BACKGROUND OF THE INVENTION
The present invention relates to a
new and distinct cultivar of Hosta plant, botanically known as Hosta, hereinafter referred to by the
cultivar name 'Stitch in Time'.
The new plant was discovered by the
Inventor during the summer of 2003
as a non-induced, naturally
occurring whole plant mutation of Hosta 'Summer Breeze' (not patented)
at his nursery in Olathe, Kansas,
USA. Asexual propagation of the new
cultivar by division in 2004 in
Olathe, Kansas and by tissue culture
in 2005 in Waseca, Minnesota., has shown
the unique and distinct
characteristics of this new plant
are stable and reproduce true to
type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The following traits have been
repeatedly observed and are
determined to be the unique
characteristics of 'Stitch in Time'.
These characteristics in combination
distinguish the new Hosta as a new
and unique cultivar:
1. Medium sized clump;
2. Dark green
narrow-centered leaves with a very
wide yellow margin which comprises
approximately 80% of the leaf area;
3. A unique gathering or
stitching effect where the green and
yellow leaf tissues meet; and
4. Pale lavender flowers.
The new Hosta can be compared to its
parent cultivar, 'Summer Breeze'. In
the new Hosta, the margin width is
substantially wider than in the Hosta 'Summer Breeze'. The green
center of the new Hosta is reduced
proportionately to the increased
margin. In addition the parent plant
does not show the unique gathering
or stitching effect where the green
and yellow leaf tissue meets.
The new Hosta cultivar has not been
observed under all possible
environmental conditions. The
phenotype may vary to some extent
with variations in environmental
conditions such as temperature,
fertility and light intensity, but
without any variance in the
genotype.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs
illustrate the overall appearance of
the new cultivar including its
unique traits as a three year old
plant growing in a one gallon
container. The colors are as true as
is reasonably possible with
conventional photography.
FIG. 1 was taken in July and
comprises a top perspective of a
typical plant of the new Hosta.
FIG. 2 was taken in October and
shows the front side of an
individual leaf with the unique
stitching effect between the center
and margin tissue.
FIG. 3 was taken in October and
shows the back side of an individual
leaf.

In the following description, color
references are made to The Royal
Horticultural Society's Colour Chart

terms of ordinary dictionary
significance are used. The following
observations and measurements
describe a three-year old plant
growing in a one gallon container,
as depicted in the accompanying
photographs, which was grown
outdoors in Olathe, Kansas, USA.
