| Abstract: |

| Claim: |
It is claimed:
1. A new and distinct Echinacea plant named `Avalanche` as illustrated and described. |
| Description: |
Botanical designation: Echinaceapurpurea.
Cultivar denomination: `Avalanche`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name `Avalanche`.
The new Echinacea originated from a cross-pollination in Bovenkarspel, The Netherlands in July, 2003 made by the Inventor of a proprietary selection of Echinacea purpurea, identified as code number Ec 202-01, not patented, as the female, or seed,parent with a proprietary selection of Echinacea purpurea identified as code number Ec 203-01, not patented, as the male, or pollen, parent. The new Echinacea was discovered and selected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination grown in a controlled environment in IJsselstein, The Netherlands in July, 2004.
Asexual reproduction of the new Echinacea by micropropagation a controlled environment in The Netherlands since 2004, has shown that the unique features of this new Echinacea are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Avalanche 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 `Avalanche`. These characteristics in combination distinguish `Avalanche` as a new and distinct cultivar of Echinacea: 1. Upright,columnar and compact plant habit. 2. Moderately vigorous growth habit. 3. Freely basal branching habit. 4. Large inflorescences with white-colored ray florets and yellow green-colored disc florets.
Plants of the new Echinacea differ from plants of the female parent selection in the following characteristics: 1. Plants of the new Echinacea are more compact than plants of the female parent selection. 2. Plants of the new Echinacea have notbasal branches than plants of the female parent selection.
Plants of the new Echinacea differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Echinacea are not as compact as plants of the male parent selection. 2. Plants of the new Echinacea have largerinflorescences than plants of the male parent selection.
Plants of the new Echinacea can be compared to plants of the Echinacea cultivar Kim's Mophead, not patented. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Echinacea differed from plants of the cultivarKim's Mophead in the following characteristics: 1. Plants of the new Echinacea were more freely branching than plants of the cultivar Kim's Mophead. 2. Ray florets of plants of the new Echinacea were more horizontal and less drooping than ray floretsof plants of the cultivar Kim's Mophead.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Echinacea. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Echinacea.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `Avalanche` grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of `Avalanche`.
The photograph at the bottom of the second sheet is a close-up view of a typical leaf of `Avalanche`.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describeplants grown in Zuidwolde, The Netherlands during the late summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Echinacea production. During the production of the plants, day temperaturesranged from 12.degree. C. to 30.degree. C. and night temperatures ranged from 4.degree. C. to 15.degree. C. Measurements and numerical values represent averages for typical flowering plants. Plants were about one year old when the photographs anddescription were taken.
