Impatiens plant named ‘Balfiestarsa’

Abstract

A new and distinct cultivar of Impatiens plant named ‘Balfiestarsa’, characterized by its double-type salmon-colored flowers with light red-colored mottling, dark green-colored foliage, and vigorous, upright mounded growth habit.

Description

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

Variety denomination: ‘Balfiestarsa’.

BACKGROUND OF THE INVENTION

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

The new cultivar originated in a controlled breeding program in Elburn, Ill. during February 2003. The objective of the breeding program was the development of new compact Impatiens cultivars with fully double-type flowers, attractive flower and foliage coloration, and freely branching growth habit.

The new cultivar was the result of a self-pollination of the proprietary Impatiens walleriana breeding selection 3596-3-2, not patented, characterized by its white-colored flowers with coral-colored venation, medium green-colored foliage, and medium vigorous habit. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated self-pollination during October 2003 in a controlled environment at Elburn, Ill.

Asexual reproduction of the new cultivar by terminal stem cuttings since October 2003 at Elburn, Ill. and 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 following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balfiestarsa’ as a new and distinct cultivar of Impatiens plant:

• • 1. Double-type, salmon-colored flowers with light red-colored mottling;
  • 2. Dark green-colored foliage; and
  • 3. Vigorous, upright mounded growth habit.

Plants of the new cultivar differ from plants of the parent primarily in flower color, foliage color and growth habit.

Of the many commercially available Impatiens cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Salmon Sunrise’, U.S. Plant Pat. No. 9,691. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Salmon Sunrise’ in the following characteristics:

• • 1. Plants of the new cultivar are less floriferous than plants of ‘Salmon Sunrise’; and
  • 2. Plants of the new cultivar have a lighter flower color than plants of ‘Salmon Sunrise’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balfiestarsa’. The plants were grown in 10 cm pots for 6 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of a partially open flower on the left and a fully open flower on the right of ‘Balfiestarsa’.

DETAILED BOTANICAL DESCRIPTION

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 variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Jul. 6, 2005 between 3:00 p.m. and 4:00 p.m. under natural light conditions, in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 10 cm pots for 6 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65° F. to 75° F. (18° C. to 24° C.) during the day and approximately 55° F. to 62° F. (13° C. to 17° C.) during the night. Greenhouse light levels of 4,000 to 6,000 footcandles were maintained during the day.
