Title: Coleus plant named ‘UF08-5-10’

Description:
Latin name of the genus and species of the plant claimed:  Solenostemon scutellarioides.    
     Cultivar denomination: ‘UF08-5-10’. 
     BACKGROUND OF THE INVENTION 
     The invention relates to a new and distinct cultivar of coleus plant named ‘UF08-5-10’. ‘UF08-5-10’ originated from an open pollination conducted in May-November 2007 in Gainesville, Fla. between the female coleus plant ‘UF07-10-22’ (unpatented) and an unknown male coleus plant. The first asexual reproduction was performed in May 2008 in Gainesville, Fla. by vegetative stem cuttings using a single seedling (see  FIG. 1  for pedigree). 
     ‘UF08-5-10’ has been reproduced asexually for over 5 years through vegetative stem cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. 
     ‘UF08-5-10’ has not been made publicly available more than one year prior to the filing date of this application. 
     When ‘UF08-5-10’ is compared to the female parent ‘UF07-10-22’, ‘UF08-5-10’ has large, golden yellow, lance-shaped leaves with lime green markings and a purple stem, while ‘UF07-10-22’ has lance-shaped leaves colored dull maroon and green with bright yellow margins. When ‘UF08-5-10’ is compared to the most comparable commercial cultivar ‘Yellow Dragon’, both cultivars have yellow lance-shaped leaves with purple stems. However, ‘Yellow Dragon’ leaves are more highly lobed with round lobe tips, while leaves of ‘UF08-5-10’ have fewer lobes that are pointed at the tip. 
     SUMMARY OF THE INVENTION 
     The following are the most outstanding and distinguishing characteristics of ‘UF08-5-10’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF08-5-10’ has a consistent, vigorous, spreading growth habit, late season flowering, excellent heat tolerance, and novel golden yellow, lance-shaped leaves with distinct purple stems, characteristics that are significantly different than other coleus plants. It has superior stability in foliage color in both sun and shade conditions, maintaining stable color in all conditions. It has a vigorous, spreading growth habit with excellent lateral branching when grown as a stock plant, thus providing ample vegetative propagules for producers. This plant has not been observed to set a significant number of flowers in any trial to date, thus it is desirable for long-season performance in the landscape, as coleus plants that set seed usually experience late-season leaf drop.

     DETAILED BOTANICAL DESCRIPTION 
     The following detailed description sets forth the distinctive characteristics of coleus variety ‘UF08-5-10’. The detailed description was obtained using 9-week-old plants from cuttings growing in a glass greenhouse in Gainesville, Fla. in late fall 2013. The plants were pinched 2 weeks after cuttings were rooted, then grown in 1-gallon pots for approximately 9 weeks. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 2007 5th Edition.

       Flowers and seeds: Flowers and seeds have not been observed.   Fruit/seed set: Fruit/seed not observed.   Disease and insect resistance: Disease and insect resistance is typical of the species, thus no claims are made of any superior disease or insect resistance with this cultivar. The most common insect pests observed on this plant in Gainesville, Fla. have been long-tailed or citrus mealybugs ( Pseudococcus  sp.), which occur on older stock plant material held in the greenhouse for over 3-4 months. Impatiens Necrotic Spot Virus ( Bunyaviridae ) has also been observed in plants confined in greenhouses with mixed crops (peppers) infected with Western flower thrips ( Frankliniella occidentalis ). The most common pathogen of this species in the U.S. is downy mildew ( Peronospora lamii ). This pathogen has been observed in stock materials grown closely together in cooler growing seasons.
