Title: Angelonia Plant Named &#39;Ansublu021&#39;

Description:
Botanical designation:  Angelonia angustifolia.    
     Cultivar denomination: ‘ANSUBLU021’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Angelonia  plant, botanically known as  Angelonia angustifolia  and hereinafter referred to by the name ‘Ansublu021’. 
     The new  Angelonia  plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to create new freely-flowering  Angelonia  plants with attractive flower coloration and long flowering period. 
     The new  Angelonia  plant originated from a cross-pollination made by the Inventor during the summer of 2015 in Dresden, Germany of two unnamed proprietary selections of  Angelonia angustifolia , not patented. The new  Angelonia  plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Dresden, Germany during the summer of 2016. 
     Asexual reproduction of the new  Angelonia  plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, 
     Germany since the summer of 2016 has shown that the unique features of this new  Angelonia  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Angelonia  have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ansublu021’. These characteristics in combination distinguish ‘Ansublu021’ as a new and distinct  Angelonia  plant:
         1. Broadly upright plant habit.   2. Vigorous growth habit.   3. Freely branching habit.   4. Relatively long and thick flowering stems.   5. Freely flowering habit.   6. Large dark purple to purple violet-colored flowers with white-colored centers.   7 Suitable for cut flower production with good postproduction longevity.       

     Plants of the new  Angelonia  differ from plants of the parent selections primarily in plant and flowering habit as plants of the new  Angelonia  are more freely branching and freely flowering than plants of the parent selections. 
     Plants of the new  Angelonia  can be compared to plants of  Angelonia hybrida  ‘Ansublu’, disclosed in U.S. Plant Pat. No. 29,158. In side-by-side comparisons, plants of the new  Angelonia  and ‘Ansublu’ differ primarily in the following characteristics:
         1. Plants of the new  Angelonia  are slightly shorter than plants of ‘Ansublu’.   2. Plants of the new  Angelonia  flower slightly later than plants of ‘Ansublu’.   3. Plants of the new  Angelonia  and ‘Ansublu’ differ in flower color as plants of the new  Angelonia  have purple to purple violet-colored flowers with white-colored centers whereas plants of ‘Ansublu’ have violet-colored flowers with white-colored centers.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying colored photograph illustrates the overall appearance of the new  Angelonia  plant 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  Angelonia  plant. 
       The photograph ( FIG. 1  of 1) is a side perspective view of a typical flowering plant of ‘Ansublu021’ grown in a container. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     Plants used for the aforementioned photograph and the following observations, measurements and values were grown during the summer and autumn in 19-cm containers in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial  Angelonia  production. During the production of the plants, day temperatures were at a minimum of 20° C., night temperatures were at a minimum of 16° C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were pinched two times, two and six weeks after planting rooted young plants. Plants were six months old when the description was taken and seven months old when the photograph was taken. 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.
