Hosta 'Anne'


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:

Description:

The present invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta fortunei, and hereinafter referred to by the cultivar name 'Anne'.

The new cultivar was discovered by the inventor in Noordwijk, The Netherlands, as a naturally-occurring mutation of the non-patented Hosta fortunei cultivar 'Aureo Marginata' (Note), and was observed as a single plant in a group of plants of the parent cultivar of July., 1988.

Asexual propagation of the new cultivar at Noordwijk, The Netherlands, by division and by tissue culture, has shown that the unique features of this new Hosta plant are stable and reproduced true to type in successive generations of asexual propagation.

The new Hosta 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 'Anne'. These characteristics in combination distinguish 'Anne' as a new and distinct cultivar:

1. Unique variegation pattern with relatively large light yellow margins.

2. Thick, rounded leaves.

3. Numerous purple and light purple-striped flowers that are positioned well above the foliage on strong and erect peduncles.

The new Hosta can be compared to its parent cultivar, the cultivar 'Aureo Marginata'. The variegation pattern is different as plants of the new Hosta have a more uniform and larger light yellow margin. In addition, plants of the new Hosta grow faster and have thicker and more round leaves than plants of the cultivar 'Aureo Marginata'.

DETAILED BOTANICAL DESCRIPTION

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.
