Title: New Guinea Impatiens plant named ‘Ovation Red Spice’

Description:
Botanical classification/cultivar designation:  Impatiens hawkeri  cultivar Ovation Red Spice. 
     BACKGROUND OF THE INVENTION 
     The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as  Impatiens hawkeri , and hereinafter referred to by the cultivar name ‘Ovation Red Spice’. 
     The new Impatiens is a product of a planned breeding program conducted by the Inventor in Ashtabula, Ohio and Lompoc, Calif. The objective of the breeding program is to develop new freely flowering Impatiens cultivars with interesting flower and foliage colors. 
     The new Impatiens originated from a cross-pollination made by the Inventor during the winter of 1997 of a proprietary  Impatiens hawkeri  seedling selection designated as code number 95-306-9, not patented, as the female, or seed parent, with a proprietary  Impatiens hawkeri  seedling selection designated as code number 97-1244-1, not patented, as the male, or pollen parent. The cultivar Ovation Red Spice was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Ashtabula, Ohio. 
     Asexual reproduction of the new cultivar by terminal cuttings taken at Lompoc, Calif., since August, 1998, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations. Plants of the new Impatiens differ from the parent selections in plant size and habit, leaf color, and flower size and color. 
     SUMMARY OF THE INVENTION 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ovation Red Spice’. These characteristics in combination distinguish ‘Ovation Red Spice’ as a new and distinct Impatiens cultivar: 
     1. Mounded plant habit. 
     2. Freely branching growth habit, dense and full plants. 
     3. Dark green leaves. 
     4. Freely flowering habit with flowers positioned above or beyond the foliage. 
     5. Large, red-colored flowers. 
     6. Tolerant to full sun conditions and low and high temperatures. 
     Plants of the new Impatiens can be compared to plants of the cultivar Danhardkrd, disclosed in U.S. Plant Pat. No. 12,143. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Impatiens differed from plants of the cultivar Danhardkrd, in the following characteristics: 
     1. Plants of the new Impatiens were shorter and more mounded (not as upright) than plants of the cultivar Danhardkrd. 
     2. Plants of the new Impatiens had broader leaves than plants of the cultivar Danhardkrd. 
     3. Plants of the new Impatiens had larger flowers than plants of the cultivar Danhardkrd. 
     Plants of the new Impatiens can also be compared to plants of the cultivar Tarawa, disclosed in U.S. Plant Pat. No. 10,320. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Impatiens differed from plants of the cultivar Tarawa, in the following characteristics: 
     1. Plants of the new Impatiens were shorter than plants of the cultivar Tarawa. 
     2. Plants of the new Impatiens had larger leaves than plants of the cultivar Tarawa. 
     3. Plants of the new Impatiens had larger flowers than plants of the cultivar Tarawa. 
     4. Flower color of plants of the new Impatiens was darker red than flower color of plants of the cultivar Tarawa. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPH 
     The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘Ovation Red Spice’ grown in a container. 
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The cultivar Ovation Red Spice has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following detailed botanical description describe plants grown in Lompoc, Calif., during the winter, under commercial practice in a fiberglass-covered greenhouse. Plants used in the following description were grown in 15-cm containers for about seven to nine weeks after planting rooted cuttings. During the production period, day temperatures were about 21 to 24° C., night temperatures were about 16 to 18° C., and light levels were about 3,000 to 4,000 foot-candles. 
     In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
