Abstract

‘UF12-22-1’ is a new coleus plant distinguished by having consistent bright orange-bronze leaves with distinct red-magenta venation, and a vigorous but compact growth habit, as disclosed.

Description

Latin name of the genus and species of the plant claimed: Solenostemon scutellarioides.

Cultivar denomination: ‘UF12-22-1’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of coleus plant named ‘UF12-22-1’. ‘UF12-22-1’ originated from an open pollination conducted in May-November 2011 in Gainesville, Fla. between the female coleus plant ‘UF11-3-11’ (unpatented) and an unknown male coleus plant. A single seedling was chosen in May 2012 for further asexual propagation in Gainesville, Fla. (see FIG. 1 for pedigree).

‘UF12-22-1’ has been reproduced asexually for over one year through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF12-22-1’ was first propagated asexually by meristem tip cuttings in May, 2012 in Gainesville, Fla., and has remained true-to-type since that time.

‘UF12-22-1’ has not been made publicly available more than one year prior to the filing date of this application.

When compared to the female parent ‘UF11-3-11’, ‘UF12-22-1’ has large, orange-bronze leaves and a compact branched habit, while ‘UF11-3-11’ has slightly smaller leaves colored deep bronze with a more vigorous and upright plant habit.

When ‘UF12-22-1’ is compared to the commercial cultivar ‘Keystone Kopper’ ‘UF09-8-87’ (commercial, unpatented), both plants have orange-bronze foliage color and purple stems, although ‘UF12-22-1’ leaves are larger, and more brightly colored in both sun and shade conditions. ‘UF12-22-1’ also has a more vigorous growth habit than ‘Keystone Kopper’ ‘UF09-8-87’.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘UF12-22-1’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF12-22-1’ has a combination of a novel, vigorous, compact upright growth habit, excellent heat tolerance, and consistent bright orange-bronze 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. It has a vigorous but compact upright growth habit with excellent lateral branching when grown as a stock plant, thus providing ample vegetative propagules for producers. This plant is desirable for long-season performance in the landscape.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘UF12-22-1’. The detailed description was obtained using twelve-week-old plants grown in March-May, 2014 in a glass greenhouse in Gainesville, Fla. The plants were pinched 4 weeks after cuttings were rooted, then grown in 1-gallon pots for approximately 8 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.
