Abstract

‘UF16-72-8’ is a new coleus plant with novel characteristics that include a vigorous compact mounded growth habit, an excellent heat tolerance, and consistent bright green leaves with maroon venation and pink accents. It has superior stability in foliage color in both sun and shade conditions, maintaining stable color in all conditions. ‘UF16-72-8’ has not been observed to produce flowers in any trial we have conducted to date, and thus it has long season performance as an annual plant in the landscape until late Fall.

Description

Latin name of the genus and species of the plant claimed: Plectranthus scutellarioides.
Cultivar denomination: ‘UF16-72-8’.
BACKGROUND OF THE INVENTION
The invention relates to a new and distinct cultivar of coleus plant named ‘UF16-72-8’. ‘UF16-72-8’ originated from an open-pollination conducted in May-November 2015 in Gainesville, Fla. between the female coleus plant ‘UF15-95-1’ (unpatented) and an unknown male coleus plant. A single seedling was chosen in May 2016 for further asexual propagation in Gainesville, Fla.
‘UF16-72-8’ has been reproduced asexually for over 18 months through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF16-72-8’ was first propagated asexually by meristem tip cuttings in May 2016 in Gainesville, Fla., and has remained true-to-type since that time.
‘UF16-72-8’ has large dark green leaves with distinct maroon venation and pink accents leaves; whereas, ‘UF15-95-1’, the female parent, has leaves colored dark maroon with green margins. ‘UF16-72-8’ has moderate vigor and well-branched upright habit; whereas, ‘UF15-95-1’ is vigorous, but more mounded in habit with more lateral branching.
‘UF16-72-8’ has similar foliage color and patterning to that of the commercial variety ‘Mainstreet Abbey Road’ (‘UF12-46-2’, unpatented), but ‘UF16-72-8’ leaves have hints of pink and its leaf venation pattern is more consistent in sun and shade than that of ‘UF12-46-2’. Further, ‘UF16-72-8’ is not as rangy and vigorous as ‘UF12-46-2’, and thus ‘UF16-72-8’ is more compact and refined in habit.
SUMMARY OF THE INVENTION
The following are characteristics of ‘UF16-72-8’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF16-72-8’ has a novel, vigorous, compact upright growth habit, an excellent heat tolerance, and consistent bright green leaves with purple venation 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. When ‘UF16-72-8’ is grown as a stock plant, it has a vigorous but compact upright growth habit with excellent lateral branching, and thus provides ample vegetative propagules for producers. ‘UF16-72-8’ has not been observed to produce flowers in any trial we have conducted to date in Gainesville, Fla., and thus it is desirable for long-season performance in the landscape.
BRIEF DESCRIPTION OF THE DRAWINGS
This new coleus plant is illustrated by the accompanying photographs, which show the plant's form and foliage. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs in FIGS. 2 and 3 are of plants grown for 11 weeks from unrooted cuttings in May-July 2017 in a poly-covered plastic greenhouse in Gainesville, Fla.
FIG. 1—Shows the pedigree of ‘UF16-72-8’.
FIG. 2—Shows the growth habit, form, and foliage of ‘UF16-72-8’.
FIG. 3—Shows a close-up of the foliage of ‘UF16-72-8’.
DETAILED BOTANICAL DESCRIPTION
The following detailed description sets forth the distinctive characteristics of ‘UF16-72-8’. The detailed description was obtained using 10-week-old plants grown from unrooted cuttings in May-July 2017 in a poly-covered plastic greenhouse in Gainesville, Fla. The plants were propagated in mist for 10 days after cuttings were stuck and then grown in 1-gallon pots for approximately 9.5 additional weeks. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 2007 5th Edition.

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.
