BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct
cultivar of Hosta, botanically known as Hosta
hybrid and hereinafter referred to by the name 'Fragrant Queen'.
The new Hosta is a naturally-occurring whole
plant mutation of the Hosta hybrid cultivar
'Fragrant King', not patented. The new Hosta was
discovered and selected by the Inventor in a controlled
greenhouse environment in Barneveld, The Netherlands in
August, 2005.
Asexual reproduction of the new Hosta by
divisions in a controlled environment in Barneveld, The
Netherlands since the spring of 2006, 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 Fragrant Queen has 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 'Fragrant Queen'. These characteristics in combination
distinguish 'Fragrant Queen' as a new and distinct
cultivar of Hosta:
o
1. Broadly spreading foliage with upright flower scapes.
o
2. Green and pale yellow variegated foliage.
o
3. Fragrant pale violet to white-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, the cultivar Fragrant King, primarily in leaf
coloration as leaves of plants of the new Hosta
have a broader pale yellow-colored edge than leaves of
plants of the cultivar Fragrant King. In addition,
leaves of plants of the new Hosta are thicker
than leaves of plants of the cultivar Fragrant King.
Plants of the new Hosta can be compared to plants
of the cultivar Sweet Innocence, not patented. In
side-by-side comparisons conducted in Barneveld, The
Netherlands, plants of the new Hosta and the
cultivar Sweet Innocence differed primarily in leaf
coloration as plants of the cultivar Sweet Innocence had
light green and pale yellow variegated foliage.
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 colors of the new Hosta.
The photograph on the first sheet comprises a side
perspective view of a typical flowering plant of 'Fragrant Queen' grown in a container.
The photograph at the top of the second sheet is a
close-up view of the upper surfaces of typical
developing (left) and fully expanded (right) leaves of 'Fragrant Queen'.
The photograph at the bottom of the second sheet is a
close-up view of the lower surfaces of typical
developing (left) and fully expanded (right) leaves of 'Fragrant Queen'.
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 with day temperatures ranging from 14° C. to 35°
C. and night temperatures ranging from 5° C. to 18° C.
Plants had been growing for about 14 months 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.
