Abstract: A new cultivar of hybrid Hosta, `Grand Marquee`, characterized by its unique variegated foliage with wide blue-green margins and creamy white centers, its upright, mounding and relatively compact plant habit, and pale lavender flowers positioned above the foliage on strong and erect flower scapes.
Claim: It is claimed:

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

Cultivar designation: `Grand Marquee`.

BACKGROUND OF THE INVENTION

The present invention, Hosta `Grand Marquee`, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta hybrid, hereinafter referred to as `Grand Marquee`.

The inventor discovered the new cultivar, `Grand Marquee`, in a block of Hosta `Carder Blue` (unpatented) at his nursery in Kensington, Conn. in the summer of 1997. `Grand Marquee` is a naturally occuring whole plant mutation of `Carder Blue`. `Grand Marquee` was selected as unique for its variegated leaf pattern of wide blue-green margins surrounding white centers and its smaller overall plant size in comparison to `Carder Blue`. `Carder Blue` has foliage that is blue-green in color andnon-variegated.

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in Kensington, Conn. in the spring of 2001. Asexual reproduction of the new cultivar by division and tissue culture has shown that the unique features of`Grand Marquee` are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish `Grand Marquee` as a new and unique cultivar of Hosta. 1. `Grand Marquee` has variegatedfoliage with wide medium blue-green margins and centers that emerge bright green, change to a creamy yellow, and finally change to a creamy white as the leaves mature. An intermediate area, bright green in color exists between the center and margins. The parental plant, `Carder Blue`, is non-variegated. 2. The foliage of `Grand Marquee` exhibits a heavy substance but lacks the heavily rugose and cupped nature of the leaves of `Carder Blue`. 3. `Grand Marquee` reaches a height of about 30 cm (12in) and a spread of about 64 cm (25 inches) at maturity. `Carder Blue` reaches a height of about 96 cm (38 in) and a spread of about 45 cm (18 in). 4. `Grand Marquee` blooms for about 3 to 4 weeks in late summer with pale lavender flowers on scapesabout 38 to 43 cm (15 to 17 in) in height.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken of mature plants of `Grand Marquee` as grown outdoors in Kensington, Conn.

Figure One was taken in June and provides an overall view of new cultivar.

The photograph in Figure Two is of a close-up view of the flowers of `Grand Marquee` and was taken in August.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Hosta.

DETAILEDBOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 4 year-old plants of the new cultivar as grown outdoors in Kensington, Conn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has notbeen tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionarysignificance are used. Botanical classification: `Grand Marquee` is a cultivar of Hosta of hybrid origin. Parentage: Naturally occurring whole plant mutation of Hosta `Carder Blue` (not-patented). General description: Blooming period.--About 3 to 4weeks in late summer. Plant habit.--Herbaceous perennial. Clump-forming, upright vase-shaped, mounded foliage of medium size. Height and spread.--Reaches about 30 cm in height (about 38 to 43 cm in bloom) and about 64 cm in width. Hardiness.--Zone3-8. Culture.--Light shade to medium shade, Moist soils of moderate fertility. Diseases and pests.--No susceptibility or resistance to diseases or pests has been observed for `Grand Marquee`. Thick substance of leaves may confer slug resistance. Rootdescription.--Freely branched, fleshy. Propagation.--In vitro propagation is the preferred method utilizing typical methods for Hosta, division are also possible.
