Abstract

A new Impatiens plant particularly distinguished by double, rose-shaped, rose 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 Ror07’.
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 Ror07’. The new cultivar originated from a sib cross made in June 2004 in Andijk, The Netherlands. The parents were the proprietary red star-flowered Impatiens plant ‘ID03-20-5’ (unpatented) and the proprietary red star-flowered Impatiens plant ‘ID03-20-7’ (unpatented). The seeds produced by the sib cross were sown in September 2004. A single plant selection was chosen for further evaluation and for asexual propagation in December 2004.
The new cultivar was created in 2004 and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands and Gilroy, Calif. over a two-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 Dec. 14, 2006, in Canada on Apr. 19, 2006 and in Japan on Nov. 1, 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, rose 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 15 to 16 weeks old, grown in a greenhouse in Hillscheid, Germany during the spring. The photograph was taken in September 2006.
FIG. 1 shows the overall plant habit including blooms, buds, and foliage.
FIG. 2 shows a close-up of the mature flower.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Silte Ror07’. 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.
