USPP16302P2 - New Guinea Impatiens plant named ‘Balcebimpu’ - Google Patents

Abstract

A new and distinct New Guinea Impatiens plant named ‘Balcebimpu’ characterized by its large, single purple-colored flowers, dark green-colored glossy foliage, good basal branching, and upright and mounded growth habit.

Description

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

Variety denomination: ‘Balcebimpu’.

BACKGROUND OF THE INVENTION

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

The new cultivar originated in a controlled breeding program during May 2001 at Arroyo Grande, Calif. The objective of the breeding program was the development of new Impatiens cultivars with numerous, single flowers, excellent basal branching, and compact, mounded growth habit.

The female (seed) parent of the new cultivar was the proprietary Impatiens hawkeri selection designated 2835-1, not patented, characterized by its open, loose habit and dull foliage appearance. The male (pollen) parent of the new cultivar was the proprietary Impatiens hawkeri selection designated 2601-1, not patented, characterized by its dark purple-colored flowers and medium green-colored foliage. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross-pollination during October 2001 at Arroyo Grande, Calif.

Asexual reproductiom of the new cultivar by terminal stem cuttings since October 2001 at Arroyo Grande, Calif. 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 ‘Balcebimpu’ as a new and distinct cultivar of New Guinea Impatiens plant:

• • 1. Large, single, bright purple-colored flowers.
  • 2. Dark green-colored glossy foliage.
  • 3. Good basal branching character.
  • 4. Upright and mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in plant habit and foliage appearance and from the male parent primarily in flower color and foliage color.

Of the many commercially available New Guinea Impatiens cultivars known to the inventor, the most similar to the new cultivar is the variety ‘Balcebpurp’, U.S. Plant Pat. No. 13,999. However, in side-by-side comparisons conducted at West Chicago, Ill., plants of the new cultivar differ from plants of ‘Balcebpurp’ in the following characteristics:

• • 1. Plants of the new cultivar have smaller leaves than plants of ‘Balcebpurp’.
  • 2. The flowers of the new cultivar are more blue in color than the flowers of ‘Balcebpurp’.

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 differ slightly from the color values cited in the detailed description, which accurately describe the colors of ‘Balcebimpu’. The plants were grown in 10 cm pots for 9 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balcebimpu’.

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

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 Sep. 24, 2004 between 10:00 and 11:45 a.m. under natural light conditions.

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 9 weeks using a soil-less 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.
