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 cultivar name 'Foxfire Night Skye'.
The new cultivar was discovered in Marshfield, Wis. by
the inventor as a naturally occurring leaf mutation of a
plant of the non-patented Hosta Hybrid cultivar 'Edge of Night' in 2004. The parent cultivar is characterized by
a medium to large foliage mound 48 inches wide by 24
inches tall. The leaves are broadly ovate and arching, 8
inches wide and 9 inches long. They are dark green in
color. Petioles are green in color and flowers are
described as lavender and tubular. This parent cultivar
was produced by a cross between two breeding cultivars
by
Robert Savory designated as
H. 'Green Gold' ×
H. 'Halcyon' and registered in 1988. (not patented)
The foliage mound of the new Hosta, 'Foxfire Night Skye’, is similar to its parent in size (48 inches (122 cm (8.7 in.) ) wide by 24 inches (62 cm (24 in.) ) high). The leaves are
large (8 inches (20 cm (7.9 in.) ) wide by 9 inches (23 cm (9 in.) ) long)
and dark green in color. The new plant is distinguished
from its parent by a wide cream margin that encircles
the leaf ranging in size from one-half inch (13 mm) in
thickness to one and one half inch (39 mm). Lighter
shades of green and yellow flare from the outer edge of
the dark green center into the adjoining edge of the
white margin. Subsequent asexual propagation by division
at Foxfire Botanical Gardens in 2007 as well as tissue
culture in 2008 at Conyers, Ga. has shown the unique and
distinct characteristics of this new plant are stable
and reproduce true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and
are determined to be the unique characteristics of 'Foxfire Night Skye' as a new and distinct cultivar.
1. Medium to large sized clump.
2. Dark green rounded leaves with wide, creamy, somewhat
irregular margins approximately one-half to one and
one-half inches in width characterized further by
irregular light green and yellow streaking from the dark
green center into the cream margin.
3. Striking contrast between the very dark green center
and bright margin
4. Vigorous growth
The new Hosta can be compared to its all green parent
cultivar, H. 'Edge of Night'. Plants of the new
Hosta have a distinct irregular cream margin enhanced with
light green and yellow streaking between the green
center and white border.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying color photograph (FIG. 1.) illustrates
the overall appearance of the new cultivar, showing the
colors as true as it is reasonably possible to obtain in
colored reproductions of this type. The photograph
comprises a top perspective view of a plant “Foxfire Night Skye” in a cultivated area of the garden. There
may be slight differences in the leaf colors of the
photograph from the actual colors due to light
reflectance.
