Abstract

A new and distinct cultivar of Eupatorium plant named ‘Snowball’, characterized by its upright and relatively compact plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; creamy white-colored inflorescences; strong peduncles; and good garden performance.

Description

Botanical designation: Eupatorium maculatum.
Cultivar denomination: ‘SNOWBALL’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Eupatorium plant, botanically known as Eupatorium maculatum, and hereinafter referred to by the name ‘Snowball’.
The new Eupatorium plant originated during the summer of 2005 from an open-pollination of Eupatorium maculatum ‘Atropurpureum’, not patented, as the female, or seed, parent with an unknown selection of Eupatorium maculatum, as the male, or pollen, parent. The new Eupatorium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Hummelo, The Netherlands during the summer of 2006.
Asexual reproduction of the new Eupatorium plant by cuttings in a controlled greenhouse environment in Rijpwetering, The Netherlands since the summer of 2006, has shown that the unique features of this new Eupatorium plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Eupatorium have not been observed under all possible environmental conditions and cultural practices. 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 ‘Snowball’. These characteristics in combination distinguish ‘Snowball’ as a new and distinct Eupatorium plant:
    • 1. Upright and relatively compact plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely basal branching habit.
    • 4. Freely flowering habit.
    • 5. Creamy white-colored inflorescences.
    • 6. Strong peduncles.
    • 7. Good garden performance.
Plants of the new Eupatorium differ primarily from plants of the female parent, ‘Atropurpureum’, in leaf and flower color as plants of ‘Atropurpureum’ have very dark green-colored leaves and lilac purple-colored flowers.
Plants of the new Eupatorium can be compared to plants of Eupatorium rugosum ‘Chocolate’, not patented. In side-by-side comparisons plants of the new Eupatorium differ primarily from plants of ‘Chocolate’ in the following characteristics:
    • 1. Plants of the new Eupatorium are more compact than plants of ‘Chocolate’.
    • 2. Plants of the new Eupatorium have larger inflorescences than plants of ‘Chocolate’.
    • 3. Leaves of plants of the new Eupatorium are lighter in color than leaves of plants of ‘Chocolate’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Eupatorium 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 Eupatorium plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Snowball’ grown in an outdoor nursery.
The photograph at the top of the second sheet is a close-up view of typical inflorescences of ‘Snowball’.
The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Snowball’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in an outdoor nursery during the autumn in Lisserbroek, The Netherlands and under conditions and practices which approximate those generally used in commercial Eupatorium plant production. During the production of the plants, day temperatures ranged from 12° C. to 26° C. and night temperatures ranged from 4° C. to 16° C. Plants were three years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
