Impatiens plant named ‘Silte Reeda’

Abstract

A new Impatiens plant particularly distinguished by double, rose-shaped, red flowers, semi-compact, upright, outwardly spreading and mounded plant habit, free flowering, good basal branching, and moderately vigorous growth habit, is described.

Description

Genus and species: Impatiens walleriana.

Variety denomination: ‘Silte Reeda’.

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 Reeda’. The new cultivar originated from a controlled self pollination made in January 2003 in Andijk, The Netherlands. The parent was the proprietary red-flowered Impatiens plant ‘ID03-14-4’ (unpatented). The seeds produced by the controlled self pollination were sown in April 2003. A single plant selection was chosen for further evaluation and for asexual propagation in July 2003.

The new cultivar was created in 2003 and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands and Gilroy, Calif. over a three and a half year period. The plant has also been trialed at Gilroy, Calif., Andijk, The Netherlands and Hillscheid, Germany. 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 with the European Union on Nov. 13, 2006.

SUMMARY OF THE INVENTION

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

• • 1. Double, rose-shaped, red flowers;
  • 2. Semi-compact, upright, outwardly spreading and mounded plant habit; and
  • 3. Free flowering, good basal branching and moderately vigorous growth habit.

DESCRIPTION OF PHOTOGRAPH

This new Impatiens plant is illustrated by the accompanying photograph which shows the 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 of a whole plant about 10 weeks old, grown in a greenhouse in Hillscheid, Germany during the spring. The photograph was taken in May 2006 and shows the overall plant habit including blooms, buds, and foliage.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Silte Reeda’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. in a trial setting. The plant history was taken on 26-week-old plants grown in 6-inch containers in a greenhouse during the fall and winter seasons. The plants had one plant growth regulator treatment and one terminal pinch after cuttings were transplanted. Color readings were taken under natural light in the greenhouse in January. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001). Texture description data was viewed with a dissecting microscope.
