USPP23081P2 - Hosta plant named ‘Goodness Gracious’ - Google Patents

Abstract

Hosta plant named ‘Goodness Gracious’ is a new cultivar with ovate leaves with wide yellow margins and dark green centers, light lavender flowers suitable as a potted plant, for the garden, and for cut flower or leaf arrangements.

Description

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Goodness Gracious’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct Hosta plant, Hosta ‘Goodness Gracious’ discovered by Susan Lichacz at a nursery in Zeeland, Mich., USA as an uninduced whole plant mutation in a tissue cultured crop of Hosta ‘Satisfaction’ (not patented). The new plant has been successfully asexually propagated both by division and by tissue culture at a nursery in Zeeland, Mich. and in both asexual propagation systems found to be stable and produce identical plants that maintain the unique characteristics of the original plant.

BRIEF SUMMARY OF THE INVENTION

Hosta ‘Goodness Gracious’ differs from its parent, ‘Satisfaction’, as well as all other Hostas known to the applicant. The most similar known Hosta cultivars are: ‘Evening Magic’ (not patented), ‘Everglades’ (not patented), ‘Lakeside Symphony’ (not patented), ‘Moonshine’ (not patented), ‘Piedmont Special’ (not patented), ‘Satisfaction’ (not patented), ‘Sentimental Journey’ (not patented), ‘Summer Serenade’ (not patented), and ‘Tylers' Treasure’ (not patented). All of the above are sports (mutations) of ‘Piedmont Gold’ (not patented). Hosta ‘Evening Magic’ has leaves with a yellow center and thin white margin. Hosta ‘Moonshine’ has solid chartreuse foliage. Hosta ‘Lakeside Symphony’ has a muted chartreuse leaf margin with a yellow center. Hosta ‘Sentimental Journey’ has leaves with a light green center and yellow margin. Hosta ‘Summer Serenade’ has foliage with a yellow center and dark green margin, the reverse pattern of ‘Goodness Gracious’. Hosta ‘Goodness Gracious’ has color pattern similar to ‘Everglades’, ‘Piedmont Special’, ‘Satisfaction’ and ‘Tyler's Treasure’ but with a much wider variegation of the leaf margins.

There are over 4,500 cultivars registered with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. Hosta ‘Goodness Gracious’ differs from these and all unregistered cultivars known to the inventor in the following combined traits:

• • 1. Plant size of medium-large with arching foliage.
  • 2. Foliage with coarse marginal undulation or pie-crusting to leaf blade.
  • 3. Leaf blades with narrow dark green centers and very wide lutescent margins.
  • 4. Numerous flowers of light lavender to near white on upright scapes attractively above foliage in early summer.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the three-year old plant demonstrate the overall appearance of the near-mature plant, including the unique traits, grown in a partially shaded garden in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source, direction and temperature may cause the appearance of minor variation in color.

FIG. 1 shows the new plant in a landscape setting early in the growing season.

FIG. 2 shows a close-up of the foliage later in the season.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta ‘Goodness Gracious’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and specimen maturity, but without any change in the genotype. The following observations and size descriptions are of a three-year old plant in a trial garden in Zeeland, Mich. with 50% artificial shade, supplemental water and light fertilizer.
