BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct
cultivar of Hosta plant, botanically known as Hosta fluctuans, and hereinafter referred to by the
cultivar name 'Magic Fire'.
The new Hosta was discovered by the Inventor in a
controlled environment in Barneveld, The Netherlands, as
a whole plant mutation of the Hosta fluctuans
cultivar 'Sagae ', not patented, in June, 1998.
Asexual reproduction of the new cultivar by divisions
and by tissue-cultured microplants in a controlled
environment in Barneveld, The Netherlands since January,
2004, 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 Magic Fire 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 'Magic Fire'. These characteristics in combination
distinguish 'Magic Fire' as a new and distinct Hosta
cultivar:
o
1. Relatively compact plant habit.
o
2. Green and pale yellow variegated leaf color.
o
3. Light lavender-colored flowers that are positioned
above the foliage on strong scapes.
Plants of the new Hosta can be compared to plants
of the parent, the cultivar Sagae . In side-by-side
comparisons conducted in Barneveld, The Netherlands,
plants of the new Hosta differed from plants of
the cultivar Sagae in the following characteristics:
o
1. Leaves of plants of the new Hosta were more
cordate than leaves of plants of the cultivar Sagae .
o
2. Leaves of plants of the new Hosta had broad
pale yellow-colored margins whereas leaves of plants of
the cultivar Sagae had very narrow pale yellow-colored
margins.
o
3. Leaves of plants of the new Hosta had eight
vein pairs whereas leaves of plants of the cultivar
Sagae had seven vein pairs.
Plants of the new Hosta can also be compared to
plants of the cultivar Liberty, disclosed in U.S. Plant
Pat. No. 12,531. In side-by-side comparisons conducted
in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar Liberty in the following characteristics:
o
1. Leaves of plants of the new Hosta were much
smaller than leaves of plants of the cultivar Liberty .
o
2. Leaves of plants of the new Hosta had eight
vein pairs whereas leaves of plants of the cultivar
Liberty had twelve vein pairs.
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
accurately describe the actual colors of the new
Hosta.
The photograph at the top of the sheet comprises a side
perspective view of a typical flowering plant of 'Magic
Fire' grown in a container.
The photograph at the bottom of the sheet is a close-up
view of typical flowers and a typical leaf of 'Magic
Fire'.
DETAILED BOTANICAL DESCRIPTION
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. Plants used for the
aforementioned photographs and the following description
were about two years old and grown in 17-cm containers
in a glass-covered greenhouse and under conditions which
closely approximate commercial production conditions
during the spring in Barneveld, The Netherlands. During
the production of the plants, day temperatures were
about 20° C. and night temperatures were about 16° C.
