plant named ‘Silt Oragsar’

Abstract

A new Impatiens plant named ‘Silt Oragsar’ particularly distinguished by the fully-double orange-red and white bi-colored flowers, has early flowering, nicely contrasting dark green foliage, and compact and low mounding plant habit with good branching.

Description

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

Varietal denomination: ‘Silt Oragsar’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Impatiens, botanically known as Impatiens walleriana, and hereinafter referred to by the variety name ‘Silt Oragsar’.

‘Silt Oragsar’ is a product of a planned breeding program. The new cultivar has fully-double orange-red and white bi-colored flowers, has early flowering, nicely contrasting dark green foliage, and compact and low mounding plant habit with good branching.

‘Silt Oragsar’ originated from a hybridization made in April 2007 in a controlled breeding environment in Andijk, Netherlands. The female parent was the unpatented, proprietary plant designated ‘IDO3-27-11’, with scarlet and white bi-colored flowers.

The male parent of ‘Silt Oragsar’ was an unpatented proprietary plant designated as ‘IDO3-30-11’, with salmon and white bi-colored flowers. The resultant seed was sown in June 2007.

‘Silt Oragsar’ was selected as one flowering plant within the progeny of the stated cross in the September 2007 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Silt Oragsar’ was accomplished when vegetative cuttings were propagated from the initial selection in September 2007 in a controlled environment in Andijk, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in September 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Silt Oragsar’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Silt Oragsar’ 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.

Plant Breeder's Rights for this cultivar were applied for in Canada on Feb. 18, 2010 (#10-6848), in CPVO on Mar. 18, 2010 (#2010/0685), and in Switzerland on Oct. 29, 2009 (#309-2620). ‘Silt Oragsar’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Impatiens as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Silt Oragsar’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety growing in a 4 inch pot, and a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in Gilroy, Calif. from plants growing in a greenhouse trial in April 2010. These plants were approximately 9-10 weeks of age. The plant descriptions and measurements were taken on those very same plants later in early June 2010 after growing outdoors a few weeks in a 8 inch pot. They were about 16 weeks of age.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
