Hosta plant named ‘June Spirit’

Abstract

Hosta plant named ‘June Spirit’ with cordate, heavy-substanced, shiny leaves having medium-wide deep-green margins and yellow-green centers. Flowers are medium lavender held attractively above the foliage on small-sized plant.

Description

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘June Spirit’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct hosta plant, Hosta ‘June Spirit’ discovered by Susan Lichacz at a nursery in Zeeland, Mich., USA on Jun. 18, 2008 as an uninduced whole plant mutation in a tissue cultured crop of Hosta ‘June Fever’ U.S. Plant Pat. No. 15,340. 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 ‘June Spirit’ differs from its mutation source parent, ‘June Fever’, as well as all other hostas known to the applicant. Hosta ‘June Fever’ is a mutation from Hosta ‘Halcyon’. ‘Halcyon’ has produced multiple mutations and sports with green to blue-green margins and yellowish to cream centers including these similar but unique from ‘June Spirit’ include: ‘Catherine’ (not patented) and ‘Katherine Lewis’ (not patented), ‘Ripple Effect’ (not patented), ‘Touch of Class’ U.S. Plant Pat. No. 13,080, ‘June’ (not patented), ‘Orange Star’ U.S. Plant Pat. No. 22,384 and ‘Remember Me’ (not patented). Hosta ‘June Spirit’ is most similar to ‘June Fever’, ‘Justine’ U.S. Plant Pat. No. 21,624 and ‘Orange Star’ with all four having the shiny vernicose upper leaf surface, but the new plant has a much wider leaf margin and stiffer, more upright foliage than ‘June Fever’ and is faster growing than ‘Justine’ and ‘Orange Star’. The leaf center of ‘Orange Star’ tends to be a lighter yellow than ‘Justine’ and ‘June Spirit’ under the same light intensity. All of the above have similar flower color.

‘Catherine’ and ‘Touch of Class’ appear to be indistinguishable from each other with a wide blue-green leaf margin, flat glaucous leaf and yellowish leaf center. ‘Remember Me’ has a bright creamy leaf center and blue-green margin with glaucous surface.

There are over 4,900 cultivars registered with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta with another similar number of unregistered cultivars. Hosta ‘June Spirit’ differs from all these registered and unregistered cultivars known to the inventor in the following combined traits:

• • 1. Plant of small size with upright to gradually arching foliage;
  • 2. Cordate leaves with deep-green margins and yellow-green centers, shiny surface above and matte surface below;
  • 3. Numerous flowers of medium lavender held attractively above foliage in mid-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 a leaf close-up of a one-year old plant in the early part of the growing 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 ‘June Spirit’, 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 two-year old plant in a trial garden in Zeeland, Mich. with 50% artificial shade, supplemental water and light fertilizer.
