Abstract: A distinct cultivar of Hosta plant named `Orange Marmalade`, characterized by its medium sized, puckered broadly ovate variegated leaves of moderate substance, said leaves emerging yellow centered with an irregular blue-green margin and having additional streaks of yellow or greenish yellow between the margin and leaf center with the center of leaves becoming light yellow or near white; and light lavender flowers positioned on straight scapes in midsummer.
Claim: I claim:

1. A new and distinct cultivar of Hosta plant named, `Orange Marmalade`, as illustrated and described.
Description: Latin name: Hostahybrida.

Varietal denomination: `Orange Marmalade`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta hybrida cultivar name, `Orange Marmalade`.

The new cultivar was discovered by the inventor as a naturally occurring whole plant mutation of the non-patented Hosta cultivar, `Paul's Glory`, in April 2000, in a nursery in Chapel Hill, N.C., United States of America.

Asexual reproduction of the new cultivar by tissue culture in 2001 at Rochelle, Ill., United States of America has shown that the unique features of this new Hosta plant are stable and reproduced true to type in successive generations of asexualreproduction.

BRIEF SUMMARY OF THE INVENTION

Plants of the cultivar `Orange Marmalade` have not been observed under all possible environmental and cultural conditions. The phenotype may vary with changes in environmental conditions such as temperature, light intensity, day length, amountand frequency of irrigation and/or fertilizer rate, without any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of `Orange Marmalade`. These characteristics in combination distinguish the hosta as a new and unique cultivar. 1. Medium sized, puckeredbroadly ovate variegated leaves of moderate substance comprising a compact medium sized clump. Substance is equated to the new overall appearance of the thickness of the leaf. It is frequently measured by rubbing the leaf between the fingers and thumb. "Moderate substance" means that the leaf is not thin but feels substantial. However, it is not thick to be leathery. 2. Leaves emerge yellow centered with an irregular blue green margin, leaves having additional streaks of yellow or greenish yellowbetween the margin and leaf center, center of leaves becoming light yellow or near white, depending on the amount of direct sunlight, later in the season. 3. Light lavender flowers are positioned on straight scapes in midsummer.

The new hosta can be compared to its parent cultivar, `Paul's Glory`, not patented. Plants of the new hosta emerge brightly variegated compared to plants of the parent that emerge almost a solid blue color. The color of the center of the leafof the new plant is lighter in color throughout the growing season and is more varied with streaks of yellow (9C to 9B) and green (144A) than are found in the leaf center of the parent plant (154D). The new hosta also makes a smaller, more compact clumpwith shorter flower scapes when compared to `Paul's Glory`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 color reproductions of this type. Colors in the photographs may differ slightly fromthe color value cited in the detailed botanical description, which accurately describe the actual colors in the new Hosta.

FIG. 1 shows the plant at mid-season with brightly variegated color.

FIG. 2 shows a comparison of an early color leaf on the bottom and a mid-season color of the leaf on the top.

FIG. 3 shows a close-up photograph of the late season color of the leaf.

FIG. 4 shows the late season flowering plant.

FIG. 5 shows a late season flowering Hosta plant (Paul's Glory) taken at the same time and location as the novel cultivar show in FIG. 4.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe four-year oldplants, as depicted in the accompanying color photographs, which were grown outdoors in plastic containers in Boonton, N.J., United States of America. Botanical classification: Hosta hybrida `Orange Marmalade`. Parentage: Naturally occurring wholeplant mutation of Hosta cultivar `Paul's Glory`. Propagation: Method.--By division and tissue culture. Plant description: Plant shape.--Compact, open mound, dome-shaped. Growth habit.--Initially upright when young, leaves becoming outwardly arching. Culture.--Light to medium shade in moist soil. Plant type.--Herbaceous perennial. Plant height.--About 17 inches from the soil level to the top of the leaf plane. Plant diameter.--About 32 inches. Vigor and growth rate.--Moderate.
