plant named ‘UF09-8-37’

Abstract

‘UF09-8-37’ is a new coleus plant distinguished by having consistent lance shaped orange leaves, novel and vigorous growth habit, as disclosed herein.

Description

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

Cultivar denomination: ‘UF09-8-37’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of coleus plant named ‘UF09-8-37’. ‘UF09-8-37’ originated from an open pollination conducted in May-November 2008 in Gainesville, Fla. between the female coleus plant ‘UF08-29-1’ (unpatented) and an unknown male coleus plant. The first asexual reproduction was performed in May 2009 in Gainesville, Fla. by vegetative stem cuttings using a single seedling (see FIG. 1 for pedigree).

‘UF09-8-37’ has been reproduced asexually for over one year through vegetative stem cuttings and has been found to retain its distinctive characteristics through successive asexual propagations.

‘UF09-8-37’ has not been made publicly available more than one year prior to the filing date of this application.

When ‘UF09-8-37’ is compared to the female parent ‘UF08-29-1’ (unpatented), ‘UF09-8-37’ has deeply lobed, lance-shaped bronze/orange leaves and has a lateral spreading plant architecture. By contrast, ‘UF08-29-1’ is an upright, non-spreading plant with bronze-orange leaves that are serrated and typical of the species.

When ‘UF09-8-37’ is compared to the commercial cultivar ‘Spitfire’ ‘UF07-24-5’ (commercial, unpatented), both plants have lance-shaped, bronze-orange foliage, but leaves of ‘UF09-8-37’ are much larger in size and have deeper, more stable orange color in both sun and shade conditions. ‘UF09-8-37’ also has a more vigorous and more spreading growth habit with more lateral branching than ‘Spitfire’ ‘UF07-24-5’.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘UF09-8-37’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF09-8-37’ has a novel, vigorous, spreading growth habit, late season flowering, excellent heat tolerance, and consistent, lance-shaped orange leaves that are significantly different than other coleus plants. It has superior stability of 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.

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 9-week-old plants grown from cuttings in 1-gallon pots during September-November 2013 in greenhouses in Gainesville, Fla.

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

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of coleus variety ‘UF09-8-37’. 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.

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.
