Patent Information for 'Journey's End'

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, Hosta ‘Journey's End’, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta sp., hereinafter referred to as 'Journey's End'. The inventor discovered the new cultivar, 'Journey's End’, in summer of 1999 in a tissue culture lab in Waseca, Minnesota. 'Journey's End' originated as a naturally-occurring chimeral mutation of Hosta 'Choo Choo Train' (unpatented). The parent plant, Hosta ‘Choo Choo Train’, is non-variegated with yellow-green foliage. 'Journey's End' is unique in having foliage with green margins surrounding yellow-green centers. The closest comparison plant is 'American Icon' (patent pending), a sibling of 'Journey's End’, which differs in having leaves with the reverse variegation pattern to 'Journey's End’, yellow-green margins and green centers. 'Journey's End' can also be compared to 'Summer Serenade' (not patented), a plant of similar plant stature and leaf variegation pattern. 'Summer Serenade' is a chimeral mutation of golden foliaged 'Piedmont Gold' (not patented). 'Summer Serenade' differs form 'Journey's End' in having less ruffled leaf margins and by emerging earlier in the spring resulting in susceptibility to frost damage, particularly in the Southern portions of the U.S. Asexual reproduction of the new cultivar was first accomplished by the inventor utilizing in vitro propagation in Waseca, Minnesota. in fall of 2002. Asexual reproduction of the new cultivar by division and tissue culture has shown that the unique features of 'Journey's End' are stable and reproduced true to type in successive generations. BRIEF SUMMARY OF THE INVENTION The following traits have been repeatedly observed in trials in Iowa and Minnesota for a period of six years and represent the characteristics of the new cultivar. These attributes in combination distinguish 'Journey's End' as a new and unique cultivar of Hosta. o 1. The foliage of 'Journey's End' is variegated with green margins and yellow-green centers, with margin width ranging from 3 to 9 cm (3.5 in.) comprising about one third to one half of the leaf area. The foliage of the parent plant, 'Choo Choo Train’, is non-variegated with yellow-green foliage. o 2. 'Journey's End' has large broad leaves with a mounded plant habit. o 3. 'Journey's End' reaches a height of about 61 cm (24 in.), exclusive of flower scapes, and a spread of about 132 cm (12.5 in.) in six years. o 4. 'Journey's End' has large leaves with undulating margins when mature. o 5. 'Journey's End' blooms in early to mid summer with pale lavender flowers that arise above the foliage. BRIEF DESCRIPTION OF THE DRAWING The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken in June of mature plants of 'Journey's End' and 'Choo Choo Train' as grown outdoors in Waseca, Minnesota. under the same conditions for six years. FIG. 1 provides an overall view of the foliage and plant habit of the new cultivar, 'Journey's End'. The photograph in FIG. 2 provides a comparison between a leaf of 'Journey's End' (shown on left) and 'Choo Choo Train' (shown on right) as grown in medium shade. The colors in the photographs are as close as possible with the photographic and printing technology utilized and combined with the color values cited in the DETAILED BOTANICAL DESCRIPTION accurately describe the colors of the new Hosta. DETAILED BOTANICAL DESCRIPTION OF THE PLANT The following is a detailed description of six year-old plants of the new cultivar as grown outdoors in Waseca, Minnesota. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 The Royal Horticultural Society Colour Chart, London, England, except where general color terms of ordinary dictionary significance are used. + Botanical Classification: 'Journey's End' is a cultivar of Hosta of hybrid origin. + Parentage: Naturally occurring chimeral mutation of Hosta ‘Choo Choo Train' (not patented). + General description: § Blooming period.

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.
