New Guinea plant named ‘DHARSDPINK’

Abstract

A new and distinct Impatiens cultivar named ‘DHARSDPINK’ is disclosed, characterized by large pink flowers, well branched plant form and good sun resistance. The new variety is an Impatiens, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Impatiens hawkeri.

Variety denomination: ‘DHARSDPINK’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring branch mutation of the patented commercial variety Impatiens ‘DHAR318’ U.S. Plant Pat. No. 25,118.

The new variety was discovered in May of 2012 by the inventor Gavriel Danziger a citizen of Israel in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by leaf cuttings. The cuttings are from an apical bud that has no more than two expanded leaves and three to four immature leaves present. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in June of 2012 and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DHARSDPINK’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

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

• • 1. Large flowers.
  • 2. Pink flower color.
  • 3. Well branched plants.
  • 4. Distinctive resistance to sunny conditions.

Plants of the new cultivar ‘DHARSDPINK’ are similar to plants of the parent, Impatiens ‘DHAR318’ in most horticultural characteristics, however, plants of the new cultivar ‘DHARSDPINK’ differ in the following;

• • 1. The new variety has pink flowers while the parent has salmon colored flowers.
  • 2. The new variety has smaller flowers than the parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DHARSDPINK’ are comparable to the unpatented commercial variety Impatiens ‘DHAR330’. The two Impatiens varieties are similar in most horticultural characteristics; however, the new variety ‘DHARSDPINK’ differs in the following:

• • 1. Flower color of the new variety is darker.
  • 2. Leaf color of the new variety is darker.
  • 3. Growth habit of the new variety is more compact.

Plants of the new cultivar ‘DHARSDPINK’ can also be compared to the patented commercial variety Impatiens ‘SAKIMP013’ U.S. Plant Pat. No. 19,597. The two Impatiens varieties are similar in most horticultural characteristics; however, the new variety ‘DHARSDPINK’ differs in the following:

• • 1. Flower color of the new variety is darker.
  • 2. Flower size of the new variety is larger.
  • 3. Leaf size of the new variety is larger.
  • 4. Growth habit of the new variety is more vigorous.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DHARSDPINK’ grown outdoors, in a 16 cm pot. Age of the plant photographed is approximately 14 weeks from a rooted cutting.

FIG. 2 illustrates a close up of the flowers and foliage.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
