New Guinea Impatiens plant named `Neptis`

Abstract

A new and distinct cultivar of New Guinea impatiens plant named `Neptis`, characterized by its flat and rounded red and pink bi-colored flowers; freely flowering habit; outwardly spreading, rounded and mounded growth habit; and medium green, glossy, non-variegated foliage.

Description

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

The new cultivar is a product of a planned breeding program conducted by the inventor in Gensingen, Germany. The objective of the breeding program was to develop new varieties that have a uniform plant habit, attractive flower colors, good flower form and numerous flowers per plant.

The new cultivar originated from a cross made by the inventor of a proprietary seedling selection identified as N213 as the male, or pollen parent, with the proprietary seedling selection identified as Z661 as the female, or seed patent. The cultivar Neptis was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany. Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction. The following traits have been repeatedly observed and are determined to be the unique characteristics of `Neptis`. These characteristics in combination distinguish `Neptis` as a new and distinct cultivar: 1. Flat and rounded red and pink bi-colored flowers. 2. Freely flowering habit. 3. Outwardly spreading, rounded and mounded growth habit. 4. Medium green, glossy, non-variegated foliage.

The new New Guinea Impatiens is similar in flower color to the New Guinea Impatiens cultivar `Celebration Cherry Star` (disclosed in U.S. Plant Pat. No. 8,407). However in side-by-side comparisons in Encinitas, Calif. under commercial practice, plants of the new New Guinea Impatiens differed from plants of the cultivar (`Guadeloupe` in the following characteristics:

1. Plants of the new New Guinea Impatiens are more outwardly spreading, mounded and rounded than plants of the cultivar `Celebration Cherry Star`.

2. Plants of the new New Guinea Impatiens are more vigorous and taller and wider than plants of the cultivar (`Celebration Cherry Star`.

3. Plants of the new New Guinea Impatiens are more freely branching than plants of the cultivar `Celebration Cherry Star`.

4. Leaves of plants of the new New Guinea Impatiens are larger than leaves of plants of the cultivar `Celebration Cherry Star`.

5. Upper surfaces of leaves of plants of the new New Guinea Impatiens are lighter green than upper surfaces of leaves of plants of the cultivar `Celebration Cherry Star`.

6. Flowers of plants of the new New Guinea Impatiens are positioned above the foliage whereas flowers of plants of the cultivar `Celebration Cherry Star` are positioned slightly below the foliage.

A detailed comparison of plants of the new New Guinea Impatiens and the cultivar `Celebration Cherry Star` appears in Chart A at the end of the specification.

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The first photograph comprises a top perspective view of a typical plant of `Neptis`.

The second photograph comprises a close-up view of typical flowers and upper (left) and lower (right) surfaces of leaves of the cultivars `Celebration Cherry Star` (top) and `Neptis` (bottom of photo).

Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.

The cultivar Neptis 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, measurements and comparisons describe plants grown 10-cm pots in Encinitas, Calif. under commercial practice in a fiberglass-covered greenhouse with day temperatures ranging from 23 to 29C. and night temperatures ranging from 16 to 18C. and light levels averaging 3,000 footcandles.
