Abstract: A new and distinct cultivar of Hosta plant named `June Fever`, characterized by its relatively compact plant habit; green and light green variegated leaf color; shiny leaves; and lavender-colored flowers that are positioned above the foliage on strong and erect scapes.
Claim: It is claimed:

1. A new and distinct cultivar of Hosta plant named `June Fever`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Hosta tardiana cultivar June Fever.


The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta tardiana, and hereinafter referred to by the cultivar name June Fever.

The new Hosta was discovered by the Inventor in a controlled environment in Barneveld, The Netherlands, as a whole plant mutation of the Hosta tardiana cultivar June, not patented, in May, 1998.

Asexual reproduction of the new cultivar by divisions and by tissue-cultured microplants in a controlled environment in Barneveld, The Netherlands since May, 2000, has shown that the unique features of this new Hosta are stable and reproducedtrue to type in successive generations.


Plants of the cultivar June Fever have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `June Fever`. These characteristics in combination distinguish `June Fever` as a new and distinct Hosta cultivar: 1. Relatively compactplant habit. 2. Green and light green variegated leaf color; leaves shiny. 3. Lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

Plants of the new Hosta are most similar to plants of the parent, the cultivar June. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar June in the followingcharacteristics: 1. Plants of the new Hosta had green and light green variegated leaves whereas plants of the cultivar June had bluish gray-colored leaves. 2. Plants of the new Hosta had shinier leaves than plants of the cultivar June.


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 fromthe color values cited in the detailed botanical description which more accurately describe the actual colors of the new Hosta.

The photograph at the top of the sheet comprises a top perspective view of a typical flowering plant of `June Fever` grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers of `June Fever`.


In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs andthe following description were about two years old and grown in 25-cm containers in a glass-covered greenhouse and under conditions which closely approximate commercial production conditions during the spring and summer in Barneveld, The Netherlands. During the production of the plants, day temperatures were about C. and night temperatures were about C. Botanical classification: Hosta tardiana cultivar June Fever.
