BACKGROUND OF THE INVENTION
The present Invention relates to
a new and distinct cultivar of Hosta plant, botanically known as
and hereinafter referred
to by the cultivar name 'Karin'.
The new Hosta was discovered by
the Inventor in a controlled
environment in Noordwijk, The
Netherlands, as a whole plant
mutation of the 'Fortunei'
not patented, in 1994.
Plants of the new Hosta have a wider
and more white margin than plants of
Asexual reproduction of the new
cultivar by divisions harvested in
Noordwijk, The Netherlands, has
shown that the unique features of
this new Hosta are stable and
reproduced true to type in
BRIEF SUMMARY OF THE INVENTION
Plants of the cultivar Karinhave
not been observed under all possible
environmental and cultural
conditions. The phenotype may vary
somewhat with variations in
environment such as temperature,
light intensity, daylength,
irrigation amount and frequency,
and/or fertilizer rate without,
however, any variance in genotype.
The following traits have been
repeatedly observed and are
determined to be the unique
characteristics of Karin. These
characteristics in combination
distinguish Karin as a new and

flowers that are positioned
above the foliage on strong
and erect scapes.
Plants of the new Hosta can be
compared to plants of the variegated
'Francee', not patented. Compared to
plants of the new Hosta, plants of
the cultivar 'Francee' have a narrower
leaf margin and thinner leaves.
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
colored reproductions of this type.
Colors in the photographs may differ
slightly from the color values cited
in the DETAILED BOTANICAL DESCRIPTION which more accurately
describe the actual colors of the

a typical flowering plant of Karin
grown in a container.

second sheet is a close-up view of
typical flowers of Karin.
The photograph at the bottom of
the second sheet is a close-up view
