Impatiens plant named ‘HGI-1038-1’

Abstract

A new and distinct Impatiens plant named ‘HGI-1038-1’ characterized by having a typical compact growth, small flowers and a unique soft salmon color of the flower.

Description

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

Variety denomination: HGI-1038-1.

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 ‘HGI-1038-1’.

The new cultivar originated from a cross made in a controlled breeding program in the village of Hem, the Netherlands. The female parent is ‘IB-9-1’ (unpatented). The male parent is ‘IB-14-1’ (unpatented). ‘HGI-1038-1’ was discovered and selected by the inventor, in November 1999, as a flowering plant within the progeny of the stated cross in a controlled environment in the village of Hem, the Netherlands.

‘HGI-1038-1’ is a product of a planned breeding program conducted by the inventor Johannes J.G. Sijm, and selected in a controlled cultivated environment in the village of Hem, the Netherlands. Asexual reproduction of the new cultivar by vegetative cuttings used in propagation was first performed in December 1999, in the village of Hem, the Netherlands and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and reproduce true to type in successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘HGI-1038-1’ which in combination distinguish this Impatiens as a new and distinct cultivar:

1. compact growth;

2. small flowering;

3. small leaves; and

4. a unique soft salmon flower color

‘HGI-1038-1’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in the village of Hem, the Netherlands under conditions which closely approximate those generally used in commercial practice.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘HGI-1038-1’ is the cultivar ‘Firefly Salmon’. The overall habit and appearance of ‘HGI-1038-1’ and ‘Firefly Salmon’ are comparable, however the flowers of ‘HGI-1038-1’ are RHS 49C in color and 2.5 cm in both length and width, whereas the flowers of ‘Firefly Salmon’ are RHS 43C in color and 2.2 cm in length and 2 cm in width.

In comparison to the instant plant, both parental cultivars have a more vigorous plant habit. When grown under the same conditions in a greenhouse as potted plants, the parental cultivars are 50% taller than ‘HGI-1038-1’. The flower color of parental cultivars differ from ‘HGI-1038-1’. Flowers of the female parental cultivar are RHS 55A; flowers of the male parental cultivar are RHS 43A, and are larger, 4-5 cm in diameter.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic illustrations show typical flower and foliage characteristics of ‘HGI-1038-1’ with colors being as true as possible with illustrations of this type.

The first drawing shows the plant in its entirety, with compact growth and numerous flowers.

The second drawing shows an enlargement of one typical flower.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar as grown in the village of Hem, the Netherlands, under conditions which closely approximate those generally used in commercial practice. The plant grows well under normal greenhouse conditions, however the temperature should not decrease below 15 degrees Centigrade. Shading of the plants in high light conditions is essential. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately noon in the village of Hem, the Netherlands.
