Coleus plant named ‘UF16-88-9’

‘UF16-88-9’ is a new Coleus plant with novel characteristics that include a vigorous compact mounded growth habit, an excellent heat tolerance, and consistent maroon leaves with bright pink centers. It has superior stability in foliage color in both sun and shade conditions, maintaining stable color in all conditions. ‘UF16-88-9’ 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: ‘UF16-88-9’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of Coleus plant named ‘UF16-88-9’. ‘UF16-88-9’ originated from an open-pollination conducted in May-November 2015 in Gainesville, Fla. between the female Coleus plant ‘UF15-76-1’ (unpatented) and an unknown male Coleus plant. A single seedling was chosen in May 2016 for further asexual propagation in Gainesville, Fla.

‘UF16-88-9’ has been reproduced asexually for over 18 months through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF16-88-9’ was first propagated asexually by meristem tip cuttings in May 2016 in Gainesville, Fla., and has remained true-to-type since that time.

‘UF16-88-9’ has maroon lance-shaped leaves with deep pink centers that are much longer than they are wide; whereas, ‘UF15-76-1,’ the female parent, has lance-shaped leaves that are colored deep maroon with green accents. ‘UF16-88-9’ has an extremely vigorous well-branched mounded habit; whereas ‘UF15-76-1’ is vigorous, but more upright in habit with less lateral branching.

‘UF16-88-9’ has similar maroon and pink foliage color to the commercial variety Velveteen® (‘UF13-6-11,’ unpatented), but ‘UF16-88-9’ is not as upright and rangy in habit. ‘UF16-88-9’ has lance-shaped leaves and mounded habit similar to the commercial varieties ‘UF12-82-3’ (U.S. Plant Pat. No. 27,288) and ‘UF12-73-5’ (U.S. Plant Pat. No. 27,499); however, ‘UF12-82-3’ and ‘UF12-73-5’ do not have the maroon and pink foliage color of ‘UF-16-88-9.’

SUMMARY OF THE INVENTION

The following are characteristics of ‘UF16-88-9’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF16-88-9’ has a novel, vigorous, compact upright growth habit, an excellent heat tolerance, and consistent maroon and bright pink lance-shaped leaves 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 ‘UF16-88-9’ 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. ‘UF16-88-9’ 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. 2—Shows the growth habit, form, and foliage of ‘UF16-88-9.’

FIG. 3—shows a close-up of the foliage of ‘UF16-88-9.’

 DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘UF16-88-9’. 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.

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.
