USPP25650P3 - Coleus plant named ‘UF12-87-9’ - Google Patents

Abstract

‘UF12-87-9’ is a new coleus plant distinguished by having consistent deep red leaves with distinct lime green margins, novel growth habit, and desirable late-flowering characteristics, as disclosed.

Description

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

Cultivar denomination: ‘UF12-87-9’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of coleus plant named ‘UF12-87-9’. ‘UF12-87-9’ originated from an open pollination conducted in May-November 2011 in Gainesville, Fla. between the female coleus plant ‘UF11-74-24’ (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).

‘UF12-87-9’ has been reproduced asexually for over one year through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations.

‘UF12-87-9’ has not been made publicly available more than one year prior to the filing date of this application.

When ‘UF12-87-9’ is compared to the female parent ‘UF11-74-24’, ‘UF12-87-9’ has large, deep red leaves with distinct lime green margins, while ‘UF11-74-24’ has smaller leaves colored bright red with bright yellow margins.

When ‘UF12-87-9’ is compared to the commercial cultivar Frilly Milly™ ‘UF04-47-64’ (commercial, unpatented), both plants have red foliage, but ‘UF12-87-9’ has a brighter, more contrasting lime green leaf margin, while Frilly Milly™ ‘UF04-47-64’ has more irregular and darker green contrasting foliage color. ‘UF12-87-9’ also has a more vigorous and more spreading growth habit with more lateral branching than Frilly Milly™ ‘UF04-47-64’.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘UF12-87-9’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF12-87-9’ has a combination of novel vigorous spreading growth habit, late season flowering, excellent heat tolerance, and consistent deep red leaves with distinct lime green margins that is 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 spreading growth habit with excellent lateral branching when grown as a stock plant, thus providing ample vegetative propagules for producers. This plant has not been observed to set a significant number of flowers in any trial to date, thus it is desirable for long-season performance in the landscape, as coleus plants that set seed usually experience late-season leaf drop.

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 were taken from 3-month-old plants grown from cuttings in 1-gallon pots during December 2012-March 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 ‘UF12-87-9’. The detailed description was obtained using 3-month-old plants from cuttings, growing in a glass greenhouse in Gainesville, Fla. in early spring 2013. The plants were pinched 2 weeks after cuttings were rooted, then grown in 1-gallon pots for approximately 10 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 US is downy mildew (Pernonspora lamii). This pathogen has been observed in stock materials grown closely together in cooler growing seasons.
