Abstract: A new and distinct cultivar of Hosta plant named `Orange Star`, characterized by its outwardly spreading foliage with upright flower scapes; thick dark green and pale yellow to white variegated leaves; light violet to white-colored flowers that are positioned above the foliar plane on strong scapes; and good garden performance.
Claim: It is claimed:

1. A new and distinct Hosta plant named `Orange Star` as illustrated and described.
Description: Botanical designation: Hostahybrid.

Cultivar denomination: `ORANGE STAR`.


The present invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta hybrid and hereinafter referred to by the name `Orange Star`.

The new Hosta plant is a naturally-occurring whole plant mutation of the Hosta hybrid `June Fever`, disclosed in U.S. Plant Pat. No. 15,340. The new Hosta plant was discovered and selected by the Inventor in a controlled outdoor nurseryenvironment in Barneveld, The Netherlands in May, 2006.

Asexual reproduction of the new Hosta plant by divisions in a controlled outdoor nursery environment in Barneveld, The Netherlands since August, 2006, has shown that the unique features of this new Hosta plant are stable and reproduced true totype in successive generations.


Plants of the new Hosta have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 `Orange Star`. These characteristics in combination distinguish `Orange Star` as a new and distinct cultivar of Hosta plant: 1. Outwardlyspreading foliage with upright flower scapes. 2. Thick dark green and pale yellow to white variegated leaves. 3. Light violet to white-colored flowers that are positioned above the foliar plane on strong scapes. 4. Good garden performance.

Plants of the new Hosta differ primarily from plants of the parent, `June Fever`, in the following characteristics: 1. Plants of the new Hosta grow slower than plants of `June Fever`. 2. Leaves of plants of the new Hosta are thicker thanleaves of plants of `June Fever`. 3. Under low light conditions, leaves of plants of the new Hosta maintain their variegation whereas leaves of plants of `June Fever` loose their variegation.

Plants of the new Hosta can be compared to plants of `Sweet Innocence`, not patented. Plants of the new Hosta and `Sweet Innocence` differ primarily in leaf coloration as plants of `Sweet Innocence` have light green and pale yellow variegatedleaves.


The accompanying colored photographs illustrate the overall appearance of the new Hosta plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hosta plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `Orange Star` grown in a container.

The photograph on the second sheet is a close-up view of typical flowers and leaves of `Orange Star`.


The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in two-liter containers in an outdoor nursery in Barneveld, The Netherlands and under commercial practice. Plantswere two years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance areused.
