Impatiens plant named ‘Silte Pinkcie’

Abstract

A new Impatiens plant particularly distinguished by numerous medium to large, double, deep-pink outer petals and white to light pink inner petals with white centers, medium-green foliage with elliptical leaves, an early flowering response, floriferous throughout the summer, good rain tolerance, a medium-sized, round and bushy plant habit with good branching ability, is disclosed.

Description

Genus and species: Impatiens walleriana.

Variety denomination: ‘Silte Pinkcie’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Impatiens, botanically known as Impatiens walleriana, and hereinafter referred to by the cultivar name ‘Silte Pinkcie’. The new cultivar originated from a hybridization made in January 2003 in Andijk, The Netherlands. The female parent was the proprietary white-flowered Impatiens plant ‘IW-522-1’ (unpatented), while the male parent was the proprietary violet-flowered Impatiens plant ‘IW-68-2’ (unpatented). The seeds produced by the hybridization were sown Andijk, The Netherlands in April 2003. A single plant selection was chosen for further evaluation and for asexual propagation in July 2003 in Andijk, The Netherlands.

The new cultivar was created in 2003 in Andijk, The Netherlands and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands and Hillscheid, Germany over a two-year period. ‘Silte Pinkcie’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Canada on Oct. 17, 2005 and with the European Union on Nov. 18, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Andijk, Netherlands, and Hillscheid, Germany.

• • 1. Numerous medium to large, semi-double, deep-pink flowers with white centers;
  • 2. Medium-green foliage with elliptical leaves;
  • 3. A medium-sized, round and bushy plant habit with good branching ability;
  • 4. An early flowering response;
  • 5. Floriferous throughout the summer; and
  • 6. Good rain tolerance for a double-flowered variety.

DESCRIPTION OF PHOTOGRAPH

This new Impatiens plant is illustrated by the accompanying photograph which shows overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is close-up of a portion of a 10-week old plant, grown in a greenhouse in Hillscheid, Germany in late May 2005.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Silte Pinkcie’. The data which defines these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken in mid September on 9- to 10-week old un-pinched plants which had been planted as rooted cuttings in 12-cm pots in mid-July 2005 and grown in a greenhouse at a minimum temperature of 21° C. Color readings were taken under natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
