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 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:
o
1. Plant of small size with upright to gradually arching
foliage;
o
2. Cordate leaves with deep-green margins and
yellow-green centers, shiny surface above and matte
surface below;
o
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.

disease resistance is typical of that of other
hostas. |
