USPP35714P2 - Coleus plant named ‘UF22-127-1’ - Google Patents

Abstract

‘UF22-127-1’ 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. ‘UF22-127-1’ was selected for its consistent strong brown foliage color, and also for its fast growth rate and vigor in the greenhouse and landscape. ‘UF22-127-1’ has ruffled, highly lobed foliage that is predominantly strong brown with consistent yellowish green accents at the leaf margins. ‘UF22-127-1’ maintains these colors and patterns in both sun and shade. ‘UF22-127-1’ is upright in growth habit, but is highly branched and spreading in plant form, growing wider than it does tall.

Description

Genus and species: Coleus scutellarioides.

Cultivar denomination: ‘UF22-127-1’.

BACKGROUND OF THE NEW CULTIVAR

The invention relates to a new and distinct cultivar of Coleus plant named ‘UF22-127-1’. The new cultivar ‘UF22-127-1’ originated from an open pollination conducted in May-November 2021 in Citra, Florida, between the female Coleus plant ‘UF21-58-2’ (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 ‘UF22-127-1’ 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. ‘UF22-127-1’ 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 ‘UF22-127-1’ have not been applied for, and ‘UF22-127-1’ 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 ‘UF22-127-1’ 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 ‘UF22-127-1’ was selected for its strong brown-colored foliage combined with a novel ruffled leaf shape. ‘UF22-127-1’ is exceptional because it has excellent lateral branching and vigor when grown in the greenhouse and landscape. Normally, strong brown-colored Coleus plants will turn green and dull in color when grown in shade conditions; however, ‘UF22-127-1’ maintains consistent strong brown color in both sun and shade with only slight green accents towards the leaf margins.

The following are the most outstanding and distinguishing characteristics of ‘UF22-127-1’ when grown under normal horticultural practices in Gainesville, Florida: (1) ‘UF22-127-1’ has the combination of vigorous, upright growth habit and spreading plant form, excellent heat tolerance, and consistent strong brown colored leaves with yellowish green accents at the leaf margins; (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; (3) it is highly branched and spreading in plant form, growing wider than it does tall; and (4) ‘UF22-127-1’ has been observed to have long-season performance in landscape trials in Gainesville, Florida.

When compared to the female parent ‘UF21-58-2’, ‘UF22-127-1’ has large, highly lobed and ruffled leaves that are slightly longer than they are wide. Additionally, ‘UF22-127-1’ has leaves that are predominantly colored strong brown with purplish red colored veins. In contrast, ‘UF21-58-2’ has smaller leaves that are twice as long as they are wide. Further, ‘UF21-58-2’ has leaves that are colored bright crimson red with chartreuse margins that are more serrated. ‘UF22-127-1’ has a vigorous upright habit with a spreading form that is well-branched, whereas ‘UF21-58-2’ is less vigorous, and more upright in form with less lateral branching and a less spreading form.

DESCRIPTION OF THE FIGURES

This new Coleus cultivar ‘UF22-127-1’ 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 ‘UF22-127-1’ as is shown and described herein;

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 RHS Colour Chart of The Royal Horticultural Society of London (RHS), 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 ‘UF22-127-1’ 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.
