BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct
cultivar of Hosta plant, botanically known as Hosta hybrid and hereinafter referred to by the name 'Justine'.
The new Hosta plant is a naturally-occurring
whole plant mutation of the Hosta hybrid 'June
Fever’, disclosed in U.S. Plant Pat. No. 15,340. The new
Hosta plant was discovered and selected by the
Inventor in a controlled environment in Barneveld, The
Netherlands in May, 2006.
Asexual reproduction of the new Hosta plant by
divisions in a controlled environment in Barneveld, The
Netherlands since August, 2006, has shown that the
unique features of this new Hosta plant are
stable and reproduced true to type in successive
generations.
BRIEF SUMMARY OF THE INVENTION
Plants of the new Hosta have 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 'Justine'. These characteristics in combination
distinguish 'Justine' as a new and distinct cultivar of
Hosta:
o
1. Outwardly spreading foliage with upright flower
scapes.
o
2. Dark green and light green variegated foliage.
o
3. Light violet-colored flowers that are positioned
above the foliage on strong scapes.
o
4. Good garden performance.
Plants of the new Hosta differ from plants of the
parent, 'June
Fever’, primarily in leaf coloration as
leaves of plants of the new Hosta have a broader
green-colored edge than leaves of plants of 'June
Fever'. In addition, plants of the new Hosta have
thicker leaves than plants of 'June
Fever'.
Plants of the new Hosta can be compared to plants
of 'Sweet Innocence’, not patented. Plants of the new Hosta and 'Sweet Innocence' differ primarily in leaf
coloration as plants of 'Sweet Innocence' have light
green and pale yellow variegated foliage.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the
overall appearance of the new Hosta plant,
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
accurately describe the colors of the new Hosta
plant.
The photograph on the first sheet comprises a side
perspective view of a typical flowering plant of 'Justine' grown in a container.
The photograph on the second sheet is a close-up view of
typical flowers and leaves of 'Justine'.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following
observations, measurements and values describe plants
grown in containers in Barneveld, The Netherlands, under
commercial practice during the late summer in an outdoor
nursery. Plants were two years old when the photographs
and description were taken. In the following
description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except
where general terms of ordinary dictionary significance
are used.
