Abstract:
A new and distinct cultivar of  Lantana  plant named ‘Sunny Side Up’, characterized by its low growing, spreading growth habit; leathery, scabrous dark green foliage; continuous flowering; and yellow flower buds that open to yellow with a darker golden-yellow center and age to white with a yellow center.

Description:
GENUS AND SPECIES OF PLANT CLAIMED 
       [0001]      Lantana  sp. 
       VARIETY DENOMINATION 
       [0002]    ‘Sunny Side Up’ 
       BACKGROUND OF THE INVENTION 
       [0003]    The present invention relates to a new and distinct cultivar of  Lantana  plant, botanically known as  Lantana  sp., and hereinafter referred to by the cultivar name ‘Sunny Side Up’. 
         [0004]    The new  Lantana  plant originated from a controlled cross between  Lantana  sp. ‘Chapel Hill Gold’ (plant patent allowed) and an unnamed selection of  Lantana camara  (not patented) as part of a planned breeding program to develop low growing, continuously flowering  lantanas  with dark green foliage. The cultivar ‘Sunny Side Up’ originated and was discovered in a cultivated environment in Watkinsville, Ga. 
         [0005]    Asexual reproduction of the new cultivar by stem cuttings in Watkinsville, Ga. has shown that all the unique features of this new  Lantana , as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation. 
       SUMMARY OF THE INVENTION 
       [0006]    Plants of the new cultivar ‘Sunny Side Up’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype. 
         [0007]    The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Sunny Side Up’. These characteristics in combination distinguish ‘Sunny Side Up’ as a new and distinct cultivar: 1. Low growing, spreading growth habit; 2. Leathery, scabrous dark green foliage; 3. Continuous flowering; and 4. Yellow flower buds that open to yellow with a darker golden-yellow center and age to white with a yellow center. 
         [0008]    Plants of the new  Lantana  ‘Sunny Side Up’ differ from plants of the female parent, ‘Chapel Hill Gold’, primarily in flower color, as plants of ‘Chapel Hill Gold’ have bright golden yellow flower buds and flowers, whereas plants of ‘Sunny Side Up’ have yellow flower buds that open to yellow with a darker golden-yellow center and age to white with a yellow center. Plants of the new  Lantana  ‘Sunny Side Up’ differ from plants of the male parent, an unnamed selection, primarily in flower color, foliage color, and growth habit, as plants of the male parent have white flower buds that open to solid white flowers, medium green foliage, and a smaller, rounded growth habit, whereas plants of ‘Sunny Side Up’ have yellow flower buds that open to yellow with a darker golden-yellow center and age to white with a yellow center, dark green foliage, and an overall wider, lower, spreading growth habit. 
         [0009]    Plants of the new cultivar ‘Sunny Side Up’ can be compared to plants of the cultivar ‘LCBCW’ (not patented). However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of the new cultivar ‘Sunny Side Up’ differed from plants of the cultivar ‘LCBCW’ in the following characteristics: 1. Plants of the new cultivar ‘Sunny Side Up’ had darker green, thicker, more scabrous foliage than plants of the cultivar ‘LCBCW’; 2. Plants of the new cultivar ‘Sunny Side Up’ had brighter flower color and larger flowers than plants of the cultivar ‘LCBCW’; and 3. Plants of the new cultivar ‘Sunny Side Up’ produced a finished size saleable plant quicker than plants of the cultivar ‘LCBCW’. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0010]    The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of the new  Lantana , showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Lantana.
