Abstract: A new cultivar of Hosta plant named `Lady Guineverre` that is characterized in having variegated foliage and a large number of flowers. The leaves of `Lady Guineverre` have wide yellow-green centers with narrow dark green margins. In combination, these traits set `Lady Guineverre` apart from other varieties of Hosta known to the inventor.
Claim: It is claimed:

1. A new and distinct cultivar of Hosta plant named `Lady Guineverre` as herein described and illustrated.
Description: Botanicalclassification: Hosta hybrid.

Variety denomination: `Lady Guineverre`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of plaintain lily that is grown for its thick, furrowed, variegated leaves. The new cultivar is known botanically as Hosta and will be referred to hereinafter by the cultivar name`Lady Guineverre`.

`Lady Guineverre` was discovered by the inventor in a cultivated area of Noordwijk, Netherlands in 1996 as a naturally occurring branch sport of the parent plant Hosta `Elizabeth` (not patented). `Lady Guineverre` was selected, by the inventor,for its unique variegated leaves with dark green margins and yellow-green centers.

The plant most similar to `Lady Guineverre` is the parent plant Hosta `Elizabeth`. `Lady Guineverre` differs from `Elizabeth` in its variegated foliage and number of flowers. The leaves of `Lady Guineverre` have wide yellow-green centers withnarrow dark green margins. The leaves of `Elizabeth` are all green. `Lady Guineverre` also flowers more prolifically than the parent plant `Elizabeth`.

Asexual reproduction of the new cultivar was first accomplished in a cultivated area of Roelofarendsueen, Netherlands in 1997 using tissue culture. The characteristics of the new cultivar have been determined stable and are reproduced true totype in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of `Lady Guineverre`. These traits in combination distinguish the new cultivar from other varieties known to the inventor. `Lady Guineverre` has not beentested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions. 1. Hosta `Lady Guineverre` exhibits large, furrowed leaves. 2. Hosta `Lady Guineverre` has a largerquantity of flowers than the parent plant. 3. Hosta `Lady Guineverre` exhibits leaves with narrow dark green margins and wide yellow-green centers. 4. Hosta `Lady Guineverre` exhibits purple flowers.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the distinguishing traits of `Lady Guineverre`.

The photograph on Sheet 1 shows a side view of the entire plant.

The photograph on top of Sheet 2 shows a close up of the flowers.

The photograph on bottom of Sheet 2 illustrates the yellow-green center and dark green margins on a leaf.

All photographs were taken in Noordwijk, Netherlands of field grown plants.

All photographs have been made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THEPLANT
