Coleus plant named ‘UF13-26-7’

Abstract

‘UF13-26-7’ is a new coleus plant distinguished by having consistent, bright orange-bronze colored leaves, a vigorous but compact growth habit, and no flowering characteristics, as disclosed herein.

Description

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

Cultivar denomination: ‘UF13-26-7’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of coleus plant named ‘UF13-26-7’. ‘UF13-26-7’ originated from an open pollination conducted in May-November 2012 in Gainesville, Fla. between the female coleus plant ‘UF12-29-4’ (unpatented) and an unknown male coleus plant. A single seedling was chosen in May 2013 for further asexual propagation in Gainesville, Fla.

‘UF13-26-7’ has been reproduced asexually for over two years through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF13-26-7’ was first propagated asexually by meristem tip cuttings in May 2013 in Gainesville, Fla., and has remained true-to-type since that time.

‘UF13-26-7’ has not been made publicly available more than one year prior to the filing date of this application.

When compared to the female parent ‘UF12-29-4’, ‘UF13-26-7’ has large, orange-bronze leaves and a compact branched habit, while ‘UF12-29-4’ has slightly smaller leaves colored deep bronze with a more upright plant habit and less lateral branching.

When ‘UF13-26-7’ is compared to the commercial cultivar ‘UF09-8-87’ (unpatented; trade name Keystone Kopper®), both plants have orange-bronze foliage color and purple stems, however the leaves of ‘UF13-26-7’ are larger and more brightly colored in both sun and shade conditions. ‘UF13-26-7’ also has a more vigorous growth habit and has not been observed to flower, whereas ‘UF09-8-87’ flowers profusely.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘UF13-26-7’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF13-26-7’ has a combination of a novel, vigorous, compact, upright growth habit, excellent heat tolerance, and consistent bright orange-bronze colored leaves. ‘UF13-26-7’ has superior stability in foliage color in both sun and shade conditions, maintaining stable color in all conditions. ‘UF13-26-7’ 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. Due to the plant never being observed to produce flowers in Gainesville, Fla., ‘UF13-26-7’ 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. FIGS. 2 and 3 were taken of plants grown for nine weeks from unrooted cuttings that were pinched once at four weeks after stick and grown five additional weeks in November 2014-January, 2015 in a poly-covered plastic greenhouse in Gainesville, Fla.

FIG. 1—shows the pedigree of the claimed plant.

FIG. 2—shows the growth habit, form, and foliage of the claimed plant.

FIG. 3—shows a close-up of the foliage.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘UF13-26-7’. The detailed description was obtained using eight-week-old plants grown from uprooted cuttings in November-January of 2015 in a poly-covered plastic greenhouse in Gainesville, Fla. The plants were pinched four weeks after cuttings were stuck, then grown in 1-gallon pots for approximately five additional weeks. Color references are to The R.H.S.

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.
