Coleus plant named ‘ScolK1’

Abstract

A new and distinct cultivar of Coleus plant named ‘ScolK1’, characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching growth habit; and light green-colored leaves with very dark purple-colored margins, veins and bases and light green-colored midveins and splashes.

Description

Botanical designation: Coleus blumei.

Cultivar denomination: ‘ScolK1’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Coleus plant, botanically known as Coleus blumei, and hereinafter referred to by the cultivar name ScolK1.

The new Coleus is a naturally-occurring whole plant mutation of a selection of the Coleus blumei ‘Saber Mix’, not patented. The new Coleus was discovered and selected by the Inventor as a plant within a population of plants of the parent selection in a controlled environment in Ter Aar, The Netherlands in 2001. The selection of the new Coleus was based on its unique leaf coloration.

Asexual reproduction of the new cultivar by terminal cuttings in Ter Aar, The Netherlands since 2001, has shown that the unique features of this new Coleus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ScolK1 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ScolK1’. These characteristics in combination distinguish ‘ScolK1’ as a new and distinct cultivar:

• • 1. Compact, upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Light green-colored leaves with very dark purple-colored margins, veins and bases and light green-colored midveins and splashes.

Plants of the new Coleus differ primarily from plants of the parent selection in leaf coloration.

Plants of the new Coleus can be compared to plants of the cultivar Kiwi Fern, not patented. In side-by-side comparisons conducted in Ter Aar, The Netherlands, plants of the new Coleus differed from plants of the cultivar Kiwi Fern in the following characteristics:

• • 1. Plants of the new Coleus and the cultivar Kiwi Fern differed in leaf shape.
  • 2. Plants of the new Coleus and the cultivar Kiwi Fern differed in leaf coloration as plants of the cultivar Kiwi Fern had brown-colored leaves with yellow-colored margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Coleus.

The photograph at the bottom of the sheet comprises a side perspective view of typical plant of ‘ScolK1’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical leaves of ‘ScolK1’.

DETAILED BOTANICAL DESCRIPTION

The cultivar ScolK1 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown during the summer and fall in Encinitas, Calif., in a polyethylene-covered greenhouse and under conditions which approximate commercial production cultural and environmental conditions. Plants were about six weeks from rooted cuttings and were grown in 13-cm containers. Plants were pinched one time. During the production of the plants, day temperatures averaged 27° C., night temperatures averaged 19° C. and light levels averaged about 4,000 footcandles.
