Title: New Guinea Impatiens plant named ‘Tamar True Pink’

Description:
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 Tamar True Pink. 
     The new Impatiens is a product of a planned breeding program Inventor in Maasland, The Netherlands. The objective of the breeding program is to develop new Impatiens cultivars with uniform plant habit and attractive flower and foliage colors. 
     The new Impatiens originated from a cross made by the Inventor in 1996 of the  Impatiens hawkeri  cultivar Tahiti, disclosed in U.S. Plant Pat. No. 8,601, as the male, or pollen parent, with the Inventor&#39;s proprietary  Impatiens hawkeri  selection code number 942102, not patented, as the female, or seed parent. The cultivar Tamar True Pink was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Maasland, The Netherlands in 1996. 
     Asexual reproduction of the new cultivar by terminal cuttings taken at Maasland, The Netherlands, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tamar True Pink’. These characteristics in combination distinguish ‘Tamar True Pink’ as a new and distinct Impatiens cultivar: 
     1. Light pink-colored flowers with red purple “eye”. 
     2. Very freely flowering habit with flowers positioned above or beyond the foliage. 
     3. Upright, somewhat outwardly spreading, rounded, uniform and compact plant habit. 
     4. Freely branching growth habit. 
     5. Dark green leaves. 
     In side-by-side comparisons conducted by the Inventor in Maasland, The Netherlands, plants of the new Impatiens differ from plants of the male parent, the cultivar Tahiti, in the following characteristics: 
     1. Plants of the new Impatiens are more compact than plants of the cultivar Tahiti. 
     2. Plants of the new Impatiens flower earlier than plants of the cultivar Tahiti. 
     3. Plants of the new Impatiens are more freely flowering than plants of the cultivar Tahiti. 
    
    
     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 actual colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Tamar True Pink’ grown in a 12.5-cm container. 
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The cultivar Tamar True Pink hs not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, water status and fertility level, without, however, any variance in genotype. The following observations and measurements describe plants grown in Maasland, The Netherlands, during the early autumn, under commercial practice in a glass-covered greenhouse. Plants used in the following description were about 10 to 12 weeks old from planting rooted cuttings and grown in 12.5-cm containers with one plant per container. 
     In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. 
     Botanical classification:  Impatiens hawkeri  cultivar Tamar True Pink. 
     Commercial classification: New Guinea Impatiens cultivar Tamar True Pink. 
     Parentage: 
       Male parent.—Impatiens hawkeri  cultivar Tahiti, disclosed in U.S. Plant Pat. No. 8,601. 
       Female parent.— Inventor&#39;s proprietary  Impatiens hawkeri  selection code number 942102, not patented. 
     Propagation: 
       Type cutting.— Terminal cuttings. 
       Time to initiate roots.— Summer: About 5 to 7 days at 19 to 20° C. Winter: About 6 to 8 days at 19 to 20° C. 
       Time to produce a rooted cutting or liner.— Summer: About 14 to 19 days at 19 to 20° C. Winter: About 14 to 21 days at 19 to 20° C. 
       Root description.— Numerous, fibrous, and freely branching. 
     Plant description:
