Title: Coleus plant named ‘South of the Border’

Description:
Botanical classification/cultivar designation: Coleus×hybrida South of the Border. 
     BACKGROUND OF THE INVENTION 
     The present Invention relates to a new and distinct cultivar of Coleus plant, botanically known as  Solenostemon scutellarioides , and hereinafter referred to by the cultivar name South of the Border. 
     The new cultivar was discovered by the Inventor in a controlled environment in Waynesville, N.C. as a naturally-occurring branch mutation of a the  Solenostemon scutellarioides  cultivar Aurora, not patented. The new Coleus was observed within a population of plants of the cultivar Aurora in July, 2000. This branch mutation was selected on the basis of its unique leaf coloration. 
     Asexual reproduction of the new cultivar by terminal cuttings taken in Waynesville, N.C. since July, 2000, has shown that the unique features of this new Coleus are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the cultivar South of the Border have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘South of the Border’. These characteristics in combination distinguish ‘South of the Border’ as a new and distinct cultivar: 
     1. Upright and mounded plant habit. 
     2. Pale yellow and green bi-colored leaves. 
     3. Numerous small violet blue-colored flowers arranged on terminal verticillasters. 
     Plants of the new Coleus are most similar to plants of the parent, the cultivar Aurora. Plants of the new Coleus differ from plants of the parent selection primarily in foliage color as plants of the cultivar Aurora have upper and lower leaf surfaces strongly flushed with red purple and red purple-colored venation. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored 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 Coleus. 
     The photograph at the top of the sheet comprises a side perspective view of typical plant of ‘South of the Border’ grown in a container. 
     The photograph at the bottom of the sheet comprises a close-up view of typical leaves and a typical inflorescence of ‘South of the Border’. 
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The cultivar South of the Border has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. 
     The aforementioned photographs, following observations and measurements describe plants grown during the winter and spring in Encinitas, Calif., in an outdoor nursery and under conditions which approximate commercial production cultural and environmental conditions. Plants were about 14 weeks from cuttings and were grown in one-gallon containers. During the production of the plants, day temperatures averaged 24° C. and night temperatures averaged 19° C. 
     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.
