Hosta plant named `Anne`

Abstract

A distinct cultivar of Hosta plant named `Anne`, characterized by its unique variegation pattern with relatively large light yellow margins; thick, rounded leaves; and numerous purple-striped flowers that are positioned well above the foliage on strong and erect peduncles.

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 nonpatented Hosta fortunei cultivar `Aureo Marginata`, 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 variegatiion 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`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it reasonably possible to obtain in colored reproductions of this type.

The first sheet of photographs comprises a top perspective view of a typical potted plant of `Anne`.

The second sheet of photographs comprises a close-up view of typical leaves of `Anne`.

The third sheet of photographs comprises a close-up view of typical leaves and flowers of `Anne`.

The fourth sheet of photographs comprises a close-up view of typical flowers of `Anne`.

The fifth sheet of photographs comprises a close-up view of a typical flower of `Anne`. Leaf and flower colors in the photographs may appear different from the actual colors due to light reflectance.
