Abstract

A new and distinct cultivar of Cotinus plant named ‘Kolcot’, characterized by its upright and outwardly spreading plant habit; freely branching growth habit; dark green-colored leaves; early and freely flowering habit; and large showy and feathery inflorescences.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Continus coggygria cultivar Kolcot.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Cotinus plant, botanically known as Cotinus coggygria, and hereinafter referred to by the name ‘Kolcot’.
The new Cotinus was discovered as a cross-pollination of two unidentified selections of Cotinus coggygria, not patented. The new Cotinus was discovered and selected by the Inventor in 1998 as a single flowering plant in a controlled environment in Boskoop, The Netherlands, within a population of the progeny resulting from the cross-pollination.
Asexual reproduction of the new Cotinus by cuttings was first conducted in Boskoop, The Netherlands in 1998. Since then, asexual reproduction by cuttings has shown that the unique features of this new Cotinus are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Kolcot 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kolcot’. These characteristics in combination distinguish ‘Kolcot’ as a new and distinct Cotinus:
1. Upright and outwardly spreading plant habit.
2. Freely branching growth habit.
3. Dark green-colored leaves.
4. Early and freely flowering habit.
5. Large showy and feathery inflorescences.
Plants of the new Cotinus differ primarily from plants of the parent selections primarily in growth habit and foliage coloration.
Plants of the new Cotinus can be compared to plants of the Cotinus cultivar Royal Purple, not patented. In side-by-side comparisons conducted in Boskoop, The Netherlands, plants of the new Cotinus differed from plants of the cultivar Royal Purple in the following characteristics:
1. Plants of the new Cotinus were more freely branching than plants of the cultivar Royal Purple.
2. Plants of the new Cotinus had green-colored leaves whereas plants of the cultivar Royal Purple had red-colored leaves.
3. Plants of the new Cotinus flowered during the first growing season whereas plants of the cultivar Royal Purple did not flower until after the first growing season.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Cotinus showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Cotinus. The photograph comprises a side perspective view of a typical two-year flowering plant of ‘Kolcot’ grown in an outdoor nursery in Boskoop, The Netherlands.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Boskoop, The Netherlands, in an outdoor nursery under full sun conditions. The photographs and the observations and measurements were taken in June, 2001; plants used for the observations and measurements were about 16 months old. During June, day temperatures averaged 17° C. and night temperatures averaged 10° C. Color references are made to The Royal Horticultural Society Colour Chart, 2001 edition, except where general terms of ordinary dictionary significance are used.
