Title: Gaura plant named ‘Baltincite’

Description:
Latin name of genus and species of plant claimed:  Gaura lindheimeri.    
   Variety denomination: ‘Baltincite’. 
   BACKGROUND OF THE INVENTION 
   The present invention relates to a new and distinct cultivar of  Gaura  plant botanically known as  Gaura lindheimeri  and hereinafter referred to by the cultivar name ‘Baltincite’. 
   The new cultivar originated in a controlled breeding program in Elburn, Ill. during February 2004. The objective of the breeding program was the development of  Gaura  cultivars that continuously flower with attractive flower coloration, dark green-colored foliage, and a well-branched, upright to semi-upright habit in the garden. 
   The new  Gaura  cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary  Gaura lindheimeri  breeding selection designated 0044-A2, not patented, characterized by its dark pink-colored flowers, dark green-colored foliage, and moderately vigorous, semi-upright growth habit. The male (pollen) parent of the new cultivar is the proprietary  Gaura lindheimeri  breeding selection designated 0017-A1-B2-A2-2, not patented, characterized by its white-colored flowers, medium green-colored foliage, and moderately vigorous, semi-upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during June 2005 in a controlled environment at Elburn, Ill. 
   Asexual reproduction of the new cultivar by terminal stem cuttings since June 2005 at Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation. 
   SUMMARY OF THE INVENTION 
   The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Baltincite’ as a new and distinct cultivar of  Gaura  plant:
         1. White-colored flowers;   2. Dark green-colored foliage; and   3. Moderately vigorous, upright to semi-upright growth habit in the garden.       

   Plants of the new cultivar differ from plants of the female parent primarily in flower color and plant height. The new cultivar is shorter than the female parent. Plants of the new cultivar differ from plants of the male parent primarily in foliage color and branching characteristic. The new cultivar has more branches than the male parent. 
   Of the many commercially available  Gaura  cultivars, the most similar in comparison to the new cultivar is ‘Whirling Butterflies’, not patented. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Whirling Butterflies’ in at least the following characteristics:
         1. Plants of the new cultivar begin to flower approximately 7 days earlier than plants of ‘Whirling Butterflies’;   2. Plants of the new cultivar have more inflorescences per plant with fully open flowers than plants of ‘Whirling Butterflies’; and   3. Plants of the new cultivar have a glabrous upper leaf surface texture compared to a pubescent upper leaf surface texture for plants of ‘Whirling Butterflies’.       

   
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Baltincite’. The plants were grown in 4.5 inch pots for 6 weeks in a greenhouse at West Chicago, Ill. Plants were given one pinch at transplant.

       FIG. 2  illustrates a close-up view of an individual flower of ‘Baltincite’. 
   

   DETAILED BOTANICAL DESCRIPTION 
   The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype. 
   The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Apr. 29, 2008 between 9:00 a.m. and 11:00 a.m. under natural light conditions in West Chicago, Ill. 
   The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 4.5 inch pots for 6 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
