Coleus plant ‘UF10-45-12’ is a recently patented, common coleus cultivar (Plectranthus scutellarioides; syn. Solenostemon scutellarioides) that has large chartreuse leaves and prominent red magenta veins.

On Tuesday, Aug. 30, 2016, the U.S. Patent and Trademark Office granted the patent application filed Friday, June 6, 2014, by Florida Foundation Seed Producers, Inc., of Marianna, Jackson County, northwestern Florida, for Coleus plant ‘UF10-45-12.’ The father and son team of David G. Clark and Grayson M. Clark of Gainesville, Alachua County, north central Florida, is identified as the inventors of coleus plant ‘UF10-45-12.’ June Hwu is the U.S. Patent and Trademark Office’s primary examiner of the application for coleus plant ‘UF10-45-12.’

Coleus plant ‘UF10-45-12’ is a cultivar of the common coleus (Plectranthus scutellarioides; syn. Solenostemon scutellarioides). Common coleus is a flowering plant in the Lamiaceae family, known commonly as mints or deadnettles. The shrubby evergreen is an Old World native that claims homelands in India and in Southeast Asia.

The patent application describes 9-week-old plants that were grown from cuttings in 1-gallon pots in a Gainesville, Florida-based glass greenhouse.

Coleus plant ‘UF10-45-12’ presents compact, upright growth with desirable lateral branching. The late season bloomer is found to tolerate heat and to maintain stable foliage color under a range of sunny to shady conditions.

The Clarks’ cultivar, measured from top to soil to plant top, ranges from 32 to 34 centimeters (12.59 to 13.38 inches). Horizontal plant diameter, known as spread, ranges from 46 to 50 centimeters (18.11 to 19.68 inches).

Highly-branched stems are square-shaped. At the soil line, the stem diameter is 1.5 centimeters (0.59 inches).

Each plant has 6 to 8 main, smooth-textured branches. Branch length measures 26 centimeters. Diameter at the branch base ranges from 0.5 to 0.6 centimeters (0.19 to 0.23 inches).

The Clarks refer to The Royal Horticultural Society of London’s color chart for their color identifications. They assign RHS color 145A, light green, to the branch color.

Leaves form opposite arrangements on branches. Each branch bears 14 to 16 leaves. Leaf shape, which resembles an equal-angled triangle, is described as deltoid.

Leaf length ranges from 11 to 13 centimeters (4.33 to 5.11 inches). Leaf width ranges from 8 to 10 centimeters.

Chartreuse leaves are marked with red magenta veins in a netted pattern. The patent describes the upper surface venation color as dark purple red (RHS 59A). The lower surface venation is described as light green (RHS 145A).

The pedigree for coleus plant ‘UF10-45-12’ traces back to ‘Stained Glassworks™ Copper.’ Successive open pollinations with unknown male coleus plants led to coleus plant ‘UF10-45-12’ as the fifth generation descendant of ‘Stained Glassworks™ Copper.’

The Coleus hybrid is an easy grower that classically decorates borders and containers. ‘Stained Glassworks™ Copper’ has a height range of 12 to 24 inches (30.48 to 60.96 centimeters) and an aesthetically equiproportionate spread range. Chantal Aida Gordon, co-founder and editorial director of online gardening site The Horticult describes the coleus hybrid’s toothed, textured leaves as “tye-dyed, stonewashed hot-pink denim.” ‘Stained Glassworks™ Copper’ puts forth inconspicuous blue flower spikes. 

‘UF08-17-2,’ the female coleus plant parent of ‘UF10-45-12,’ has smaller leaves than the new cultivar. Female coleus plant ‘UF08-17-2’ displays deep maroon foliage with bright yellow edges.

Patent applicant and assignee Florida Foundation Seed Producers, Inc. (FFSP) has granted a license to Ball Horticultural Company of West Chicago, DuPage County, northeastern Illinois, for exclusive propagation of the red magenta veined, chartreuse leafed coleus cultivar. Its commercial name is Coleosaurus™ 'UF10-45-12.'

Easy growth, low maintenance and attractive variability all combine to account for the popular naturalization of common coleus and its cultivars beyond their native homelands. Coleus plant ‘UF10-45-12’ represents the appealing creativity that coleus cultivars continue to contribute as bedding and potted plants in private and public landscapes.
