Abstract:
A new and distinct cultivar of  Lantana  plant named ‘Apricot Sunrise’, characterized by its low growing, spreading growth habit; leathery, scabrous medium green foliage; continuous flowering; and yellow flower buds that open to yellow with a darker yellow-orange center and age to apricot pink with an orange center.

Description:
Genus and species of plant claimed:  Lantana  sp. 
     Variety denomination: ‘Apricot Sunrise’. 
     BACKGROUND OF THE INVENTION 
     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 ‘Apricot Sunrise’. 
     The new  Lantana  plant originated from a controlled cross between  Lantana  sp. ‘Chapel Hill Gold’ (U.S. Plant Pat. No. 21,539) and an unnamed seedling of  Lantana camara  known to the inventor as  Lantana camara  DIO (not patented) as part of a planned breeding program to develop low growing, continuously flowering  lantanas  with dark green foliage. The cultivar ‘Apricot Sunrise’ originated and was discovered in a cultivated environment in a greenhouse in Watkinsville, Ga. 
     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 
     Plants of the new cultivar ‘Apricot Sunrise’ 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. 
     The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Apricot Sunrise’. These characteristics in combination distinguish ‘Apricot Sunrise’ as a new and distinct cultivar: 1. Low growing, spreading growth habit; 2. Leathery, scabrous medium green foliage; 3. Continuous flowering; and 4. Yellow flower buds that open to yellow with a darker yellow-orange center and age to apricot pink with an orange center. There are no other cultivars of  Lantana  with this combination of characteristics known to the inventor. 
     Plants of the new  Lantana  ‘Apricot Sunrise’ differ from plants of the female parent, ‘Chapel Hill Gold’, primarily in flower color and foliage color, as plants of ‘Chapel Hill Gold’ have bright golden yellow flower buds and flowers and dark green foliage, whereas plants of ‘Apricot Sunrise’ have yellow flower buds that open to yellow with a darker yellow-orange center and age to apricot pink with a orange center and medium green foliage. Plants of the new  Lantana  ‘Apricot Sunrise’ differ from plants of the male parent, an unnamed seedling known to the inventor as  Lantana  DIO, primarily in flower color, foliage color, and growth habit, as plants of the male parent have flowers that remain light orange, dark green foliage, and a loose, rounded growth habit, whereas plants of ‘Apricot Sunrise’ have yellow flower buds that open to yellow with a darker yellow-orange center and age to apricot pink with a orange center, medium green foliage, and an overall wider, lower, spreading growth habit. 
     ‘Apricot Sunrise’ can be compared to the cultivar ‘Balandimpea’ (U.S. Plant Pat. No. 19,358), but differs in the growth habit, foliage, and floral characteristics. ‘Apricot Sunrise’ has a low growing, spreading growth habit, whereas ‘Balandimpea’ has a moderately vigorous, semi-upright growth habit. ‘Apricot Sunrise’ has smaller, medium green mature foliage, whereas ‘Balandimpea’ has larger, darker green mature foliage. ‘Apricot Sunrise’ has mature flowers that are apricot pink with an orange center, whereas ‘Balandimpea’ has mature flowers that are peach-colored. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       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.
