plant named ‘SMNCCPP3’

Abstract

A new and distinct cultivar of Cotinus plant named ‘SMNCCPP3’, characterized by its upright and outwardly spreading plant habit; freely branching habit; dense and bushy appearance; leaves that are initially greyed purple in color becoming dark green with development; freely flowering habit; inflorescences with numerous light greyed purple-colored pedicel hairs; and good garden performance.

Description

Botanical designation: Cotinus coggygria.

Cultivar denomination: ‘SMNCCPP3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Cotinus plant, botanically known as Cotinus coggygria and hereinafter referred to by the name ‘SMNCCPP3’.

The new Cotinus plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to create new Cotinus plants with strong branches and attractive plant form and flower coloration.

The new Cotinus plant originated from an open-pollination during the summer of 2011 in Grand Haven, Mich. of Cotinus coggygria ‘Little Ruby’, not patented, as the female, or seed, parent with an unknown selection of Cotinus coggygria as the male, or pollen, parent. The new Cotinus plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich. during the spring of 2013.

Asexual reproduction of the new Cotinus plant by softwood stem cuttings in a controlled environment in Grand Haven, Mich. since the spring of 2013 has shown that the unique features of this new Cotinus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cotinus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘SMNCCPP3’. These characteristics in combination distinguish ‘SMNCCPP3’ as a new and distinct Cotinus plant:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Leaves that are initially greyed purple in color becoming dark green with development.
  • 4. Freely flowering habit.
  • 5. Inflorescences with numerous light greyed purple-colored pedicel hairs.
  • 6. Good garden performance.

Plants of the new Cotinus differ primarily from plants of the female parent, ‘Little Ruby’, in plant size as plants of the Cotinus are larger than plants of ‘Little Ruby’. In addition, plants of ‘Little Ruby’ have more reddish-colored developing leaves than plants of the new Cotinus.

Plants of the new Cotinus can be compared to plants of Cotinus coggygria ‘Royal Purple’, not patented. In side-by-side comparisons, plants of the new Cotinus differ primarily from plants of ‘Royal Purple’ in plant form as plants of the new Cotinus are more shrub-like whereas plants of ‘Royal Purple’ are more tree-like. In addition, plants of ‘Royal Purple’ have more maroon-colored developing leaves than plants of the new Cotinus.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Cotinus plant 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 Cotinus plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘SMNCCPP3’ grown in an outdoor nursery.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of typical leaves and inflorescences of a plant of ‘SMNCCPP3’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in three-gallon containers in polyethylene-covered greenhouses in Grand Haven, Mich. and under cultural practices typical of commercial Cotinus production. Plants were five years old when the photographs were taken and two years old when the description was taken. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
