New Guinea Impatiens plant named ‘Balcelipurt’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Balcelipurt’ characterized by its large light purple-colored flowers with darker purple-colored mid-rib, medium green-colored foliage, uniform medium upright, mounded growth habit, and good basal branching.

Description

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

Variety denomination: ‘Balcelipurt’.

BACKGROUND OF THE INVENTION

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

The new cultivar was developed by the inventor in a controlled breeding program during June 2000 at Arroyo Grande, Calif. The objective of the breeding program was to develop New Guinea Impatiens cultivars with numerous large flowers, excellent basal branching, and upright compact to moderate growth habits.

The female (seed) parent of ‘Balcelipurt’ was the commercially available Impatiens hawkeri cultivar ‘Toga’ (U.S. Plant Pat. No. 10,304) characterized by its compact upright growth habit, light lavender-colored flowers, and dark green-colored foliage. The male (pollen) parent of ‘Balcelipurt’ was ‘BFP-796’ (U.S. Plant Pat. No. 11,486), characterized by its vigorous upright habit, apricot-colored flowers and medium green-colored foliage. ‘Balcelipurt’ was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination in January of 2001 at Arroyo Grande, Calif. The new Impatiens was initially designated ‘3246-1’.

Asexual reproduction of the new cultivar by terminal stem cuttings taken in West Chicago, Ill., since 2001, has demonstrated that the new cultivar reproduces true to type with all the 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 variance in genotype.

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

• • 1. Exhibits large round light purple-colored flowers with darker purple-colored mid-rib.
  • 2. Forms medium green-colored foliage,
  • 3. Exhibits a good basal branching character, and
  • 4. Exhibits a medium, upright mounded growth habit.

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

Of the many commercially available New Guinea Impatiens cultivars known to the inventor, ‘Balcelipurt’ is most similar to ‘Purple Star’ (U.S. Plant Pat. No. 10,091). However, in side-by-side comparisons conducted in West Chicago, Ill., plants of the new cultivar differed from plants of ‘Purple Star’ in the following characteristics:

• • 1. Plants of the new cultivar have larger leaves than plants of ‘Purple Star’,
  • 2. Plants of the new cultivar have larger flowers than plants of ‘Purple Star’, and
  • 3. Plants of the new cultivar have less pubescence on the leaves and stems than the plants of ‘Purple Star’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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 describes the colors of ‘Balcelipurt’. The plants were grown from rooted cuttings for 11 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of a single flower of ‘Balcelipurt’.

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 Sep. 11, 2003 between 1:00 and 1:45 p.m. under natural light conditions.

The following measurements and comparisons describe plants produced from cuttings taken from stock plants and grown in West Chicago, Ill. under greenhouse conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 11 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 72° F. during the day and approximately 65° F. during the night. Greenhouse light levels were maintained at approximately 4,000-7,000 footcandles during the day.
