Patent Information for 'Great Escape'

According to the U.S. government, a new Hosta cultivar is an "invention". Therefore, it is eligible to receive a patent, just like Edison's electric light bulb. In the case of hostas and other plants, a patent means that for the next 20 years, nobody may propagate and sell this cultivar without providing compensation to the owner of the patent. This is a different process than registering a Hosta with The American Hosta Society.
The application for a patent must include a tremendous amount of information about the plant. Measurements of every conceivable part of the plant are given in metric terms. The color of all plant tissues are given in terms of representations on the Royal Horticultural Society Colour Chart (RHS).
Shown below is the extensive patent information for this cultivar as it was listed on FreePatentsOnline.com:


BACKGROUND OF THE INVENTION The present invention relates to a new and distinct cultivar of Hosta, botanically known as Hosta tardiana (Note) and hereinafter referred to by the name 'Great Escape'. The new Hosta is a naturally-occurring branch mutation of the Hosta tardiana cultivar 'Halcyon', not patented. The new Hosta was discovered and selected by the Inventor in a controlled environment in Barneveld, The Netherlands in 2002. Asexual reproduction of the new Hosta by tissue culture in a controlled environment in Barneveld, The Netherlands since 2003, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations. BRIEF SUMMARY OF THE INVENTION The cultivar Great Escapehas not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 'Great Escape'. These characteristics in combination distinguish 'Great Escape' as a new and distinct cultivar of Hosta: o 1. Broadly spreading foliage with upright flower scapes. o 2. Green and white variegated foliage. o 3. Violet-colored flowers that are positioned above the foliage on strong scapes. o 4. Good garden performance. Plants of the new Hosta differ from plants of the parent, the cultivar 'Halcyon', primarily in leaf coloration as plants of the cultivar 'Halcyon' have solid green-colored leaves. Plants of the new Hosta can be compared to plants of the cultivar First Frost, not patented. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta and the cultivar First Frostdiffered in the following characteristics: o 1. Young leaves of plants of the new Hosta were green and white in color whereas young leaves of plants of the cultivar First Frost' were green and yellow in color. o 2. The white-colored portion of leaves of plants of the new Hosta was larger in area than the white-colored portion of leaves of plants of the cultivar First Frost. BRIEF DESCRIPTION OF THE PHOTOGRAPHS The accompanying colored photographs illustrate the overall appearance of the new Hosta, 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 Hosta. The photograph on the first sheet comprises a side perspective view of a typical flowering plant of 'Great Escape' grown in an outdoor nursery. The photograph at the top of the second sheet is a close-up view of typical flowers of 'Great Escape'. The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of 'Great Escape'. DETAILED BOTANICAL DESCRIPTION The aforementioned photographs and following observations, measurements and values describe plants grown in containers in Barneveld, The Netherlands, under commercial practice during the late summer in an outdoor nursery with day temperatures ranging from 14° C. to 35° C. and night temperatures ranging from 5° C. to 18° C. Plants had been growing for about one year when the photographs and description were taken.

RHS Colour Chart - The Royal Horticultural Society in the United Kingdom has produced a color tool that resembles a paint chart with over 920 samples. It is used by horticulturists around the world to identify colors of flowers, fruits and plant parts in order to bring a level of consistency. Each color has its own unique name along with a number and letter code.
