Abstract

‘UF22-146-3’ is a new Coleus plant, selected for having a combination of desirable traits that make it well-suited for use as an annual plant in the summer landscape. ‘UF22-146-3’ was selected for its consistent and novel bright reddish brown to dark red foliage color and for its consistent compact and mounding habit and vigorous growth rate in the greenhouse and landscape. ‘UF22-146-3’ has large, lance-shaped leaves that are twice as long as they are wide. ‘UF22-146-3’ maintains its foliage colors and leaf patterns in both sun and shade until the end of the garden season. ‘UF22-146-3’ has a highly branched and spreading form, growing wider than it does tall.

Description

Genus and species: Coleus scutellarioides.

Cultivar denomination: ‘UF22-146-3’.

BACKGROUND OF THE NEW CULTIVAR

The invention relates to a new and distinct cultivar of Coleus plant named ‘UF22-146-3’. The new cultivar ‘UF22-146-3’ originated from an open pollination conducted in May-November 2021 in Citra, Florida, between the female Coleus plant ‘UF21-66-2’ (unpatented) and an unknown male Coleus plant. A single seedling was chosen in May 2022 for further asexual propagation in Gainesville, Florida.

The new cultivar ‘UF22-146-3’ has been reproduced asexually for over 11 months through vegetative meristem tip cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF22-146-3’ was first propagated asexually by vegetative meristem tip cuttings in May 2022 in Gainesville, Florida, and has remained true-to-type since that time.

Plant Breeder's Rights for the new cultivar ‘UF22-146-3’ have not been applied for, and ‘UF22-146-3’ has not been made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The new cultivar ‘UF22-146-3’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment and cultural practices such as temperature, light intensity, fertilization, irrigation, and application of plant growth regulators without any change in genotype.

The new cultivar ‘UF22-146-3’ was selected for its novel reddish brown to dark red foliage color and for its consistent, compact, and mounding habit in greenhouse-grown pots and landscape planting. ‘UF22-146-3’ is exceptional because it'maintains this novel color in both sun and shade. These characteristics allow the plant to have utility in mass outdoor ground plantings, or in containers as a specimen in small gardens.

The following are the most outstanding and distinguishing characteristics of ‘UF22-146-3’ when grown under normal horticultural practices in Gainesville, Florida: (1) ‘UF22-146-3’ has the combination of compact and mounding habit and spreading growth form, excellent heat tolerance, and consistent bright reddish brown to dark red foliage color that is significantly different than other Coleus plants; (2) it has superior stability in foliage color in both sun and shade conditions, and it has a vigorous growth habit with excellent lateral branching, making it suitable for propagators and producers; and (3) ‘UF22-146-3’ has been observed to have long-season performance in landscape trials in Gainesville, Florida.

When compared to the female parent ‘UF21-66-2’, ‘UF22-146-3’ has large, lance-shaped leaves that are twice as long as they are wide, whereas ‘UF21-66-2’ has large leaves that are equally as long as they are wide. Additionally, ‘UF'22-146-3’ has novel bright reddish brown to dark red colored leaves with yellow green accents and purplish red areas around the veins, whereas ‘UF21-66-2’ has deep crimson colored leaves and chartreuse margins and crimson netted patterning. ‘UF22-146-3’ has a vigorous compact and mounding growth habit and a spreading form that is well-branched, whereas ‘UF21-66-2’ is less vigorous, and more upright in habit with less lateral branching and a less spreading form.

DESCRIPTION OF THE FIGURES

This new Coleus cultivar ‘UF22-146-3’ 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 from plants grown eleven weeks from unrooted cuttings in September-December 2022 in a glass-covered greenhouse in Gainesville, Florida.

FIG. 1 shows the pedigree of the new Coleus cultivar ‘UF22-146-3’ as is shown and described herein, wherein the cultivar ‘Sedona’ has been patented as U.S. Plant Pat. No. 14,790 P2 (now expired);

FIG. 2 shows the growth habit, form, and foliage of the new Coleus cultivar; and

FIG. 3 shows a close-up view of the foliage of the new Coleus cultivar.

DETAILED BOTANICAL DESCRIPTION OF THE CULTIVAR

Foliage color was determined under full sun conditions in the middle of the day in a glass-covered greenhouse. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 2007 5th Edition. Coleus leaves are rarely one solid color but encompass hues, shades and tints, and color patterns differ from one genotype to another due to varying levels of variegation. The following detailed description of ‘UF22-146-3’ was obtained using eleven-week-old plants grown from unrooted cuttings in September-December 2022 in a glass-covered greenhouse in Gainesville, Florida. The plants were propagated in mist for ten days after cuttings were stuck, pinched, then grown in one-gallon pots for approximately nine and a half additional weeks.
