Description

Botanical designation: Impatiens walleriana.

Variety denomination: ‘Danmuorglow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Double Impatiens plant, botanically known as Impatiens walleriana, herein after referred to by the cultivar name ‘Danmuorglow’.

The new Double Impatiens cultivar is a product of a planned breeding program conducted by the Inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program is to develop a new Double Impatiens variety with compact and rounded, growth habit, orange colored flowers, green colored leaves, and good branching habit.

The new Impatiens cultivar originated from a cross made in a controlled breeding program by the Inventor, Gabriel Danziger, in 2003 in Moshav Mishmar Hashiva, Israel. The female or seed parent is the Impatiens walleriana cultivar designed ‘477 HF’ (unpatented) and is characterized by having single, orange colored flowers and a compact, growth habit. The male or pollen parent is the Impatiens walleriana cultivar designated ‘326 HF’ (unpatented) and is characterized by having semi-double, salmon colored flowers. ‘Danmuorglow’ was discovered and selected by the Inventor in May of 2003 as a flowering plant within the progeny of the stated cross in a controlled environment in. Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar by stem tip cutting was first performed in July of 2003 in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true-to-type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of the new Double Impatiens cultivar ‘Danmuorglow’ which in combination distinguish this Double Impatiens as a new and distinct cultivar:

    • 1. Compact and rounded growth habit;
    • 2. Double, orange colored flowers;
    • 3. Green colored leaves; and
    • 4. Good branching.

Plants of the new Double Impatiens ‘Danmuorglow’ differ from plants of the parents, ‘477 HF’ (unpatented) and ‘326 HF’ (unpatented) in the following characteristics described in Table 1:

Of the many commercial cultivars known to the present Inventor, the most similar in comparision to the new Double Impatiens cultivar ‘Danmuorglow’ is a Double Impatiens called ‘Fiesta Deep Orange’. In side-by-side comparisons conducted in Moshav Mishmar Hashiva, Israel, plants of ‘Fiesta Deep Orange’ differed from plants of ‘Danmuorglow’ primarily in flower color and leaf color as provided in Table 2:

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance of the new Double Impatiens cultivar ‘Danmuorglow’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the color of the ‘Danmuorglow’.

The first photograph shows a side view perspective of a typical ‘Danmuorglow’ potted plan at 3 months.

The second photograph shows a close-up view of typical flowers and leaves of ‘Danmuorglow’ at 3 months.

 DETAILED BOTANICAL DESCRIPTION

The new Double Impatiens cultivar ‘Danmuorglow’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and daylength, without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of the new Double Impatiens cultivar ‘Danmuorglow’ as grown in a greenhouse in Moshav Mishmar Hashiva, Israel, under conditions which closely resemble those generally used in commercial practice. Plants of ‘Danmuorglow’ are grown in a greenhouse with day temperatures ranging from 25° C. to 30° C. and night temperatures ranging from 18° C. to 25° C. Plants of ‘Danmuorglow’ are fertilized up to a level of 100 ppm N, 35 ppm P and 120 ppm K. The age of the plants described is 8 weeks. The photographs and descriptions were taken during the winter when outdoor day temperatures ranged from 15° C. to 25° C. and outdoor night temperatures ranged from 10° C. to 15° C.

Color references are made with The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 12 noon in Moshav Mishmar Hashiva, Israel.
