Abstract

A new and distinct cultivar of Cephalanthus plant named ‘SMCOSS’, characterized by its compact, upright and mounded plant habit; vigorous growth habit; freely branching habit; dense and bushy habit; glossy green-colored leaves that develop anthocyanin in the spring and autumn; spherical head-type inflorescences with numerous white-colored flowers; red-colored fruits; and good garden performance.

Description

Botanical designation: Cephalanthus occidentalis.
Cultivar denomination: ‘SMCOSS’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Cephalanthus plant, botanically known as Cephalanthus occidentalis and hereinafter referred to by the name ‘SMCOSS’.
The new Cephalanthus plant is a product of a controlled breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to create new compact and freely branching Cephalanthus plants with improved flowers and cold hardiness.
The new Cephalanthus plant originated from an open-pollination in 2005 in Grand Haven, Mich. of Cephalanthus occidentalis ‘Britton Lake’, not patented, as the female, or seed, parent with an unknown selection of Cephalanthus occidentalis as the male, or pollen, parent. The new Cephalanthus plant was discovered and selected by the Inventor in 2009 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Cephalanthus plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2009 has shown that the unique features of this new Cephalanthus plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Cephalanthus have not been observed under all possible 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 ‘SMCOSS’. These characteristics in combination distinguish ‘SMCOSS’ as a new and distinct Cephalanthus plant:
    • 1. Compact, upright and mounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit; dense and bushy habit.
    • 4. Glossy green-colored leaves that develop anthocyanin in the spring and autumn.
    • 5. Spherical head-type inflorescences with numerous white-colored flowers.
    • 6. Red-colored fruits.
    • 7. Good garden performance.
Plants of the new Cephalanthus can be compared to plants of the female parent, ‘Britton Lake’. Plants of the new Cephalanthus differ from plants of ‘Britton Lake’ in the following characteristics:
    • 1. Plants of the new Cephalanthus are more compact than plants of ‘Britton Lake’.
    • 2. Leaves of plants of the new Cephalanthus are glossy and develop anthocyanin in the spring and autumn whereas leaves of plants of ‘Britton Lake’ are not glossy and do not develop anthocyanin.
    • 3. Plants of the new Cephalanthus and ‘Britton Lake’ differ in fruit color as plants of ‘Britton Lake’ have green-colored fruits.
Plants of the new Cephalanthus can be compared to plants of the Cephalanthus occidentalis ‘Sputnik’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Cephalanthus differed from plants of ‘Sputnik’ in the following characteristics:
    • 1. Plants of the new Cephalanthus were much more compact than plants of ‘Sputnik’.
    • 2. Leaves of plants of the new Cephalanthus were glossy and developed anthocyanin in the spring and autumn whereas leaves of plants of ‘Sputnik’ were not glossy and did not develop anthocyanin.
    • 3. Plants of the new Cephalanthus and ‘Sputnik’ differed in fruit color as plants of ‘Sputnik’ had green-colored fruits.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Cephalanthus 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 Cephalanthus plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘SMCOSS’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘SMCOSS’.
The photograph on the third sheet is a close-up view of typical fruits of ‘SMCOSS’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer and autumn in ground beds in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial production. Plants were 3.5 years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
