New Guinea impatiens plant named ‘Balcelilae’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Balcelilae’, characterized by its light purple-colored flowers; upright and mounded plant habit; good basal branching and dark green leaves.

Description

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 Balcelilae.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program was to develop new cultivars with freely-branching growth habit, numerous large flowers, and attractive flower and foliage colors.

The new Impatiens originated from a cross made by the Inventor of an unidentified selection of Impatiens hawkeri as the male, or pollen parent, with the Impatiens hawkeri cultivar Moorea, disclosed in U.S. Plant Pat. No. 9,147 as the female, or seed parent. The cultivar Balcelilae was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Arroyo Grande, Calif. in 1997. Plants of the new Impatiens and the cultivar Moorea differ primarily in flower color.

Asexual reproduction of the new cultivar by terminal cuttings taken at Arroyo Grande, Calif., has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balcelilae’. These characteristics in combination distinguish ‘Balcelilae’ as a new and distinct cultivar:

1. Light purple-colored flowers with white centers.

2. Upright and mounded plant habit.

3. Good basal branching.

4. Dark green leaves.

The new Impatiens can be compared to the cultivar, Light Lavender II, disclosed in U.S. Plant Pat. No. 9,278. However, in side-by-side comparisons conducted by the Inventor in Arroyo Grande, Calif., plants of the new Impatiens differ from plants of the cultivar Light Lavender II in the following characteristics:

1. Plants of the new Impatiens have smaller leaves with shorter petioles than plants of the cultivar Light Lavender II.

2. Plants of the new Impatiens are not as freely flowering as plants of the cultivar Light Lavender II.

3. Flower color of plants of the new Impatiens is darker and more blue than flower color of plants of the cultivar Light Lavender II.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new cultivar as true as it is reasonably possible to obtain in colored reproduction of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Balcelilae’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Balcelilae has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations and measurements describe plants about 10 weeks after planting rooted cuttings and grown 10-cm pots in West Chicago, Ill., under commercial practice in a double-layered acrylic-covered greenhouse with day temperatures about 21° C., night temperatures about 19° C., and light levels about 2,500 to 3,500 footcandles.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
