BACKGROUND OF THE INVENTION
·
The present Invention relates to a new and distinct
cultivar of Hosta plant, botanically known as
Hosta tardiana
(Note), and hereinafter referred to by the
cultivar name 'June Fever '.
· The new Hosta was discovered by the Inventor in a
controlled environment in Barneveld, The Netherlands, as
a whole plant mutation of the
Hosta tardiana cultivar 'June', not patented, in May, 1998.
· Asexual reproduction of the new cultivar by divisions
and by tissue-cultured microplants in a controlled
environment in Barneveld, The Netherlands since May,
2000, 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
·
Plants of the cultivar June Fever have not been observed
under all possible environmental and cultural
conditions. The phenotype may vary somewhat with
variations in environment 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 'June Fever '. These characteristics in combination distinguish 'June Fever ' as a new and distinct Hosta
cultivar:
·
1. Relatively compact plant habit.
·
2. Green and light green variegated leaf color; leaves
shiny.
·
3. Lavender-colored flowers that are positioned above
the foliage on strong and erect scapes.
·
Plants of the new Hosta are most similar to
plants of the parent, the cultivar June. In side-by-side
comparisons conducted in Barneveld, The Netherlands,
plants of the new Hosta differed from plants of
the cultivar June in the following characteristics:
·
1. Plants of the new Hosta had green and light
green variegated leaves whereas plants of the cultivar
June had bluish gray-colored leaves.
·
2. Plants of the new Hosta had shinier leaves
than plants of the cultivar June.
·
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 new
Hosta.
·
The photograph at the top of the sheet comprises a top
perspective view of a typical flowering plant of 'June Fever ' grown in a container.
·
The photograph at the bottom of the sheet is a close-up
view of typical flowers of 'June Fever '.
·
DETAILED BOTANICAL DESCRIPTION
·
In the following description, color references are made
to The Royal Horticultural Society Colour Chart, 1995
Edition, except where general terms of ordinary
dictionary significance are used. Plants used for the
aforementioned photographs and the following description
were about two years old and grown in 25-cm containers
in a glass-covered greenhouse and under conditions which
closely approximate commercial production conditions
during the spring and summer in Barneveld, The
Netherlands. During the production of the plants, day
temperatures were about 20° C. and night temperatures
were about 16° C.

(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.
'Tardiflora'
and H.
'Sieboldiana'. Those hostas are now known as the
Tardiana Group. |
