BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct
cultivar of Hosta, botanically known as Hosta tardiana
(Note) and hereinafter referred to by the name 'Great
The new Hosta is a naturally-occurring branch
mutation of the Hosta tardiana cultivar 'Halcyon',
not patented. The new Hosta was discovered and
selected by the Inventor in a controlled environment in
Barneveld, The Netherlands in 2002.
Asexual reproduction of the new Hosta by tissue
culture in a controlled environment in Barneveld, The
Netherlands since 2003, has shown that the unique
features of this new Hosta are stable and
reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The cultivar Great
Escapehas not been observed under
all possible environmental conditions. The phenotype may
vary somewhat with variations in environment and
cultural practices such as temperature and light
intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and
are determined to be the unique characteristics of 'Great
Escape'. These characteristics in combination
Escape' as a new and distinct
cultivar of Hosta:
1. Broadly spreading foliage with upright flower scapes.
2. Green and white variegated foliage.
3. Violet-colored flowers that are positioned above the
foliage on strong scapes.
4. Good garden performance.
Plants of the new Hosta differ from plants of the
parent, the cultivar 'Halcyon', primarily in leaf
coloration as plants of the cultivar 'Halcyon' have solid
Plants of the new Hosta can be compared to plants
of the cultivar First
Frost, not patented. In
side-by-side comparisons conducted in Barneveld, The
Netherlands, plants of the new Hosta and the
Frostdiffered in the following
1. Young leaves of plants of the new Hosta were
green and white in color whereas young leaves of plants
of the cultivar First
Frost' were green and yellow in
2. The white-colored portion of leaves of plants of the
new Hosta was larger in area than the
white-colored portion of leaves of plants of the

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

(Note from Mr PGC:
There is no such plant as Hosta tardiana. The "Tardiana"
is a combination name given to plants that resulted from
an unusual cross of H.
'Sieboldiana'. Those hostas are now known as the
