New Guinea Impatiens plant named ‘Fisnics Burgsweet’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Fisnics Burgsweet’, and particularly characterized by the combined features of lavender and purple bi-colored flower color; medium to large, round, almost flat flowers borne well above the foliage; uniform, dark green foliage, relatively wide leaves; medium sized to larger, round and bushy plant habit; and early to medium flowering response.

Description

Genus and species of the plant claimed: Impatiens hawkeri.

Variety denomination: ‘Fisnics Burgsweet’.

BACKGROUND OF THE INVENTION

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

‘Fisnics Burgsweet’ is the product of a planned breeding program and originated from a hybridization made by the inventor, Birgit C. Hofmann, in a controlled breeding program in Hillscheid, Germany, in 2000.

The female parent was the variety ‘Harmony Raspberry Cream’ (unpatented), which is characterized by white to light pink flower color with cherry red stripes on petals, very dark, almost black, foliage, and medium sized plant habit.

The male parent of ‘Fisnics Burgsweet’ was ‘Kispix’ (unpatented), having pink and red bi-colored flowers, medium green foliage, and approximately medium sized plant habit.

‘Fisnics Burgsweet’ was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor in April, 2001 in a greenhouse in Galdar, Gran Canaria, Spain.

The first act of asexual reproduction of ‘Fisnics Burgsweet’ was accomplished when vegetative cuttings were taken from the initial selection in July 2001 in a controlled environment in Galdar, Gran Canaria, Spain, by, or under the supervision of the inventor.

Horticultural examination of plants grown from these cuttings initiated in the spring of 2002 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisnics Burgsweet’ are firmly fixed and are retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

‘Fisnics Burgsweet’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length, without, however, any variation in genotype. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Federal Republic of Germany, under greenhouse conditions which approximate those generally used in commercial practice.

BRIEF SUMMARY OF THE INVENTION

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

• • 1. Lavender and purple bi-colored flower color;
  • 2. Medium to large, round, almost flat flowers borne well above the foliage;
  • 3. Uniform, dark green foliage, relatively wide leaves;
  • 4. Medium sized to larger, round and bushy plant habit; and
  • 5. Early to medium flowering response.

Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fisnics Burgsweet’ is the parental variety ‘Kispix’ and the variety ‘Fisimp 172’ (U.S. Plant Pat. No. 13,699).

In comparison to ‘Kispix’, ‘Fisnics Burgsweet’ has a more purple-violet flower color whereas ‘Kispix’ has pink flowers, as well as wider and more blurred red-purple pattern of secondary flower color, and darker green foliage.

In comparison to ‘Fisimp 172’, ‘Fisnics Burgsweet’ has a more blurred pattern of secondary petal color, while ‘Fisimp 172’ has narrow, but distinct reddish stripes. Furthermore, ‘Fisnics Burgsweet’ has longer peduncles, darker and more glossy foliage, more even and better branched plant habit.

DETAILED BOTANICAL DESCRIPTION

In the following description color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined indoors from plants growing in a greenhouse in May 2003, Hillscheid, Germany.

The description is based on plants which were planted as rooted cuttings in 12 cm pots in late February 2003, and then grown in the greenhouse at a minimum temperature of 16° C. Most observations and measurements were made after the beginning of flowering in mid May, when the plants were about 12 weeks old.
