00 and 11:45 a.m. under natural light conditions.

The following measurements and comparisons describe plants produced from cuttings taken from stock plants and grown under greenhouse conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 8 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-75° F. during the day and approximately 55°-62° F. during the night. Greenhouse light levels were maintained at approximately 4,000-6,000 footcandles during the day.
