Title: Lagerstroemia plant named &#39;sweet macchiato&#39;

Description:
Botanical classification:  Lagerstroemia indica.    
     Varietal denomination: ‘Sweet Macchiato’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of the ornamental flowering shrub  Lagerstroemia indica  commonly known as crape myrtle, and hereafter referred to by the cultivar name ‘Sweet Macchiato’. 
       Lagerstroemia  ‘Sweet Macchiato’ originated from open-pollinated seed of  Lagerstroemia  ‘Whit VI’ U.S. Plant Pat. No. 14,438 collected by the inventor in the fall of 2010 at a cultivated area in Raleigh, N.C., USA. The new plant was grown out in a full-sun, loamy-sand field environment with water as needed and passed rigorous evaluations at the same nursery with goals for this program to produce improved, garden-worthy plants for the ornamental plant market of quality flower color and improved habit that would withstand cold temperatures. The single new plant meeting these criteria was originally assigned breeder code H10-02-28. 
     No plants of  Lagerstroemia  ‘Sweet Macchiato’ have been sold, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which may have been disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor. 
       Lagerstroemia  ‘Sweet Macchiato’ was first asexually propagated from a single select plant in 2012 by stem cuttings at a wholesale perennial nursery in Zeeland, Mich. The resultant asexually propagated plants have been found to be stable and true to type in successive generations of asexual reproduction. 
     SUMMARY OF THE INVENTION 
     Plants of the new crape myrtle cultivar  Lagerstroemia  ‘Sweet Macchiato’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as light-intensity, temperature light-intensity, available moisture and fertility without, however, any variance in genotype. 
     The following traits in combination have been consistently observed and are determined to make up some of the unique characteristics of ‘Sweet Macchiato’:
         1. Short rounded habit;   2. Ground hardy to at least USDA zone 6;   3. Glossy foliage emerges reddish mahogany and develops to a dark olive coloring;   4. Fragrant hot-pink flowers.       

     The nearest comparison crape myrtle varieties known to the inventor are: ‘Coral Filli’ U.S. Plant Pat. No. 14,317, ‘Rosey Carpet’ U.S. Plant Pat. No. 13,965, ‘Plum Magic’ U.S. Plant Pat. No. 23,518 and ‘Coral Magic’ U.S. Plant Pat. No. 23,922. Compared to ‘Coral Filli’ the new plant is shorter in habit and the flower color is more toward a lavender hue. Compared to ‘Rosey Carpet’ the new plant is taller and more mounded in habit, and the flower color is more in the lavender hue and slightly less pink. Compared to ‘Plum Magic’ the new plant is shorter and more mounded in habit, and the flower color is lighter in hue. Compared to ‘Coral Magic’ the new plant is significantly shorter in height and the petals are more in the lavender range. 
     Compared to the female parent, ‘Whit VI’, the new plant is significantly shorter and has flowers that are hot-pink colored rather than the height of over 400 cm with white flowers. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.

         FIG. 2  shows a close-up of the flowers. 
         FIG. 3  shows the habit of a three-year-old plant in mid-season flowering.
